Explanation:light waves carry energy parallel to the motion Of The wave while sound waves carry energy perpendicular to it
The acceleration is given by:
a = v²/r
a = 10²/5
a = 20 m/s²
This is not a realistic value for a runner because it is very large.
Answer:
Change in momentum of the rider=803.4N
Explanation:
Fnet= mac
N- mg=mrw^2
N = mg + mrw^2
N = mg + mr (2×3.142/T)^2
Where T= period of revolutions
r = radius of ferris wheel
m= mass of rider
N= (52×9.8)+( 52×7)(2×3.142/7)^2
N=803.4N
