Answer:
1) True, 2) True, 3) False, 4) False, 5) False
Explanation:
1) True. Dissipative energy cannot be recovered, in general it is a form of heat
2) True. The dissipation can be by radiation, heat
3) False. Mechanical energy is divided into K and U but not in equal parts
4) False. When there are dissipative interactions, part of the mechanical energy is set in the form of heat, so its value decreases
5) False. Mechanical energy is the sum of those two energies
Answer:
he performed 100 push-ups, 100 sit-ups, and 100 squats, and ran 10 kilometers each day for over a year.
Explanation:
crazy right
Answer:
\Delta E=1.22\times 10^{-22}J
Explanation:
The energy of electron in any state is given by 
here h is planck's constant n is state of electron L is the infinte potential well m is the mass of electron
We know that 
Potential well dimension = 
Mass of electron 
So energy required to electron to jump from ground state to 3rd state
