If a disk rolls smoothly across a floor, the velocity is zero of the point that is in contact with the floor.
<h3>What is Velocity?</h3>
Observed from a specific point of view and measured according to a specific unit of time, velocity is the direction at which an object is moving and serves as a measure of how quickly its position is changing.
<h3>What is known as velocity?</h3>
A particle or object moves with respect to time when moving at a certain speed, which is expressed vectorially as velocity. Meters per second (m/s) is the commonly used unit for measuring velocity magnitude, also known as speed. A different way to indicate velocity magnitude is with the centimeter per second (cm/s) unit.

Answer:
Explanation:
speed of alien spaceship = .1 c
We shall apply formula of relativistic mechanics to solve the problem
relative velocity =
Here v = v₁ = .1 c
relative velocity = .1c + .1 c / 1 - .1²
= .2 c / .99
= .202 c
The earth would receive the signal at the speed of .202 c .
Answer:
<h2>C. maintenance </h2>
