Question

How will the clock with a pendulum on a metal rod change: a) if the temperature rises, b) during the ascent of the mountain, c) when moving from Toronto to Miami?

Answer 1

a) When the temperature increase, the length of the pendulum gets longer - the frequency decreases, the period becomes longer, the clock will start to lag behind.
b) When climbing a mountain, the acceleration of free fall decreases - the frequency decreases, the period becomes longer, the clock will start to lag behind.
с) When you move to the south the acceleration of gravity (due to centrifugal force) will decrease - the frequency decreases, the period becomes longer, the clock will start to lag behind.
