Answer 1

So, there are 6 pendulums mentioned here, so Kinetic energy is equal to $\frac{1}{2} mv^{2}$= mgh, and speed is V = $\sqrt{2gh}$. so, the larger to the smaller ranking is, 1 = 5 > 2 = 6 > 4 > 3.

What is Kinetic energy?

Motion is created by kinetic energy. According to the fundamental definition of energy as the capacity to do work, the SI unit for energy is the joule, which is equal to one-newton × one meter. An object's motion-related energy is known as its kinetic energy.

What is Pendulum?

The body is suspended from a fixed point and able to swing back and forth due to gravity. Pendulums are used to regulate clock movement because the time interval for each complete oscillation, known as the period, is constant. T = 2 Square root of L/g is the formula for calculating the period 'T' of a pendulum, where L is the length of the pendulum and g is the acceleration due to gravity.

Hence, the larger to smaller ranking 1 = 5 > 2 = 6 > 4 > 3.
