True,
Explanation: because it’s the same reason that lighting touches the ground/ goes up to the sky, because it is trying to balance out its charges
It would move to the right because the force is being applied from the left.
wavelength = d / number of Oscillation
this implies that wavelength = 30/3= 10
number of wavelengths = 10
Answer: Entropy is basically a thermodynamic quantity that tells the randomness of a system or as said in the question tells us a measure of the disorder of the system. The second law of thermodynamics states that a closed system has entropy which may remain constant
No, gravity pulls every object with the same force irrespective of its shape, size place etc.
Therefore the force of gravity on the iron and wooden piece of same mass is same. Also the force of gravity is same on the crumpled piece of paper as that of plain paper.
Force of gravity is always same.
