Answer:
sound wave-electrical wave-radio wave
Renewable source means that it can never run out or run out in a long time. In this case the sun is expected to shine for about five billion years because of the high amount of hydrogen that is stored in its core. So the answer should be "The sun is continuously releasing energy". This answer is the best because there are many other renewable resources on earth that can cause pollution.
Answer:
As we keep on increasing the radius the value of the gravitation force of attraction decreases and as we decrease the radius the gravitation force increases.
Explanation:
Like the coulombs law of electrostatics, the law of gravitation also depends inversely on the square of the value of r. Therefore, as we keep on increasing the value of r the value of the gravitation force decreases and as we decrease the value of the r the value of gravitation force increases.
Gravitation Force=
Coulombs's Law=
