Answer:
The answer to your question is Power = 24 Watts
Explanation:
Data
time = 3 s
Work = 72 J
Power = ?
Power is defined as the rate at which a work is done.
Formula
Power = Work / time
-Substitution
Power = 72/3
-Simplification
Power = 24 Watts
-Conclusion
The Power exerts by 72 J of work in 3 seconds is 24 watts.
Answer: Elastic energy is the energy store in a.. compacted spring; an extended elastic band; and a drawn bow.
Chemical potential energy is position of electrons in specific substance bonds that can be broken (energizes).
Answer:

Explanation:
= 1
h = Planck's constant = 
The energy is given by

Energy is also given by

The frequency of light emitted would be 
Static electricity is the BUILT UP STORE of electron charges [e-] between a pair of objects, while current electricity is the FLOW of electrons between these objects.
Static electricity is a transfer of charge from one static body to another, resulting in an imbalance in positive and negative charges, while electric current is the flow of electrons, from one static body to another.
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge. Static electricity is named in contrast with current electricity, which flows through wires or other conductors and transmits energy.
