A brass is 1 m long. If the coefficient of expansion in length of the brass is 0.000019/K and the increase in length of the brass is 5.757 mm. How much temperature change occurred?

Answers

The temperature change that occurred when the 1 m long brass experience an increase in length of 5.757 mm is 303 °C

How do I determine the temperature change?

Coefficient of linear expansion is given by the following formula:

α = ΔL / L₁(ΔT)

Where

α is the coefficient of linear expansionΔL is the change in length L₁ is the original lengthΔT is the temperature change

With the above formula, we can obtain the temperature change as illustrated below:

Answers

The magnitude e of the electric field be if the charge is to hit the target on the screen is E = mv₀²yh/0.5qL².

Charge's speed in the x direction is equal to v₀.

The charge's time to reach the screen at a distance L, t = L/v₀

F = qE = ma, which is the force on the charge

When the two equations are equalized, force ma = qE/m and charge a = qE/m

The charge's initial velocity in the y-direction is o, and the vertical distance it covers is given by the equations

y = 0.5 (qE/m) (L/v₀)

y = 0.5qL²E/mv² and y = 0.5at².

Anna holds a 12 D magnifier directly in front of her eye to get a close look at a 19-mm-diameter penny. What is the closest possible distance that she can hold the coin to have it appear in focus? At this distance, how large does the image of the coin appear on her retina? (Assume a typical 25 cm near point and a distance of 1.7 cm between the lens and the retina.)

Answers

The near point of the eye is the shortest distance Anna can hold the coin and still have it appear in focus.

By near point of the eye, what do you mean?

The closest distance at which an object can be placed in front of the eye and still be in focus is the near point of the eye, also referred to as the closest point of distinct vision. To change the eye's focal length and enable it to focus on objects at different distances, changes are made to the pupil's size and the lens of the eye.

The near point for a typical eye is approximately 25 cm.

Use the lens equation,

1/f = 1/d₀ + 1/di

We know that f = 12 D and di = 1.7 cm

Therefore,

1/f = 1/d₀ + 1/di

1/12D = 1/d₀ + 1/(1.7cm)

d₀ = 1/(1/12D - 1/(1.7cm))

d₀ = -1.98cm

The unit will be in cm.

We refer to an object or substance's volume (or how much space it occupies) in terms of its density (its mass).

(a) The density of fresh water is ρwater = 1000 kg/m³

ΣF = 0

ΣF = - (ρwood)g(Vwood) + (ρwater)g(vwood)

two ice skaters suddenly push off against one another starting from a stationary position. the 55-kg skater acquires a speed of 0.175 m/s relative to the ice. what speed does the 70-kg skater acquire relative to the ice?

Answers

The 70-kg skater acquires a speed of -0.125 m/s relative to the ice, meaning that it moves in the opposite direction of the 55-kg skater.

What is speed?

The distance traveled in a unit of time is called speed. It refers to a thing's rate of movement. The scalar quantity known as speed is the velocity vector's magnitude. It has no clear direction.

In this case, the two skaters and the ice are considered as a closed system since no external force is acting on them. Therefore, the total momentum before and after the skaters push off against one another must be the same.

We can use this principle to find the speed of the 70-kg skater relative to the ice. Let's call the speed of the 55-kg skater v1 and the speed of the 70-kg skater v².

We can use the formula for momentum p = m*v,

where m is the mass and v is the velocity.

The total momentum before the skaters push off is 0 (since they are at rest) and the total momentum after the skaters push off is:

p = (55 kg) * (0.175 m/s) + (70 kg) * v²

Since the total momentum is conserved, we can set the initial momentum to be equal to the final momentum:

0 = (55 kg) * (0.175 m/s) + (70 kg) * v²

Solving for v2, we get:

v2 = -(55 kg * 0.175 m/s) / 70 kg = -0.125 m/s.

Answers

It would take the plane approx. 93 seconds to fly once around circle, traveling at a constant speed of 180 m/s

What is meant by speed ?

