Radium has 88 protons in its nucleus and has no stable isotopes (all are radioactive). Suppose one could break apart such a nucleus to form two equal sized nuclei with 44 protons each that are at rest and just touching after the fission process. Assume each has a radius of 5.5×10−15. Calculate the kinetic energy that each of the nuclei will have when they are very far apart.

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

the ima (higher than 1m) will be greater than the ima with the height of 1m.
