Change in molecular composition
irreversible change
Explanation:
chemical change Is an irreversible change so we will only observe permanent change
Answer:
2. The total initial angular momentum is non-zero and total angular momentum is conserved.
Explanation:
Let the mass of the boy be m and v be his velocity . His linear momentum
p = mv , If R be the radius of the circular path of merry go round . When the boy jumps on the merry gold round , he adds an angular momentum to the system .
Angular momentum of the boy with respect to the center of merry go round
L = r x p = r p sin90.
= r p
= m v r
This is the initial angular momentum of the system of boy and merry go round .
Total final angular momentum of the system will also be equal to initial angular momentum , according to law of conservation of angular momentum , since no external torque is acting on the system.
Geothermal power plants use the renewable resource of heat from within the Earth to generate electricity.
Explanation:
The correct statement is that geothermal power plants use the renewable resource of heat from within the Earth to generate electricity.
Geothermal energy is heat energy from within the earth.
- Geothermal energy is not available everywhere on the earth. It is restricted to certain geologic terrains.
- It is a renewable source of energy whose usage cannot be depleted at our current rate of consumption.
- This heat is used to produce electricity in areas where they occur.
