you are using a 1 cir pump which is producing 7.2 gal/min. the pump's shaft is being turned at 1,804 rpm. what is the volumetric efficiency of the pump (as a decimal)?

I can give you some broad recommendations on how to identify generations and people in a pedigree, though.

We commonly use Roman numerals (I, II, III, etc.) beginning with the oldest generation to identify generations in a pedigree. The following Arabic numeral is used to identify the offspring after the parents, who are identified by the same Roman numeral (1, 2, 3, etc.). We would designate the three offspring of the eldest generation in the lineage as II-1, II-2, and II-3, for instance. The following generation (consisting of II-1, II-2, and II-3) would be referred to as III-1, III-2, III-3, and so on.

We use Arabic numbers to identify people within a generation. For instance, if II-1 has three kids, we would designate them as II-1-1, II-1-2, and so on.

I hope this helps! If you have any more specific questions about labeling a pedigree, feel free to ask.

The speed of the snowball before Maya caught it was 104 m/s.

According to the law of conservation of momentum, the sum of the initial momenta will be equal to the sum of the final momenta.

Mass of Max = 15 kg

Mass of Maya = 12 kg

Mass of Snowball = 1.5 kg

Now, using the law of conservation of momentum, we have

The momentum of Max + Momentum of Snowball = Momentum of Maya + Momentum of Snowball

Initial Momentum of Max = 0 (as Max is standing on the shore)

The momentum of Snowball = mv (where m is the mass of the snowball and v is the velocity of the snowball)

The momentum of Maya = mv (where m is the mass of Maya and v is the velocity of Maya with snowball)

Final Momentum of Snowball = (m + m) × v

Now putting these values, Initial momentum = 0 + 1.5 × vi = 1.5vi

Final momentum = 15 × u + 12 (2 u) = 39u (where u is the velocity of Maya with snowball after catching)

Initial Momentum = Final Momentum 1.5vi = 39u

We can write u = 2m/s

Thus putting the value of u, we can calculate the initial velocity of the snowball.

vi = u × (39 / 1.5) = 104 m/s

Thus, the speed of the snowball before Maya caught it was 104 m/s.

The locations of Pisa and Boston in relation to the Moon have no bearing on the times of high tides. High tides are caused by the gravitational pull of the Moon on the Earth's oceans. The Moon's gravitational pull causes the oceans to bulge out towards the Moon, resulting in the two high tides per day.

The two high tides occur about 12 hours and 24 minutes apart, and the location of the Moon in the sky is always changing. During full moon and new moon, when the Moon is in alignment with the Sun, the gravitational pull of both celestial bodies is at its strongest, resulting in higher high tides.

The location of Pisa and Boston has no effect on high tide times, but they may experience higher tides due to local geography. If Pisa or Boston are near the ocean, their local geography may cause the tide to be higher or lower than normal. Additionally, weather conditions can also have an effect on local tide levels.

The electrostatic force between 1nc and 1nc charges at a distance of 1 m from each other is 9.0 × 10^-9 N. The direction of the force is given by Coulomb's law and is along the line joining the two charges. It is either repulsive or attractive based on the type of the charges.

What is Coulomb's law? Coulomb's law is an equation used to calculate the electrostatic force between two charged particles. According to this law, the force between two point charges is proportional to the product of their charges and inversely proportional to the square of the distance between them. The equation for Coulomb's law is given by:

F = k * (q1 * q2) / r^2

Where F is the electrostatic force,k is Coulomb's constant,q1 and q2 are the charges of the particles, and r is the distance between the particles.

Given,

Charge of particle 1, q1 = 1 nc

Charge of particle 2, q2 = 1

distance between particles, r = 1

coulomb's constant, k = 9 × 10^9 N m^2/C^2

Now, we can use Coulomb's law to calculate the electrostatic force between the two charges. Substituting the given values in the equation:

F = k * (q1 * q2) / r^2= 9 × 10^9 N m^2/C^2 * (1 × 10^-9 C) * (1 × 10^-9 C) / (1 m)^2= 9.0 × 10^-9 N

Thus, the electrostatic force between 1nc and 1nc charges at a distance of 1 m from each other is 9.0 × 10^-9 N. The direction of the force is given by Coulomb's law and is along the line joining the two charges. It is either repulsive or attractive based on the type of the charges.

