Question

how pendulums oscillation time depends upon temperature?

Answer 1

yes the pendulum oscilation depends on temperature ..when the temperature in atmosphere is high the pendulum oscillations are more bcoz of less humidity.
if temperature is low the humidity is more so we say that pendulum oscillation depens upon temperature

hope this help u

Answer 2

As we know that if temperature is high then the humidity will also be high. And we know that the speed of pendulum is directly proportional to humidity. So this means as more the humidity, the more the speed of pendulum i.e. the more the temperature, the more the speed of pendulum..
So, due this , the speed of oscillation of pendulum depends upon temperature
