Which of the following sources of energy is/are exhausible? i. Solar ii. Fossil fuels iii. Tidal power
Answer Details
The term "exhaustible" means that the source of energy is finite and will eventually run out. Solar energy is considered inexhaustible because it comes from the sun and will be available as long as the sun exists. On the other hand, fossil fuels, such as coal, oil, and natural gas, are considered exhaustible because they are finite resources and will eventually be depleted. Tidal power is also considered inexhaustible because it relies on the gravitational pull of the moon and the sun on the Earth's oceans, which will continue as long as the Earth continues to orbit the sun.
Therefore, the answer is: ii and iii only.
