A clock pendulum having coefficient of linear expansion, α = 9 × 10 - 7 / C o has a period of 0.5 s at 20 o C . If the clock is used in a climate where the temperature is 30 o C , how much time does the clock lose in each oscillation? g = c o n s t a n t

Question

A clock pendulum having coefficient of linear expansion, α = 9 × 10 - 7 / C o has a period of 0.5 s at 20 o C . If the clock is used in a climate where the temperature is 30 o C , how much time does the clock lose in each oscillation? g = c o n s t a n t, 2.5 × 10 - 7 s, 5 × 10 - 7 s, 1.125 × 10 - 6 s, 2.25 × 10 - 6 s
