Static friction is the friction that exists between a stationary object and the surface on which it's resting.
frictional force occurs when you try to push an object alongside a surface.
Answer:
The unit of speed is m/s.
Acceleration due to gravity.
According to the law of conservation of energy,
A. an object loses most of its energy as friction
<u>B. the total amount of energy for a system stays the same</u>
Energy is never lost due to the law of conservation
C. the potential energy of an object is always greater than its kinetic energy
D. the kinetic energy of an object is always greater than its potential energy
Answer:
The electric force between them is 878.9 N
Explanation:
Given:
Identical charge 
C
Separation between two charges 
m
For finding the electrical force,
According to the coulomb's law
Here, force between two balloons are repulsive because both charges are same.
Where 
N
Therefore, the electric force between them is 878.9 N
