Answer:
Explanation:
1. The net force acting on an object is the combination of all of the individual forces acting on it.
2. If two forces act on an object in opposite directions, the net force is the difference between the two forces.
3. If two forces act on an object in the same direction, the net force is the sum of the two forces.
Answer:
Explanation:Newton.s law of cooling states that the rate of cooling of an object is proportional to the difference between its own temperatures and temperature of its surroundings. Mathematically,
where is the heat transfer
is heat transfer coefficient
is the heat transfer surface area
is the temperature of the object's surface
is the temperature of the surroundings
