Velocity is the speed of an object moving in a definite direction. The velocity of an object can be uniform or variable. When an object moving along a straight line at variable speed, we can Express the magnitude of its rate of motion in terms of average velocity.
Average velocity=Initial velocity+Final velocity/2
The SI unit of velocity is m/s.
Answer:
c.Racquetball
because the lighter the object the more force it needs to go
The force between them if the distance between them is doubled is a. F/4
Explanation:
- To find the answer, we can use Coulomb's law where it is defined as the force between two point charges is directly proportional to the magnitude of the point charges and proportional inversely to the distance between them.
- The equation can be written as, where k is the Coulomb constant, are the point charges, and r is the distance between these two point charges.
- To find the answer to this question, just substitute 2r in the place of r hence, you will get as the new force when the distance is doubled.
