2. 50 mm/s - v=fa
3. B - only process that involves changing waves
Answer:
Explanation:
As we know that the electrostatic force is a based upon inverse square law
so we have
now since it depends inverse on the square of the distance so we can say
now we know that
also we know that
now from above equation we have
Answer:
B.
Explanation:
an individual learns to disassociate himself from a stimulus.
<span>Determined by the distance between objects and the difference in mass between the objects is gravity or gravitational force. Gravity is dependent on those two factors, and is what causes objects on Earth to stay on the ground.
