Explanation:
Electrical energy to sound energy
Answer:
Synthesis reaction
Answer:
-5.396Joules
Explanation:
Work is said to be done when a force causes a body to move through a distance and acts in the direction of the force.
Work done = Force × Distance
Given force = mg
Force = 2.20×9.81
Force applied on the string = 21.58N
Distance will be the difference in height = 4.75-5.00
= 0.25m
Negative work done on the pendulum during the first entirely oscillation = 21.58×0.25
= -5.396Joules
