Explanation:

t = 2\pi \sqrt{l \div g}

T= 2π√.49/9.8 = 2π√1/20

Answer:

The time period of a simple pendulum of length 0.49, when g = 9.8\ m/s^2  will be  1.4042 s

Explanation:

Let T be the time period of a simple pendulum and l be the length of the pendulum

Then time period is given by the expression,

T = 2\pi \sqrt{\frac{l}{g} }       ...(1)

Where g is the acceleration due to gravity.

In the question, it is given that,

l = 0.49 m      g = 9.8\ m/s^2

Then substitute these values into equation(1),

T = 2\times 3.14\times \sqrt{\frac{0.49}{9.8} } \\

So we get,

The time period of the simple pendulum, T =1.4042 s
