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
Options
- A2.5 × 10 - 7 s
- B5 × 10 - 7 s
- C1.125 × 10 - 6 s
- D2.25 × 10 - 6 s
Correct answer
D. 2.25 × 10 - 6 s
Step-by-step solution
∵ d T T = 1 2 ∙ α ∝ d T d T = 1 2 1 2 9 × 10 - 7 10 d T = 2.25 × 10 - 6