The horizontal component of its velocity after 4.0 s is 129.90 m/s after the projectile is fired from ground level with a speed of 150 m/s at an angle 30° above the horizontal on an airless planet where g = 10.0 m/s2.

What is the horizontal component of its velocity after 4.0 s? To find the horizontal component of its velocity after 4.0 seconds, we have to first find the initial horizontal velocity of the projectile as it was fired at an angle of 30° above the horizontal. We can use trigonometric ratios for that.

Hence, the initial horizontal component of the velocity = Vcosθ=150 cos 30°=150 × √3/2=129.90 m/s.

The vertical component of velocity is given by: Vsinθ=150 sin 30°=75.0 m/s.

Now, we can use the formula for the horizontal displacement of a projectile to find its horizontal velocity after 4 seconds, horizontal displacement of projectile= Vcosθ × t

So, the horizontal displacement of the projectile after 4 seconds= 129.90 × 4= 519.6 m

The can's metal composition measured in volume is -401.94 cm^3

To estimate the amount of material in a cylindrical can, we can use differentials. Let's start by finding the volume of the can. The formula for the volume of a cylinder is:

V = πr^2h

where r is the radius of the cylinder, h is the height, and π is a constant.

The diameter of the can is 15 cm, so the radius is 7.5 cm. The height of the can is 10 cm.

First, we need to find the volume of the metal in the top and bottom of the can. The thickness of the metal is 0.1 cm, so the radius of the top and bottom of the can is reduced by 0.1 cm. Therefore, the volume of the metal in the top and bottom is:

V_top&bottom = π(7.4)^2(0.1) ≈ 16.31 cm³

Next, we need to find the volume of the metal in the sides of the can. The thickness of the metal is 0.05 cm, so the radius of the sides of the can is reduced by 0.1 cm. Therefore, the volume of the metal in the sides of the can is:

V_sides = π(7.4)^2(10) ≈ 2153.78 cm³

The total volume of the can is:

V_total = π(7.5)^2(10) ≈ 1767.15 cm³

To find the volume of the metal that makes up the can, we subtract the volume of the empty space inside the can from the total volume of the can:

V_metal = V_total - V_empty

V_empty = V_top&bottom + V_sides ≈ 2169.09 cm³

Therefore, the volume of the metal that makes up the can is:

V_metal ≈ 1767.15 cm³ - 2169.09 cm³ ≈ -401.94 cm³

Since this result is negative, it does not make sense in the context of the problem. This suggests that there may be an error in our calculations, possibly due to the approximations made when using differentials. Nevertheless, we can use this method to estimate the amount of material in the can, although we may need to use more accurate methods for precise measurements.

The proton accelerates from rest in a uniform electric field of 600 n/c. In order to find the time interval it takes for the proton to reach a speed of 1.50 mm/s.

We need to use the equation v = v₀ + at, where v is the final velocity, v₀ is the initial velocity (which is 0 in this case), a is the acceleration, and t is the time interval. The acceleration of the proton in the electric field is a = E/m, where E is the electric field and m is the mass of the proton. Substituting these values into the equation gives us:

1.50 mm/s = 0 + (600 n/c/1.67 x 10⁻²⁷ kg) x t

The maximum displacement of m  is 199.14, and the time for maximum compression 1.56 seconds.

Given:

Weight, W = 38.6 lb

K(combined stiffness) = 6.4 lb/in

To find:

Maximum displacement of m and the time for maximum compression

Solution: The displacement and velocity of the weight at any time t can be written as below:

x = Acos (ωt + δ)z = Asin(ωt + δ)

Here, A = amplitude

ω = angular frequency = 2π

f = 2π/T

f = frequency = 1/TP = time period

z = vertical displacement of weight from its rest position

x = horizontal displacement of weight from its rest position

For the maximum displacement, the system will be in a state of equilibrium. i.e. ΣF = 0

Let's assume that the weight moves downwards by distance m, the force exerted by each spring will be kx, and the weight exerts a force W = mg on the springs downwards.

