Answer:
F
Explanation:
A carousel can be made to rotate using different sources of energy. One may decide to use electric energy, manual effort, water energy or heat energy as in a candle carousel.
When the candle is lit, heat energy is supplied and warm air rises heating up the air near the carousel eventually causing it to start rotating.
Hence heat from the candle leads to a current of warm air that rises up, causing the carousel to start rotating.
Answer: -
A solar nebula is a rotating cloud of gas and dust from which the sun and the planets formed.
A planetesimal is a small body from which planet originated in the early stages of development of the solar system.
Kupier belt is region of the solar system that is just beyond the orbit of Neptune and that contains bodies made mostly of ice.
This is the region of the solar system that contains small bodies that are made mostly of ice.
Thus Pluto is formed from the huge disk of ice and debris beyond the outer planets. Comets originating from the Kupier belt are also composed of ice and debris.
Answer:
