Answer:
12 N
Explanation:
Given,
Mass ( m ) = 3 kg
Acceleration ( a ) = 4 m/s^2
To find : Force ( F ) = ?
Formula : -
F = ma
F
= 3 x 4
= 12 N
Therefore, the force acting on the object is 12 N.
If a person is placed in a large, hollow, metallic sphere that is insulated to the ground and a charge is placed on sphere, the person inside will not be harmed.
Answer:
Potential energy on surface of Mars is 6669000 J
Explanation:
As we know that the weight of the climber on the surface of Earth is given as 675 N
So weight of the climber on the Mars is given as
Now we know that gravitational Potential energy is given as
A- plane mirror because its surface is plane
