To reduce friction between two surfaces, you have to
make the surfaces smoother.
The best way to do that is to introduce a fluid between them,
like grease, oil, or air.
The formula of net Force is:F = mawhere m is the mass of the objecta is the acceleration of the object
thus, if we triple the net force applied to the object:
3F = maa = 3F / m
The acceleration is also tripled since the force is directly proportional to the acceleration.
Answer:
Explanation:
Given
Radius of A is twice of B i.e.
Also Potential of both sphere is same
thus
(b)Ratio of 
Electric Field is given by 
thus 
----1
----2
Divide 2 by 1
Answer:
Kinetic energy
Kinetic energy is the motion of waves, electrons, atoms, molecules, substances, and objects.
The answer is C. Any physical property can be observed without changing the identity of the substance. That’s one of the main things that separates a physical and chemical property.
