Hi there! :)
In the solar system, we can categorize the planets as such:
Inner planets: Mercury, Venus, Earth, Mars
Outer planets: Jupiter, Saturn, Uranus, Neptune
The Inner planets are the only planets that consist of solid rock. They also do not have rings and have impact craters due to their early formation.
In comparison, all of the outer planets are primarily made up of gaseous material and contain rings.
Therefore, the correct choice is B.
Answer: (B). Solar cell B, because it generates more power.
Explanation:
Given that,
For solar cell A
Energy = 100 Joules
Time = 3 minutes = 180 sec
Power of cell A
Power = Energy/Time
For solar cell B
Energy = 200 joules
Time = 5 minutes = 300 sec
Power of cell B
Power = Energy/Time
Hence, Solar cell B, because it generates more power.
