Help me pleaseee...A 200kg piano sitting on a platform 2 m high has 3920 J off potential energy. It required 4500 J of work to push the piano up a ramp to the platform. What is the best explanation for the difference between the amount of work required to move the piano and its potential energy?
A) the piano lost mass as it was pushed up the ramp.
B) energy was destroyed moving the piano up the ramp.
C) some of the energy required to push the piano up the ramp was used to overcome friction between the piano and the ramp.
D) the work required to push the piano up a ramp is greater because the force is the same as if it were lifted, but the distance is greater when using a ramp.

Explanation:

The rotation of Earth on its axis causes _______ and _______. The revolution of the Earth around the sun causes the ______.

Answers

Answer:

The revolution of the earth around the sun and the tilt of the earth's axis cause the changing of the seasons.

Explanation:

Final answer:

The Earth's rotation causes day and night, while its revolution causes seasons. This happens due to how the rotation exposes different parts of the Earth to the sun, and how the tilt of the Earth's axis during revolution causes varying sunlight exposure.

Explanation:

The rotation of Earth on its axis causes day and night. This astronomical phenomenon happens because as the Earth rotates, different parts of it are exposed to the Sun's light, creating the cycle of day and night. On the other hand, the revolution of the Earth around the sun causes the seasons. As the Earth orbits the Sun, the tilt of our planet's axis causes different parts of the Earth to receive varying degrees of sunlight throughout the year, which results in the changes in weather conditions we know as seasons.
