What is the source of the energy released in fission and fusion reactions?
a) mass converted to energy
b) breaking of chemical bonds
c) formation of alpha particles
d) formation of new chemical bonds

A) mass converted to energy

Explanation:

Nuclear fusion occurs when two light nuclei fuse together, forming a heavier nucleus. In the process, the mass of the final nucleus is smaller than the total mass of the initial nuclei, so part of the initial mass has been converted into energy. An example of nuclear fusion is the fusion of two nuclei of hydrogen into helium, a process that occurs in the core of the stars.

Nuclear fission occurs when a heavy nucleus breaks into two or more smaller nuclei. In the process, the total mass of the final nuclei is smaller than the mass of the initial nucleus, so part of the mass has been converted into energy. An example of nuclear fission is the fission of the uranium, which occurs in nuclear power plants.

In both cases, the energy released in the process can be calculated using Einstein's equation:

where

is the difference in mass between final products and initial nucleus/nuclei

c is the speed of light

a

Explanation:

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
