Suppose a nucleus of 93X236 fissions into two fragments whose mass ratio is 0.37:0.63. With the aid of the drawing, estimate the energy (in MeV) released during this fission. The drawing Shows A large. The A1 smaller the A2, A2 is nearly double the size of A1

If a bow with a draw weight of 60 kilograms were to fire at someone 5 meters away but the user had to roll first before drawing back and firing two arrows. Would the target have enough time to dive for cover behind a rock?

Suppose a nucleus of 93X236 fissions into two fragments whose mass ratio is 0.37:0.63. With the aid of the drawing, estimate the energy (in MeV) released during this fission. Ive treied to do this problem but i keep getting the wrong answer. I keep getting 164.253 MeV
