Technically it’s asking what will happen to the skaters height it will rise to (the skaters highest point) if you change the initial height. Is this what you needed?
Answer:
potential energy = mgh , where m is mass of body , g is acceleration due to gravity and h is given height
since both of the body are at same height above the ground , so the body having greater mass will have more potential energy
that is 20 kg body will have higher P.E

Answer:
Explanation:
Speed of car =22.5miles/hr
U=22.5miles/hour
Applied brake and come to rest
Final velocity, =0
t, =2sec
Given that,
Speed=distance /time
Then,
Distance, =speed, ×time
Converting mile/hour to m/s
Given that
Use: 1 mile= 1600 m, 1 h= 3600s
22.5miles/hour × 1600m/mile × 1hour/3600s
Therefore, 22.5mile/hour=10m/s
Using speed =10m/s
Distance =speed ×time
Distance=10×2
Distance, =20m
The distance travelled before coming to rest is 20m.
Answer:
The correct answer would be answer A
Explanation:
It has to be A because if the seeds are hetrozygous there is a chance that if u make a punnet square that u can get a smooth ressesive seed
