The length of a simple pendulum is 0.760 m, the pendulum bob has a mass of 365 grams, and it is released at an angle of 12.0o to

Allushta [10]

Answer:

0.572 Hz

Explanation:

given,

length of simple pendulum, l = 0.76 m

mass of the bob, m = 365 g = 0.365 Kg

angle made from the vertical, = 12°

frequency, f = ?

$f = \dfrac{1}{2\pi}\sqrt{\dfrac{g}{L}}$

$f = \dfrac{1}{2\pi}\sqrt{\dfrac{9.8}{0.76}}$

$f = \dfrac{1}{2\pi}\times 3.59$

f = 0.572 Hz

The frequency at which pendulum vibrates is equal to 0.572 Hz

Marina86 [1]

Answer:

$2.88*10^{8} m/s$

Explanation:

The speed of light is given by

$c=\frac {2d}{t}$ and $t=\frac {\theta}{\omega}$ hence

$c=\omega\frac {2d}{\theta}$

Speed of light is given by

$c=900\times 2\pi(\frac {2\times 10}{\frac {2\pi}{2*800}}})=2.88*10^{8} m/s$
