Work = force × displacement
532 J = 48 N × d
d ≈ 11 m
Answer:
True.
Explanation:
If the sum of the external forces on an object is zero, then the sum of the external torques on it must also be zero.
The net external force and the net external torque acting on the object have to be zero for an object to be in mechanical equilibrium.
Hence, the given statement is true.
A. THE ENERGY THAT IS RELEASED IN A NUCLEAR REACTION.
M =MASS
C^2= SPEED OF LIGHT SQUARED
Answer : A. It decreases and then increases.
Explanation : Troposphere is the lowermost layer of atmosphere.

So, option (A) is correct.
