Answer: Their final relative velocity is -0.412 m/s.
Explanation:
According to the law of conservation,

Putting the given values into the above formula as follows.



v = 
= -0.412 m/s
Thus, we can conclude that their final relative velocity is -0.412 m/s.
Answer:
it is easier in zig zag because youll fell less tired and feel more energetic and it will will feel as if it were shorter to go zig zag
I believe that the answer is <span>C. The atmosphere scatters blue light more than yellow light.</span>
Note: I'm not sure what do you mean by "weight 0.05 kg/L". I assume it means the mass per unit of length, so it should be "0.05 kg/m".
Solution:
The fundamental frequency in a standing wave is given by

where L is the length of the string, T the tension and m its mass. If we plug the data of the problem into the equation, we find

The wavelength of the standing wave is instead twice the length of the string:

So the speed of the wave is

And the time the pulse takes to reach the shop is the distance covered divided by the speed:
The total mechanical energy of the ball is the sum of its potential energy U and its kinetic energy K, therefore:

so, the total mechanical energy of the basketball is 118 J.