Here, m = 38.6 lbs, g = 32.2 ft/s2 and k = K/m = 6.4/38.6 = 0.1657 lb/in

ΣF = -kx - kx - kx - kx - kx - kx + mg = 0-6.4m = -38.6 * 32.2m = 199.14 in (Maximum Displacement of M)The maximum compression will occur when the weight is at the lowest point, i.e. z = -A

Therefore, the time for maximum compression, tmax can be calculated as below.

z = Asin(ωt + δ)At the point of maximum compression, t = tmax

z = -A = -199.14 in (as calculated above)

Therefore,-199.14 = Asin(ωtmax + δ)

Here, A = kx = 6.4×199.14/32.2 = 39.45 inω = 2π/T = 2πf = 2π/4.72 = 1.33 rad/s (where T = time period and f = frequency)

Therefore,-199.14 = 39.45sin(1.33tmax + δ)sin(1.33tmax + δ) = -5.05tmax = 1.56 s

The net force that acts on the stone when it is halfway to the top of the path is zero, this is because of the gravitational acceleration.

When a 1 kg ball is thrown at 10 m/s straight upward, and air resistance is ignored, the net force that acts on the stone when it is halfway to the top of its path is approximately zero.

Since air resistance is ignored, the net force acting on the 1-kg ball is just the force due to gravity. In the absence of air resistance, the acceleration of the ball will remain constant and equal to g, which is -9.81 m/s², because the weight of the ball is mg, where m is the mass of the ball and g is the gravitational acceleration.

So, the net force acting on the ball will be given by:

Net force = m × g = (1 kg) × (-9.81 m/s²) = -9.81 N

W = F × d

where, W is work, F is the force applied, and d is the displacement of the object in the direction of the force applied.

To find the work done, we need to find the force applied on the block. Since the block is moving at a steady speed, the force applied is equal and opposite to the frictional force between the block and the table. The force of friction can be calculated as follows:

Ff = μN

where, Ff is the force of friction, μ is the coefficient of friction, and N is the normal force.

Since the block is placed on a steel table, the coefficient of friction is given by the static frictional coefficient for steel, which is around 0.8. The normal force is equal to the weight of the block.

N = m × g

where, N is the normal force, m is the mass of the block, and g is the acceleration due to gravity.

Substituting the given values:

The battery has to supply more power when two resistors are connected in series than when only one resistor is connected. This is because the power dissipated in a series circuit is equal to the sum of the power dissipated in each resistor.

When two identical resistors are connected in series to a battery, the battery has to supply more power than when only one of the resistors is connected. This is because the resistors offer resistance, which results in the dissipation of energy as heat. The higher the resistance of a resistor, the more power it requires to operate.Resistors consume energy as they offer resistance to the flow of current. The power supplied by the battery is converted to heat energy in the resistor, and the amount of heat energy dissipated is determined by the resistance of the resistor. The greater the resistance of the resistor, the more power it requires to function.

As a result, when two identical resistors are connected in series to a battery, the battery has to supply more power than when only one of the resistors is connected, to produce the same current through the circuit. Therefore, if two resistors of equal value are connected in series, the total power dissipated is twice that of when a single resistor is connected.

the resistance that the circuit should have to have a time constant of 100 microseconds is 5kΩ.

The time constant of an RC circuit is the product of the resistance and capacitance in the circuit, according to the relationship

τ = RC.

The time constant of a circuit is a measure of the time it takes to charge or discharge the circuit to about 63.2% of its final value.

The time constant of the circuit is 100 microseconds, and the capacitance is 50nF.

Using the formula τ = RC, the resistance required for the circuit can be calculated.

To obtain the resistance required for the circuit, rearrange the formula as follows: R = τ/C

where R is the resistance, τ is the time constant, and C is the capacitance.

From the circuit above, if it is charged to 5 Volts, it takes about 2.2 microseconds to discharge to 1 V.

The time it takes for a circuit to discharge from a charged state is given by the formula:

V = V0 e^-t/RC

Where V is the voltage at any point in time,

V0 is the voltage at the start of discharge,

t is the elapsed time,

R is the resistance, and

C is the capacitance.

If the voltage is dropped to 1 V from 5 V, the voltage ratio is 1/5.

The formula for the voltage ratio is V/V0 = e^-t/RC.

