If the moon was hit by an asteroid there would be a crater mark and possible movement.
if in series one lightbulb burns out the rest are unable to turn on.
In parallel a single light bulb burns out any other light bulbs are able to work.

Answer:
Option C. Light waves can travel through space, sound waves cannot.
Explanation:
Light is an electromagnetic wave which requires no Meduim for propagation. However, sound wave requires a medium for propagation. Since space is empty, sound can not travel through it.
Answer:
Explanation:
Since the universal SI unit for velocity is meters/second, let's convert ft/s to m/s:
We can use the following kinematics equation to solve this question:
What we know:
- The initial velocity,
, is 
- (physics concept) The final velocity must be equal in magnitude but opposite in direction to the initial velocity (
) - Acceleration,
, is acceleration due to gravity at about 
Solving for 
:
