$$T = 2\pi \sqrt{\frac{l}{g}}$$

where $l$ is the length of the string in meters (m) and $g$ is the acceleration due to gravity in meters per second squared ($\mathrm{m/s^2}$).

T = 2\pi \sqrt{\dfrac{l}{g}}

$$g \approx 9.8 \, \mathrm{m/s^2}$$

9.8 , m/s^2

$$T = 2\pi \sqrt{\frac{l}{g}}$$

Substitute $l = 1 \, \mathrm{m}$ and $g = 9.8 \, \mathrm{m/s^2}$:

$$T = 2\pi \sqrt{\frac{1}{9.8}}$$

Calculate the fraction:

$$\frac{1}{9.8} \approx 0.1020$$

Take the square root:

$$\sqrt{0.1020} \approx 0.3194$$

Multiply by $2\pi$ (using $\pi \approx 3.142$):

$$2 \times 3.142 \times 0.3194 \approx 6.284 \times 0.3194 \approx 2.01 \, \mathrm{s} \approx 2.0 \, \mathrm{s}$$

$$T = 2\pi \sqrt{\frac{l}{g}}$$

Substitute $l = 0.5 \, \mathrm{m}$, $g = 9.8 \, \mathrm{m/s^2}$:

$$T = 2\pi \sqrt{\frac{0.5}{9.8}}$$

Calculate the fraction:

$$\frac{0.5}{9.8} \approx 0.05102$$

Take the square root:

$$\sqrt{0.05102} \approx 0.2259$$

Multiply by $2\pi$:

$$2 \times 3.142 \times 0.2259 \approx 6.284 \times 0.2259 \approx 1.42 \, \mathrm{s}$$
