When a Fortin barometer is taken to a high mountain, the mercury falls in the tube because atmospheric pressure becomes lower there. Reduced atmospheric pressure at higher altitudes causes the mercury column to drop in the barometer tube, indicating the ...

It is more difficult to breathe on mountains than on plains because as altitude increases, air pressure decreases, and the need for oxygen increases. Reduced air pressure at higher altitudes makes it harder for lungs to take in sufficient oxygen, ...
Due to the increase in the height of the atmosphere, the size of the balloon will decrease. As the balloon ascends, the atmospheric pressure decreases, causing the gas inside to expand, stretching the balloon’s material and reducing its size. Therefore, ...
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.
