Answer:
Option B
3
Explanation:
The two dimensions have the following significant numbers
4.56- 3 significant numbers
5.668- 4 significant figures
When responding, we give area as per the most precise number given hence the smallest (most precise) significant figures in these two numbers is 3. Therefore, the area will be given to 3 significant figures ie
4.56*5.668=25.84608 square meters
Area=25.8 square meters
(10 seconds) / (2 cycles) = (10/2) (sec/cycle) = 5 seconds.
That's the pendulum's period.
Frequency = 1 / (period) = 1/5 per second = 0.2 Hz.
