Question

For a seconds pendulum caliberated at 20⁰ C, operated at 30⁰C. Find the gain or loss in one day​

Answer 1

◆ Answer-

36.288 s

◆ Explanation-

# Given-

α = 1.2×10^-5 /°C

T1 = 20 °C

T2 = 30 °C

t = 1 week = 604800 s

# Solution-

Change in temperature is

∆T = T2 - T1

∆T = 30 - 20 = 10 °C

Time gained by clock is calculated by formula-

∆t = 1/2 α∆Tt

∆t = 1/2 × 1.2×10^-5 × 10 × 604800

∆t = 36.288 s

Therefore, the clock will gain 36.288 s.
