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.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
