Answer:

Explanation:

For the chain reaction in a nuclear fission to sustain , the size of nuclear material must be of some minimum magnitude ( called critical mass ) other wise after some time the chain reaction ceases to continue. The reason is that too many of neutrons that are instrumental in sustaining the reaction starts leaking out of the surface of fissionable material . This results in the stoppage of the reaction after some time.

Answer:

$\omega=7.16*10^{-13}\frac{rad}{s}$

Explanation:

The angular speed is given by:

$\omega=\frac{v}{r}$

Here v is the linear speed and r is the radius of the circular motion. The height of the tower is equal to the radius of the circular motion of the top of the tower, since is rotating about its base. We need to convert the given linear speed to $\frac{m}{s}$ :
