Which segment shows the substance changing from a gas to a liquid

Answer:

Y-X

Explanation:

- For any substance, solid is the state with least temperature (because the particles have less energy: in fact, they are bond together, so they are not free to move), gas is the state with highest temperature (because particles have more energy, since they are totally free to move), while liquid state lies in the middle.

- In the graph, we can therefore associate U with the solid state (least temperature), W with the liquid state, and Y with the gas state (largest temperature).

- The section labelled with V corresponds to the solid-liquid transition, where the temperature remains constant (during phase transitions, temperature does not change). Similarly, the section labelled with X corresponds to the liquid-gas transition.

- The problem is asking us for the segment representing the change from gas to liquid. According to all the things we have written above, we can say that this is represented by the Y-X segments. In fact, in Y the substance is still a gas: by removing heat, the temperature decreases (we are going towards the left in the graph), until we reach segment X, which represents the transition from the gas to liquid state.

A car slid off an icy 10m bridge and landed 12m away from the bridge. How much time was the car in the air? (Hunt: Projectile)
Contact [7]

You will use the height of the bridge from the ground.

Solution:

Formula to be used is y=Viy(t)+g(t^2)/2

Where:

Vi=initial velocity which is 0 m/s

 y=10 m

Gravitational acceleration or g =9.8m/s^2

T= time you need

Substitute all the given to the formula

10m=(0m/s)(t)+(9.8m/s^2)(t^2)/2

10mx2=9.8m/s^2(t^2)

Now isolate the variable you want to find which is T or time

10mx2/9.8m/s^2=t^2

20m/9.8m/s^2=t^2

Square root of 2.04= square root of t^2

T=1.43 secs

The answer is 1.43 seconds

To develop the problem it is necessary to apply the equations related to the moment of inertia.

The given values can be defined as,

M = 1.0 kg

r = 0.5 m

m = 10 g

I = 0.280 kg.m^2

According to the definition of the moment of inertia applied to the exercise we can arrive at the equation that,

I = I_{rim} + n * I_{spoke}

Where n is the number of spokes necessary to construct the wheel.

I_{rim} = M*r^2 = 1.0 * 0.5^2

I_{spoke} = \frac{1}{3} * m * r^2 = \frac{1}{3}* 10 * 10^-3 * 0.5^2

Replacing the values at the general equation we have,

0.280 = 1.0 * 0.5^2 + n * (1/3 * 10 * 10^-3 * 0.5^2 )

Solving for n,

n = 36

Therefore the number of spokes necessary to construct the wheel is 36

PART B) The mass of the wheel is given by the sum of all masses and the total spokes, then

M_w= M + n*m

M_w = 1.0 + 36* 10 * 10^{-3} Kg

M_w = 1.36 Kg

Therefore the mass of the wheel must be of 1.36Kg
