At what rate must uranium 235 undergo fission by neutron bombardment to generate energy at a rate of 154 w (1w = 1j/s)? assume each fission reaction releases 200 mev of energy. how many billions of fissions per second are required? use 1 ev = 1.6 * 10-19 j. enter an integer.

To develop this problem we simply have to perform conversions per second to know the amount of fission that are made. A simple mathematical calculation that starts from:

Watts is the energy invested over time therefore

According to the statement there is a release per second of 200MeV so the number of Fisions per second would be subject to

Therefore there are 28593.75*10^{9} Fissions per second.

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
