Answer:

[tex]a=-3846.46\ m/s^2[/tex]

Explanation:

Given that,

Initial velocity of the ball, u = 22.2 m/s

Final velocity of the ball, v = -14.9184 m/s (minus sign shows opposite direction of motion)

Time for contact, t = 0.00965 s

We need to find the average acceleration of the ball when it is in contact with the ball. The acceleration of an object is equal change in velocity per unit time. So,

[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{-14.9184 -22.2 }{0.00965 }\\\\a=-3846.46\ m/s^2[/tex]

So, the acceleration of the ball is [tex]3846.46\ m/s^2[/tex] towards the opposite direction of motion.

Answer:

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

[tex]\\ \rm\Rrightarrow a=\dfrac{F}{m}[/tex]

[tex]\\ \rm\Rrightarrow a=\dfrac{84}{12}[/tex]

[tex]\\ \rm\Rrightarrow a=7m/s^2[/tex]

[tex] \huge\bf\underline{solution}[/tex]

Mass of given body (m) = 12Kg

Force (F) = 84.0N

We have been asked to find the magnitude of of the acceleration .

[tex] \huge\bf\purple{force = mass \times acceleration}[/tex]

Put all the given value we get

[tex] \sf \dashrightarrow84 = 12 \times acceleration \\ \\ \sf \dashrightarrow \frac{84}{12} = acceleration \\ \\ \sf \dashrightarrow7 {ms}^{ - 2} = acceleration[/tex]

So, the acceleration due to gravity on that planet is 7m/s² .

So Your answer is B) 7.0m/s²

Answer:

5ms^-2

Explanation:

F = 20N, m = 4.0kg, a = ?

Using the formula for Force

F = ma

Then making acceleration the subject of the formula

a = F/m

a = 20N/4.0kg

a = 5ms^-2

Answer:

The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.

With Georgia's motorcycle at  over 4.5 m long and having a mass of 235 kg, Reid’s tangential speed is mathematically given as

vt=12.4m/s

Generally, the equation for the Conservation of momentum  is mathematically given as

mn=m1+m2

Therefore

mn=235+72

mn=307

Therefore

Fc=mn*a

THerefore

[tex]vt=\sqrt{\frac{rFc}{mn}}\\\\vt=\sqrt{\frac{25*1850}{307}}[/tex]

vt=12.4m/s

In conclusion, The tangential  speed is

The photoelectric effect was first proposed by Einstein. He claimed that when a light wave comes in contact with an electron, it has the ability to strip that electron from its atom. It depends on how much energy the light wave is carrying, and what type of atom the light is hitting. We use the photoelectric effect in garage motion sensors.

How much energy does it take to heat 1 kg of water?

The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C. Lead will warm up and cool down fastest because it doesn't take much energy to change its temperature.

The first reason is that in the past humans didn't necessarily see the connections between the oceans and thus labelled them that way separating them into 5 oceans and the names stuck to this day.

Secondly, while all the oceans of the world constitute one large Ocean, people need some way to identify each part of it since it is easier to think when we have different categories instead of one large category.

The rating of the transformers primary and secondary currents will be 360.8A and 180.4A.

From the information given, the rating of the transformer bank is given as 300kVA. The full load primary current will be:

✓3 × V × I = 300 × 10³

✓3 × 480 × I = 300 × 10³

I = 360.8A

Also, the secondary load current will be calculated thus:

Transformation ratio = 240/480 = 0.5

Load current = 360.8 × 0.5

= 180.4 A

In conclusion, primary and secondary currents will be 360.8A and 180.4A.

Answer:

Heat

Explanation:

Heat. The thermal energy that flows from one substance to another when the substances differ in temperature. Thermal equilibrium. The state in which no thermal energy transfer occurs because both substances are at the same temperature. Specific heat.

Heat is the thermal energy that flows from one substance to another when the substances differ in temperature.

Thermal energy is the term used to describe the energy present in a system that is responsible for setting its temperature.

Here,

The average kinetic energy of the particles in a material is measured by its temperature. The overall kinetic energy of the particles in a material is measured by thermal energy.

The temperature and thermal energy of a material increase with the particle velocity.

The amount of thermal energy that is transferred from one media or object to another, or from an energy source to a medium or object, is measured in terms of heat.

Radiation, conduction, and convection are the three mechanisms through which such energy can be transferred.

The heat energy may be transformed into other types of energy, such as mechanical, kinetic energy, etc.

Hence,

Heat is the thermal energy that flows from one substance to another when the substances differ in temperature.

Explanation:

The formula for calculating the magnitude of the resultant vector is expressed as;

[tex]R = \sqrt{(\sum Fx)^2+(\sum Fy)^2}[/tex]

[tex]\sum Fx[/tex] is the sum of distances along the x component

[tex]\sum Fy[/tex]  is the sum of distances along the y component

[tex]\sum Fx = 45 cos 25^0\\\sum Fx = 40.78m\\\\\sum Fy = -45 sin 25^0+30\\\sum Fx = 10.98m\\[/tex]

[tex]R = \sqrt{(40.78)^2+(10.98)^2}\\R = \sqrt{1663.0084+(120.61)}\\R = \sqrt{(1783.6184}\\R = 42.23m[/tex]

Answer:

a) 6m/s, 0m/s, -6m/s

b) 16m, 25m, 16m

Explanation:

For the first part of the problem, use the Kinematic Equation for Final Velocity:

You are looking for the final velocities of the times: 2s, 5s, and 8s (plug those in for t). We also know that the acceleration is going down so it is negative (-2 is plugged in for a). 10 is the initial velocity and it is positive.

For the second part of the problem, use the Kinematic Equation for Displacement:

You are looking for the displacement of the piano at times: 2s, 5s, and 8s (plug in and square at t). Again, the acceleration is negative because it is in the direction of down, so plug -2 in for a. The initial velocity is positive 10. Plugging those numbers in for each variable should get the correct answer.

In a stable ecosystem, the number of predators increases if the number of prey increases.

Predators are the species that are dependent upon prey for their foods. predators actually hunt the prey for their food.

predators are the species that depend upon other living species like deer fish goats etc for example lions depend upon deer, zebras, etc.

while the preys are the species who depend upon the plants for their food so if the number of preys will be higher then the number of the predators will also be higher.
