The force ultimately responsible for mass movement

In a qualitative way, the tendency of undisturbed objects to stay at rest or to keep moving with the same velocity is called _________.

Calculate the frequency (in Hz) of a sound wave of wavelength 5 m travelling with a speed of 360 m/s.

A wooden block of mass m1 kg accelerates at m/s when a force of 5 N acts on it. Another block of mass m2 kg accelerates at 20 m/s when the same force acts on it. If both the blocks are tied together and the same force acts on their combination, the acceleration will be about

Consider a hypothetical planet with a mass equal to half that of Earth and radius is one-third that of Earth. If g is the acceleration due to gravity on Earth, the acceleration due to gravity on the planet will be

Who first determined the value of G (gravitational constant)?

Which of the following waves cannot be polarised?
