D) the ability to make things happen
Explanation:
Energy is simply defined as the ability to do work or to make things happen. Energy is important to all aspects of living and non-living things. Based on the law of conservation of energy "energy can neither be created nor destroyed but can be transformed from one form to another".
Different forms of energy exists such as heat, thermal, chemical, mechanical, sound, electrical, e.t.c

Answer:
VR = 0.26 m/s
Explanation:
m = 0.1 kg M = 0.1 kg
v = 0.31 m/s Vi = 0 m/s
the kinetic energy of the system initially is:
Ki = 1/2×m×(v^2) + 1/2×M×(Vi)^2
= 1/2×(0.1)×(0.31)^2
= 4.805×10^-3 J
then, we told that the system after collision only retains a fraction 0.69 of its initial kinetic energy. that is the final kinetic energy of the system is:
Kf = 0.69×4.805×10^-3 J
= 3.31545×10^-3 J
but due equal masses of the bodies, we know that after the collision the only body that would be in motion would be the body that at res and the body that was initially moving will now be at rest.so the kinetic energy is only made by the second body and given by:
Kf = 1/2×M×(VR)^2
3.31545×10^-3 = 1/2×(0.1)×(VR)^2
VR^2 = 0.066309
VR = 0.26 m/s
according to the coservation of linear momentum:
