Answer;
C.It is the minimum amount of material needed to sustain a fission reaction.
Explanation;
-A critical mass is the smallest or the minimum amount of fissile material needed for a sustained nuclear chain reaction. A critical mass must be achieved in order for the chain reaction to continue and release the atomic energy. A critical mass is needed for both a nuclear reactor and an atomic or hydrogen bomb.
-The critical mass of a fissionable material depends upon its nuclear properties (specifically, the nuclear fission cross section), its density, its shape, its enrichment, its purity, its temperature, and its surroundings.
The role of thermal energy is to balance the electrical energy lost from the light bulb.
<h3>
Energy conservation</h3>
The law of energy conservation states that energy can neither be created nor destroyed but can be transformed from one form to another.
<h3>Thermal energy</h3>
This is a form of energy that occurs due to rise in temperature.
The role of thermal energy is to balance the electrical energy lost from the light bulb.

Answer:
Vmax=11.53 m/s
Explanation:
from conservation of energy

Spring potential energy =potential energy due to elevation
0.5*k*x²= mg
=mgh
0.5*k*2.3²= 430*9.81*6
k=9568.92 N/m
For safety reason
k"=1.13 *k= 1.13*9568.92
k"=10812.88 N/m
agsin from conservation of energy

spring potential energy=change in kinetic energy
0.5*k"*x²=0.5*m*
10812.88 *2.3²=430*
=11.53 m/s
Answer:
when there is a change in the direction
Explanation:
The particle will move faster when there is a change in the direction on the movement
