Waves transport

Answer:

d)energy

Explanation:

Waves can transfer energy over distance without moving matter the entire distance. For example, an ocean wave can travel many kilometers without the water itself moving many kilometers. The water moves up and down—a motion known as a disturbance. It is the disturbance that travels in a wave, transferring energy.

What processes will a gas undergo when deposition and condensation occur?
ICE Princess25 [194]
When  condensation happens to a gas element, there will be an instance where it will suddenly turn into a liquid element. On the other hand, deposition is a process where the gas will turn into a solid element once it happens.

Which person would experience the greatest force of impact in a sudden collision? A 200 lb. man traveling 20 mph b 150 lb. woman
Alisiya [41]

Answer:

<em>The 150 lb woman at 30 mph would experience the greatest force of impact in a sudden collision.</em>

Explanation:

<u>Momentum </u>

The force of impact exerted on an moving object that suddenly stops or changes its movement is measures by the physics magnitude called Impulse, which can be computed with the formula

I=F.t

Where F is the force and t is the time that force acts to produce the impact on the object. The impulse is also defined as the change in the momentum of the object:

I=\Delta p=p_2-p_1

Or equivalently

I=m(v_2-v_1)

The question describes four situations where different persons and object suffer impact that make them stop from their moving state. Thus v_2=0 and the impulse is

I=-m.v_1

We are only interested in the relative magnitudes of each case, so we won't consider the sign in the calculations

Case 1: A 200 lb. man traveling 20 mph  

I_1=200(20)=4000\ lb.mph

Case 2: A 150 lb. woman at 30 mph

I_2=150(30)=4500\ lb.mph

Case 3: A 35 lb. infant at 75 mph

I_3=35(75)=2625\ lb.mph

Case 4: A 75 lb. child at 55 mph

I_4=75(55)=4125\ lb.mph

By comparing the results, we can see that the 150 lb woman at 30 mph would experience the greatest force of impact in a sudden collision.
