In nuclear fission, a nucleus of uranium-238, containing 92 protons, can divide into two smaller spheres, each having 46 protons and a radius of 5.90 ✕ 10-15 m. what is the magnitude of the repulsive electric force pushing the two spheres apart?

Explanation:

As we know that electrostatic repulsion force between two protons is given as

now we know that

now the distance between the two atoms is same as the distance between two center

now from above formula we have

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.
