C. reduces the resistance force
The mechanical advantage of a compound machine is related to the mechanical advantage of all the simple machines involved.
True
Explanation:
Mechanical energy (the sum of potential and kinetic energy) is constant:
ME = PE + KE
ME = PE + ½ mv²
PE = ME − ½ mv²
So the slope of the line is -½ of the mass.
The answer
<span>According to Newton’s first law, if no force acts on an object, it will just continue moving in a straight line with a constant speed or at rest
that means that the sum of all acting forces equals 0
</span>so the car must
exert a force between the car and the road to drive at a constant speed on a straight and level road because the both forces must be balances for making it to move <span><span>with a constant speed in a straight line.</span> </span>
