A skier going down a mountain has 98,000J of gravitational potential energy, 10,000J of kinetic energy and 2,000J of thermal energy. At the bottom of the mountain, he has 90,000J of kinetic energy. How much thermal energy does he have at the bottom of the mountain? A) 2,000J B) 8,000J C) 20,000J D) 80,000J

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )

it doesn't. it was imagined up in the middle ages.

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
