Answer:
1:4
Explanation:
We have, two identical objects A and B fall from rest from different heights to the ground.
Object B takes twice as long as object A to reach the ground. It is required to find the ratio of the heights from which A and B fell. Let are the height for A and B respectively. So,
We have,
So,
So, the ratio of the heights from which A and B fell is 1:4.
The value of the peak power will be 50 W. The peak power is found as two times of the average power. Option C is correct.
<h3 /><h3>What is average power?</h3>
Average power is a ratio of total work done by the body to the total time. Its unit is the watt. It is also defined as the rate of total work done by the body.
The given data in the problem is;
Average power = 25 W
Peak power = ?
The peak power is found as;
Peak power = 2 × average power
Peak power=2×25
Peak power = 50 W
Hence, the value of the peak power will be 50 W.

Answer:
Dwarf Planet (Other celestial Object)
Explanation:
Pluto has characteristics similar to both terrestrial and Jovian Planets. It has rocky surface like terrestrial planets but lies far away from the Sun like Jovian planets. It is much smaller than the planets of the solar system. It is round in shape and orbits the Sun in highly eccentric path. It has 5 moons. It is composed of rocks and ice.
Pluto lies beyond the orbit of Neptune in the Kuiper Belt. Many more similar objects similar to Pluto were discovered in the Kuiper Belt which led to its demotion from a planet to a dwarf planet in 2006.
