Answer:
wave A
Explanation:
shortest wavelength carry the most energy
more energy in a wave, the higher its frequency. The lower the frequency is, the less energy in the wave.
The least potential energy would go at the very bottom of the track. the greatest kinetic energy would be on the upper half of the track and the least kinetic energy would be on the lower half of the track. please review this on google if you are not sure.
Answers:
1) flow of traffic = 
2) average speed = 
3)density of traffic = 
Explanation:
1) to find flow of traffic
we use the relation

where q is the traffic flow and h is average time headway.

insert the value

2) to find average traffic speed
use the relation

where u is average speed S is average spacing and h average time

so inserting the values

3) density of traffic

where K is density of traffic q is flow of traffic and u is average speed
inserting values from above solved parts
