You travel in a circle, whose circumference is 8 kilometers, at an average speed of 8 kilometers/hour. if you stop at the same point you started
from what is your average velocity?
oa o kilometers/hour
ob 2 kilometers/hour
oc 4 kilometers/hour
d. 8 kilometers/hour
oe 16 kilometers/hour

Your average velocity is zero km/h ⇒ answer A

Explanation:

Displacement is the change in position of an object

It is measuring from the starting position to the final position of

the object

If the starting and ending position are the same, then displacement of

the object is zero

Velocity of is displacement divided by time

You travel in a circle, whose circumference is 8 kilometers, at an average

speed of 8 kilometers/hour

That means your speed of traveling is 8 km/h

We need to find your average velocity If you stop at the same point

you started

→ Velocity = displacement ÷ time

You end your trip at the same point you started from

That means your displacement is zero

→ Displacement = 0

→ Velocity = 0 ÷ time

Your average velocity is zero km/h

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
