It's equal to the difference in energy between the atom's excited state and its final state.
Answer:
T = 850 N
Explanation:
given,
mass of billboard worker = 800 N
length of scaffold = 4 m
weight of the scaffold = 500 N
worker is standing at 1 m from one end.
Tension in the rope = ?
To calculate the tension in the string we have to balance the clockwise and counterclockwise moment of the system.
Weight of the worker and the weight of the scaffold will be in clockwise direction where as the tension will be in counterclockwise direction
now,
800 x 3 + 500 x 2 = T x 4
4T = 3400
T = 850 N
hence, tension in the rope is equal to 850 N

Kinetic energy is the kind of energy present in a body due to the property of its MOTION.
Potential Energy is the type of energy present in a body due to the property of its STATE.
