chemical to thermal to electromagnetic
Explanation:
The best statement that shows the energy transformations that took place is from chemical to thermal to electromagnetic energy.
- In all isolated systems, energy is neither created nor destroyed but transformed from one form to another according to the law of conservation of energy.
- The firewood contains a chemical potential energy at rest. This energy is contained in the carbon chains of organic compounds it houses.
- When combustion takes place, kinetic energy in form of thermal energy is liberated. The bulk is in form of heat.
- This energy dissipates in all direction as a form of radiant electromagnetic energy in the infra-red range.

Answer:
The momentum of the bowling ball is 53.4 kg-m/s.
Explanation:
We have,
Mass of a bowling ball is 8.9 kg
Speed of the ball is 6 m/s
It is required to find the momentum of the ball. The momentum of an object is given in terms of its mass and speed as :
p = mv
So, the momentum of the bowling ball is 53.4 kg-m/s.
Answer:
0.1m
Explanation:
k = 64N/m
Ep = 0.32J
x = ?
Ep = 1/2 * kx²
make x the subject of the formula
x² = 2Ep/k
x = √(2Ep/k)
x = √(0.64/64)
x = √0.01
x = 0.1m
