Answer:
It has been converted into thermal energy due to friction
Explanation:
According to the law of conservation of energy, energy cannot be created nor destroyed, but only transformed from one form into another.
Applied to this problem, it means that the total initial energy of the spring-toy system must be conserved.
Therefore:
- At the beginning, the total energy stored in the spring is 10 J
- After the toy is released, the total energy must still be 10 J.
In reality, we are told that the kinetic energy of the car is only 8 J. The other 2 J have not been destroyed, but they have been converted into thermal energy, due to the presence of frictional forces that act against the motion of the toy car.
B is the right answer glad I could help !!
Hello there! Yes, this is a TRUE statement.
Conditional means something happens on the condition of something else happening. In this case, the something else happening is if the child "child is well-behaved or meets set expectations", and the thing happening because of this is the caregiver's " love, affection, and acceptance". If the child was not any of the things listed, the caregiver would not be the things listed.
I hope this helps, have a great day! :)
Thermal energy gives the particles of the substance kinetic energy because temperature is an average measure of kinetic enegy of the particle. If we give them thermal energy the particle will move faster, gaining enough energy to escape and become free. For example, from solid to liquid, the particles would espace their fixed position and be free to move as a liquid.
