Abody in flight explodes into three equal portions. one portion continues along the original line of flight. the other two go off in directions each inclined at 60 to the original path. the energy released in the explosion is twice as great as the kinetic energy possessed by the body at the time of explosion. determine the kinetic energy of each fragment immediately after the explosion.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the answer is 12 as i may remember

3. dark matter

empty space could also be a simple vacuum