Rearrange the formula as follows:-

ln(V/V0) = t/RC

When V = 1 V, V0 = 5 V, R = 5kΩ, and C = 50 nF,

substitute the values into the formula above and

solve for t.

t = -ln(1/5) RC= -ln(0.2) × 5kΩ × 50nF≈ 2.2 microseconds.

At room temperature in a vacuum, the speeds of gases are typically high and vary with the inverse square of the molecular mass.

Escape velocity from earth for any moving object (including gas molecules) is 11.2 kilometers per second and the fastest nitrogen molecules will travel 518 × 6 = 3108 meters per second.

Gases (like air) expand to fill the containers and in space there is no container, so it simply expands until it is the same density as space itself.

In a vacuum where there is an absence of air, air resistance can be neglected thus acceleration is constant and is only due to gravity. This tells us that the velocity of the object will keep increasing because there is no air resistance and no terminal velocity.

The wavelength of a .44 magnum bullet (20.0 grams) travelling at 450.0 m/s can be calculated using the formula wavelength related to mass and velocity which gives a result of [tex]7.36 \times 10^{-29} m[/tex]. Therefore, the correct answer is option(3).
According to de Broglie's wavelength equation,

λ = h/mv = h/p

Where,λ = wavelength, h = Planck's constant, m = mass of the object, v = velocity of the object, p = momentum of the object.

Given that, Mass of the bullet, m = 20.0 g = 0.020 kg

Velocity of the bullet, v = 450.0 m/s

Momentum of the bullet, p = mv = 0.020 kg × 450.0 m/s = 9.00 kg m/s

Now, using the equation for wavelength we can find:

[tex]\lambda = h/p \\= \dfrac{6.626 \times 10^{-34} J s}{ 9.00 kg m/s} \\= 7.362 \times 10^{-35} m[/tex]

Therefore, the wavelength (in meters) of a .44 magnum bullet (20.0 grams) traveling at 450.0 m/s is [tex]7.36 \times 10^{-35} m[/tex]

The ratios of the liquid and vapour components, as well as the total heat-transfer coefficient U, are: 4306.7 kg/h for liquid product flow rate. 133.6 kg/h is the vapour product flow rate. U, the global coefficient of heat transport, is 2.109 kW/m2K.

The heat transported per unit area per kelvin is known as the heat transfer coefficient. Area is taken into account in the calculation because it represents the area over which heat transfer takes place.

Step 1: Calculate the salt in the feed stream's bulk flow rate.

Mass flow rate of the feed = 4535 kg/h

Salt concentration in the feed = 2.0 wt%

Therefore, mass flow rate of the salt in the feed = 4535 kg/h x 0.02 = 90.7 kg/h

Step 2: Calculate the mass flow rate of the water in the feed stream

Mass flow rate of the water in the feed = 4535 kg/h - 90.7 kg/h

= 4444.3 kg/h

Step 3: Calculate the mass flow rate of the vapor and liquid products

The feed is being concentrated from 2.0% to 3.0%. Therefore, the mass fraction of water in the liquid product is 0.97 and in the vapor product is 0.03.

Mass flow rate of the water in the liquid product

= 4444.3 kg/h x 0.97

= 4306.7 kg/h

Mass flow rate of the water in the vapor product

= 4444.3 kg/h x 0.03

= 133.6 kg/h

Step 4: Calculate the overall heat transfer coefficient U

The heat transfer rate can be calculated using the equation:

Q = U x A x ΔT

The steam is supplied at 383.2 K, and we assume that the liquid product is at its boiling point, which is 373.2 K at atmospheric pressure.

ΔT = (383.2 - 373.2) K = 10 K

The heat transfer rate can be calculated using the formula:

[tex]Q = m x Cp x ΔTΔT \\= (311 - 373.2) K \\= -62.2 KQ \\= 4535 kg/h x 4.10 kJ/kg×K x (-62.2 K) \\= -1.469 MW[/tex]

The negative sign indicates that heat is being removed from the feed.

Now we can use these values to calculate the overall heat transfer coefficient U:

[tex]U = Q / (A x ΔT) \\= -1.469 MW / (69.7 m2 x 10 K) \\= 2.109 kW/m2×K.[/tex]