Speed is defined as the rate of change of position of object in any direction. Speed is measured as the ratio of distance to the time in which that distance was covered.

The circumference of a circle is 2 * pi * radius, where pi is approximately 3.14. Therefore, circumference of the circle with a radius of 2700 m is:

2 * pi * 2700 m = 16,800 m

Given, constant speed of 180 m/s

As, distance = speed * time

So, time = distance / speed

time = 16,800 m / 180 m/s

Answers

The work done by the gravitational force on rock 1 can be calculated using the work-energy theorem. This theorem states that the net work done on an object is equal to the change in its kinetic energy.

What is gravitational force?

Gravitational force is the attractive force between two objects that is proportional to their masses and inversely proportional to the square of the distance between them. It is the weakest force in nature and is the reason why objects with mass are attracted to each other. This force was first described by Isaac Newton in his law of universal gravitation, which states that the force between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them.

Since the rock is launched from rest at a height of h0 and then returns to the same height, its kinetic energy does not change and therefore the net work done on the rock is zero. This means that the work done by the gravitational force on the rock is also zero, since the only force acting on the rock is the gravitational force.

A large raindrop the type that lands with a definite splat--has a mass of 0.014 g and hits your roof at a speed of 8.1 m/s.a. What is the magnitude of the impulse delivered to your roof? Express your answer with the appropriate units.b. If the raindrop comes to rest in 0.37 ms, what is the magnitude of the force of the impact? Express your answer with the appropriate units.

Answers

The impulse delivered to the roof is  -0.115 Ns and the magnitude of the force of the impact is -31.17 kN.

a. Impulse is defined as the product of the force acting on an object and the time over which the force is applied. In this case, the impulse delivered to the roof is the product of the force acting on the raindrop and the time it takes for the raindrop to come to a stop after hitting the roof. Since we don't know the time of impact, we can use the impulse-momentum theorem which states that the impulse of a force acting on an object is equal to the change in momentum of the object.

The impulse delivered to the roof is given by J = Δp = pf - pi

The initial momentum of the raindrop is given by pi = m * vi = 0.014g * 8.1 m/s = 0.115 Ns

Since the final velocity of the raindrop is zero (it comes to rest), the final momentum is zero. Therefore, the impulse delivered to the roof is J = pf - pi = 0 Ns - 0.115 Ns = -0.115 Ns

b. To find the force of the impact we can use the equation: F = J/t

where F is the force of the impact, J is the impulse delivered to the roof, and t is the time it takes for the raindrop to come to a stop after hitting the roof.

We have that t = 0.37 ms = 0.00037 s

So F = J/t = -0.115 Ns / 0.00037 s = -31167.57 N or -31.17 kN

Here, the negative sign of the force tells us that the force is opposite to the direction of motion, which means that the force is acting to stop the motion of the raindrop.

A light bulb is 60cm from a concave mirror with a focal length of 20cm. Use ray tracing to determine the location of its image. Is the image upright or inverted? Is it real or virtual. Verify your results by doing the calculations.

Answers

As we draw the ray diagram, the image seems to fall between the f and c. It was real, inverted and magnified image.

Here it is given that the focal length is 20 cm.

So the curvature of the mirror will be 2f = 2 ×20 = 40 cm.

The light bulb is 60 cm away from the concave mirror. So the object is beyond C. As per theory, if an object is beyond c, the image will fall between c and f, and it will be a real, diminished and inverted image. The ray diagram we draw also give the same result.

Lets look into calculations.

The distance between object, the image and focal length is related by the equation,

   1/f = 1/v +1/u

     v is the distance of image from mirror

      u is the distance of the object from the mirror.

So , 1/v = 1/f - 1/u

            = 1/20 - 1/60

           = 60-20 / 1200 = 1/30

So v = 30 cm.

This proves the diagram we draw is correct.

So the image will be formed 30 cm away from the mirror and it will be real, inverted, diminished image.
