“if there is an black hole then how does it so much of gravitational pull to never even let go of the light tht passes by its surface…????”
Say True or False; An object on the Moon weights 1/6 of what it weights on the Earth. Therefore, the object has less inertia on the Moon.( Justify your answer)
Answer: The statement is false.
Inertia depends on mass and not on weight. The weight on moon is less not because of a decrease in mass, but due to the decrease in the acceleration due to gravity on the surface of moon.
Inertia depends on mass and there is no change in mass when a body is taken to moon. Therefore the inertia of a body is same on moon as that on earth or anywhere else in the universe, even in a gravity free space.
How does surface tension act? What is basic cause?
Answer: Surface tension is the property of a liquid by virtue of which its free surface behaves like a stretched elastic membrane.
When a blade is carefully kept on a liquid surface, it floats; but it sinks if it is dropped carelessly.
You can see below the photograph of a drop of water falling on water surface. Can anyone explain the observation?
