Explanation:
radio waves, which include visible light waves.
Answer:
C. the bottom
Explanation:
The tires of the car is rolling without slipping. In this case, the bottom of the tire that contacts the surface must be at rest in order to prevent slipping. Of course this is instantaneously. The tire has a translational velocity, v, and also at the bottom a rotational velocity, -v, and the sum is zero for the bottom.
Well, st first we should find <span>initial momentum for the first person represented in the task which definitely must be :
</span>

And then we find the final one :

Then equate them together :
So we can get the velocity, which is

In that way, according to the main rules of <span>conservation of momentum you can easily find the solution for the second person.

200 miles from a nation's coast
Answer:
The head on Collison because you have both cars going (for the sake of it 30mph) and they both collide the energy from that is 60mph because the speed is combined with the two cars.
