Physics Questions

The photoelectric effect pointed to the particle properties of light, which had been considered to be a wave phenomenon. Particles like electron and protons have both particle like and wave like behavior. Thus, according to de Broglie, all the material particles in motion possess wave characteristics. Although the dual nature of matter is applicable to all material objects but it is significant for microscopic bodies only.

The frequency of a sound wave is determined by the amplitude of the wave. As amplitude of the wave is high the frequency of the wave will also be high.

Both when accelerated through a potential difference of 100KV, they will have the same energy. The mass of the electron is less than the mass of a proton, hence it will move faster(momentum).

The odometer or the odograph is an instrument used to indicate the distance travelled by the vehicle.

An ideal gas cannot be liquified because forces between the molecules are negligible.

If an object moves with some velocity that means the magnitude and direction of the object changes i.e, the object moves with some acceleration. Hence, if the object moves with constant velocity, no change in direction and magnitude of speed i.e, no acceleration = 0 acceleration.
