Hooke’s principle is related to elasticity. It states that the force needed to extend or compress a spring by some distance is proportional to that distance. This principle is fundamental in understanding the behavior of elastic materials under deformation and ...

The kinetic energy of a particle is given by the formula K = p²/2m, where p represents momentum and m represents mass. This formula describes the relationship between momentum, mass, and kinetic energy for a particle in motion.

When a pendulum is taken to the moon, its time period increases. This is because the acceleration due to gravity on the moon is weaker than on Earth. As a result, the pendulum swings slower, leading to a longer time ...

When the length of a pendulum is quadrupled, its time of swing increases proportionally. Therefore, the correct answer is option [D]: it becomes four times. This relationship is described by the formula T = 2π√(L/g), where T is the time ...

If the length of a simple pendulum is increased by 4%, its time period will increase by approximately 2%. This relationship arises because the time period of a pendulum is directly proportional to the square root of its length. Therefore, ...

Pendulum clocks become slow in summer because the length of the pendulum increases due to thermal expansion, causing the time taken for one oscillation to increase. This change in length affects the clock’s timing mechanism, resulting in slower timekeeping during ...

The time period of a pendulum depends on its length. The longer the length of the pendulum, the longer the time it takes to complete one oscillation. Mass, temperature, and time do not affect the time period of a pendulum.

The fraction of the Earth’s gravity that is closest to the Moon’s gravity is 1/6. The gravitational acceleration on the Moon’s surface is approximately 1/6th of that on the Earth’s surface, making it the closest fraction among the options provided.

Skating on ice shows that on increasing the pressure, the melting point of ice decreases. The pressure applied by the skater’s weight lowers the melting point of the ice, causing it to briefly melt and form a thin layer of ...

Viruses are considered non-living because they can crystallize. Unlike living organisms, viruses are not cellular and can exist in a crystalline form outside of host cells, remaining inert until they infect a host to reproduce.
