A) Transmitted through the medium
The electromagnetic waves with the greatest frequency
on the spectrum are the ones we call "gamma rays".
The electromagnetic waves with the lowest frequency
on the spectrum are the ones we call "radio waves".
Explanation:
Momentum before = momentum after
m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂
(50.0 kg) (0 m/s) + (12.0 kg) (0 m/s) = (50.0 kg) (2.0 m/s) + (12.0 kg) v
v = -8.33 m/s
Answer:
2.45 m
Explanation:
We are given that
Height,h=0.75 m
Initial velocity,
We have to find the height above his own starting point Ed rises.
Initial kinetic energy of Ed=Final potential energy of Ed
According to law of conservation of momentum
Initial kinetic energy of adolf=Final potential energy of adolf
Substitute the values
