Answers

Answer 1

The energy released during the cooling of 45g of -175 degrees C steam to 90 degrees is 419,481,317,781,101,700,417,600 J

When steam at -175 degrees Celsius is cooled to 90 degrees Celsius, it undergoes a phase change from a gas to a liquid. During this process, energy is released in the form of heat as the molecules of the steam lose kinetic energy and transition to a lower energy state. This energy release is due to the formation of intermolecular forces between the water molecules, which creates a more stable state of matter.

To calculate the amount of energy released, we can use the formula Q = mΔTc, where Q is the energy released, m is the mass of the steam, ΔT is the change in temperature, and c is the specific heat capacity of water. Since the steam undergoes a phase change, we need to also include the energy required for this process, which is known as the latent heat of vaporization.

The energy released during the cooling of 45g of -175 degrees C steam to 90 degrees C can be calculated as follows:

Q = (45g) * (90°C - (-175°C)) * (4.184 J/(g·°C)) + (45g) * (2257 J/g)

= 419,481,317,781,101,700,417,600 J

This calculation shows that an enormous amount of energy is released during the cooling of steam, due to the large latent heat of vaporization of water. This energy can be harnessed and used for various purposes, such as generating electricity in power plants or powering steam engines.

Answers

Centripetal force is the portion of a force exerted on an object in curvilinear motion that is directed at the axis of rotation or the centre of curvature. A fictitious force that moves in a circle and is directed away from the centre is called centrifugal force.

What is meant by Centripetal force?Any force that induces a shift in velocity direction toward the centre of a circular motion is referred to as a centripetal force.Centripetal force is caused by the part of the force that is perpendicular to the velocity. The tension in a tether ball's rope, the gravitational pull of Earth's gravity on the Moon, the friction between roller skates and a rink's floor, the force a car feels on a banked road, and the forces acting on a centrifuge's tube as it spins are just a few examples.Centripetal forces are any net forces that result in a consistent circular motion.

b) The tension in the chain if a child of mass 49.1 kg sits in a seat is calculated to be 650.79 N.

a) By drawing a free body diagram, we represent the two types of forces on the seat. They are represented by the equation, sum of forces in the y direction,

∑F = ma

T cos θ − mg = 0

T = mg / cos θ

Sum of forces in the centripetal direction,

v = √(gr tan θ)

First, let us find the radius of the path,

r = 7.4 / 2 + 1.81 sin 26.6°

What is the power (in Watts) of a bus that uses 35 N of force to move 20 m in 5s?

Answers

Power is the rate at which work is done, and it is measured in watts (W). It can be calculated using the formula:

Power = Work / Time

Work can be calculated using the formula:

Work = Force x Distance x cos(theta)

where Force is measured in Newtons, Distance is measured in meters and theta is the angle between the force and displacement vectors.

As we are not giving any value for the angle between force and displacement vectors, we can assume it's zero degree, so the cos(0)=1

So we can plug in the given values to find the work done:

Work = 35 N x 20 m x 1 = 700 J

Now we can calculate power:

Power = 700 J / 5 s = 140 W

Therefore, the power of the bus is 140 Watts

A wire ring of internal radius 3cm and external radius 3.2 cm is rested on the surface of a liquid and then raised. An extra pulling force equivalent to the weight of 3.03g is required before the film breaks than it is after. Calculate the surface tension of the liquid.

Answers

The surface tension of the liquid is 24.1 g/m.

How can we calculate the value of the surface tension of the liquid?

To calculate the surface tension of the liquid, we can use the formula:

surface tension = (extra force required) / (length of the film)

extra force required = 3.03 g

internal radius = 3 cm = 0.03 m

external radius = 3.2 cm = 0.032 m

The length of the film can be calculated as the circumference of the external ring minus the circumference of the internal ring:

length of the film = (2 * pi * external radius) - (2 * pi * internal radius)

= (2 * pi * 0.032 m) - (2 * pi * 0.03 m)

= 0.1257 m

So, the surface tension can be calculated as:

surface tension = (3.03 g) / (0.1257 m)

= 24.1 g/m

The surface tension of the liquid is 24.1 g/m.

Answers

If the boy swings the toy with a linear velocity of 2m/s, the toy will move in a circle. The force required to maintain the toy's motion IS 750g * m/s^2

The linear velocity of an object moving in a circle is related to its angular velocity (measured in radians per second) and the radius of the circle. The linear velocity is given by the equation: v = r * w, where v is the linear velocity, r is the radius of the circle, and w is the angular velocity.

In this case, the radius of the circle is 0.8m and the linear velocity is 2m/s. Therefore, the angular velocity of the toy can be calculated as: w = v/r = 2m/s / 0.8m = 2.5 rad/s.

The toy has a mass of 150g and it moves in a vertical circle with a radius of 0.8m and a linear velocity of 2m/s, so it will move in a circle. The force required to maintain this motion is the centripetal force, which is given by the equation F = m * a, where F is the force, m is the mass of the toy and a is the centripetal acceleration. The centripetal acceleration is given by the equation a = v^2/r, where v is the linear velocity and r is the radius of the circle.

So, the force required to maintain the toy's motion is F = m * a = 150g * (2m/s)^2 / 0.8m = 750g * m/s^2

5. Find the mass of a book that has a weight of 4.7 newtons.

Answers

The mass of the book is 0.48 g

According to the Newton's second law of motion

Force(F)= Mass(m) × Acceleration(a)

Here, Force (F) = 4.7 Newton (N)

The acceleration due to gravity (g) = 9.8 m/s²

We have to find the mass of the book.

Putting the given values in the equation F=m×a

                                                               4.7 N = m × 9.8 m/s²

if a cars engine is 27.5 effeicient at converting the fuels energt ubti necgabucal eberft if 1L of gasoline has 33.5J of input energy how much useful energy output will 2.50L of fuel provide

Answers

The efficiency of the engine is given 27.5%. The input energy of 2.5 L gasoline is 83.75 J. Then, the energy output will be 23.01 J.

What is engine efficiency ?

The efficiency of an engine is the ratio of its output work done to the energy input. No engine can have 100% efficiency. Hence, some energy is lost in the form of heat.

Given that, the efficiency of the car's engine is 27.5 %. Input energy of 1 L gasoline is 33.5 J. Then, energy input for 2.5 l is:

input energy = 2.5  × 33.5 = 83.75 J.

Engine efficiency = energy output/ input energy × 100

O/ 83.75J × 100 = 27.5 %

O/83.75 = 0.275

then output energy = 83.75 × 0.275 = 23.01 J.

Therefore, the energy output of the fuel is 23.01 J.

Stiner objected and insisted on the competitive allowance for the life of the contract.
