Weight = (mass) x (acceleration of gravity)
We know the mass. All we need now is the acceleration of gravity. All that other stuff about velocity and time is chaff, launched to confuse our radar.
C) decomposition because the molecules are breaking down (decomposing)
Answer:
A faster because teens what to drink it more when. they see there parents do it
<span>A. kinetic energy. </span>
Friction converts kinetic energy into heat, and so it represents a net loss of mechanical energy. When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into heat. As demonstrated by the use of friction created by rubbing pieces of wood together to start a fire, kinetic energy is converted to heat whenever motion with friction occurs. The friction produced by brake pads in a car must generate a quantity of heat equal to the kinetic energy of the car and as a result, the brakes get quite hot.
