Answer:
Explanation:
Let mass of cart be m₁ and m₂
m₁ + m₂ = 1.5 kg
At the time of release , their momentum will be conserved
m₁ v ₁ = m₂ v₂
m₁ v ₁ = (1.5 - m₁ ) x 2 v₁
m₁ = 3 - 2m₁
3m₁ = 3
m₁ = 1 kg
m₂ = .5 kg
Exothermic is the answer to your question
Answer:
A
Explanation:
a buffer is a chemical substance that maintains a relatively constant pH
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.
