I think is a high-pressure system because it is only in one particular area.
Answer:
The particle speed is constant.
Explanation:
Particles in gases travel quickly in all directions, frequently clashing with each other and the container's edge. The particles gather kinetic energy and travel faster as the temperature rises. The true average speed of the particles is determined by their mass and temperature; larger particles travel more slower around the same temperature than lighter particles.
Thus, the false statement about a wave moving through a constant speed is that:
The particle speed is constant.
Answer:

Explanation:
Let's use the conservation of momentum to solve it.
(1)
- The total initial momentum will be:

- The total final momentum will be:
, but as they stick together after the collision, v1f = v2f = vf.
So we can rewrite (1), using the above information:




Finally, the magnitude of the velocity of the wreckage of the two cars immediately after the collision is:

I hope it helps you!
At the tip of either of the magnets poles
Using the formula,

Here, d is distance, v is the velocity and t is time.
Given,
and
.
Substituting these values in above formula, we get

Thus, the distance traveled by the car is 200 miles
