When the u-235 nucleus is struck with a neutron, the ce-144 and sr-90 nuclei are produced, along with some neutrons and beta par ticles. how many neutrons are emitted?
1 answer:
Answer: 2 (2 neutrons are produced). Explanation: 235 + 1 = 236 144 + 90 = 234 236 - 234 = 2 unit masses on the right side which are the 2 neutrons that are produced along with the Ce and Sr.²³⁵U + ¹n → ¹⁴⁴Ce + ⁹⁰Sr + 2 ¹n

Answer:
2.45Joules
Explanation:
since kinetic energy is K.E.=1/2m
lost in potential energy is gain of kinetic energy
mgh=1/2mv^2
9.8*2*0.5=v^2
v=
now k.e. = 0.5*m*
