16th question please

Answer 1

The time is given by the distance travelled by the light divided by the speed of light.

$\longrightarrow\sf{t=\dfrac{s}{v}}$

The distance travelled by the light to pass through the nucleus is equal to the diameter of the nucleus.

$\longrightarrow\sf{s=1.56\times10^{-16}\ m}$

Speed of light is,

$\longrightarrow\sf{v=3\times10^8\ m\,s^{-1}}$

Hence time is,

$\longrightarrow\sf{t=\dfrac{1.56\times10^{-16}}{3\times10^8}}$

$\longrightarrow\sf{\underline{\underline{t=5.2\times10^{-25}\ s}}}$
