The resistance of moving surfaces produces friction.
Friction always results in a loss of energy in the form of heat which enters the atmosphere.
True.
Oil or water clinging to a surface of a jar is an example of...
The last one I believe is either fraction or adhesion.
The maximum velocity of the rock is 64.55 m/s
Answer: Option B
<u>Explanation:</u>
The possessed energy by the objects while motion called kinetic energy. It is directly proportionate to mass and square of velocity. The stored energy in the system called potential energy and expressed as below,


U = spring’s potential energy in certain place
k = the spring constant, in N/m.
x = the spring’s distance is stretched or compressed away from equilibrium
Conservation of energy states energy neither created nor destroyed but change from one form to other. So, using this concept, equating both potential and kinetic energies equation we get,

Given:
m = 12 g = 0.012 kg
k = 200 N/m
x = 0.500 m
Substitute these values we get,


Taking square root, we get,

A book weighing 12 N is balanced on a table. Knowing that the static friction coefficient is 0.5, how much is the friction force worth?
Friction force is
f = u * n
f = 0.5 * 12N
f = 60
