The correct answer to the question is : D) Be moving at a constant velocity.
EXPLANATION:
As per Newton's first laws of motion, every body continues to be at state of rest or of uniform motion in a straight line unless and until it is compelled by some external unbalanced forces acting on it.
Hence, it is the unbalanced force which changes the state of rest or motion of a body. Balanced force is responsible for keeping the body to be either in static equilibrium or in dynamic equilibrium.
As per the options given in the question, the last one is true for an object under balanced forces.
There is a probability that heat will flow from warmer to cooler substances,
and a probability that heat will flow from cooler to warmer substances.
The probability that heat will flow from a cooler to a warmer substance is
so small that it is ignored. It's accepted as a 'law' of thermodynamics that
heat always flows from higher temperature to lower temperature.
The velocity will remain unchanged (Newton’s 1st Law) unless a force acts on it. If no friction force, then the velocity remains constant.
Explanation:
the average velocity of the car is 15 m/s example I have this on a test
