Freezing (liquid to solid)
Deposition (gas to solid)
Condensation (gas to liquid)
All three of these state changes are a result of a energy loss. When considering energy loss it is best to think of situations where temperature has dropped. Less energy in the system results in less energy the substance is exposed to or has available.
<u>Answer</u>
You should still ensure you are steering straight in the direction of skidding.
Take your foot off the brake unless you are about to hit something. steer in the direction of the skid to straighten your car.
If he moves the piano 4 meters, with 700 newtons of force
in the direction of the motion, then the work done is
Work = (force) x (distance)
= (700 N) x (4 m) = 2,800 joules .
If he does all of that in 2 seconds, then
he did it at the rate of
(work) / (time) = (2,800 J) / (2 sec) = 1,400 watts
(about 1.88 'horsepower' !)
You would add all of them together to make 4. hope this helps((:
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of options. However, <u>Astronauts working in space do not have any external force acting upward or downward on them; meaning there is no contact force pushing or pulling there body and thus experience/feel weightlessness</u>. This causes them to be in a state of constant free fall when they are orbiting the earth. This free fall is similar to what is experienced in elevators and roller coasters in amusement parks.
