Answer:
Light and sound waves are different in the sense that:
Light can travel without a medium, and is a physical particle
Sound is a vibration in a medium
Light can be altered by a different medium
Same with sound
Explanation:
There's no answer list, but here are some answers.
<span>(Momentum is Zero) 0 = (26.0 kg + 55.0 kg)v + (5.40 kg)(+10.0 m/s)
</span>velocity = -.667 m/s
Answer:
The ball takes 5s to reach the ground
Explanation:
in order to solve this problem we use the kinematics equation with gravity as acceleration:

we replace the values

We solve this quadratic equation:
t=5s
t=-6s (this solution has not physical sense)
