Answer:
the answer is b temperature
False
Energy in the form of motion is kinetic energy
Stored energy is called potential energy
The law of conservation of energy implies that energy can neither be created nor destroyed, but can be changed from one form to another.
<h3>
Answer:</h3>
Input work
<h3>
Explanation:</h3>
Concept being tested: Efficiency of machines
Therefore we need to know what is the efficiency of a machine
- Efficiency of a machine is the ratio of work output of machine to the work input expressed as a percentage.
Efficiency = (Work output ÷ Work input) × 100%
- Therefore, if the work input is equal to the work output then the efficiency of the machine will be 100%.
- Most machines are not 100% efficient due to loss of energy in form of heat due to friction of the moving parts of the machine.
Answer:
0.12959085 J
Explanation:
k = Coulomb constant = 
q = Charge = 1.55 μC
d = Distance between charge = 0.5 m
Electric potential energy is given by
In this system with three charges which are equidistant from each other
The potential energy of the system is 0.12959085 J
