Answer:
c. Fission and fusion are two processes that release very little amounts of energy.
Explanation:
This statement is false. In fact, both fission and fusion are processes which release very large amounts of energy. The statement can be rewritten as it is true as follows:
"Fission and fusion are two processes that release very large amounts of energy."
Fission occurs when a large nucleus break apart, splitting into smaller nuclei, while fusion occurs when two light nuclei combine together into a larger nucleus. In both cases, the mass of the reactants is larger than the mass of the final products, so some of the mass has been converted into energy, according to Einstein's equation:
where
E is the energy released
is the mass lost in the process
c is the speed of light
Since c is a very large number (), we see that even a very small mass
causes the released of a huge amount of energy, so both fission and fusion release large amounts of energy.
Explanation:
Formula for the electric field due to the infinite sheet of charge is as follows.
E =
where, = surface charge density
Now, formula for electric force acting on the proton is as follows.
F = eE
where, e = charge of the proton
According to the Newton's second law of motion, the net force acting on the proton is as follows.
F = ma
a =
=
=
According to the kinematic equation, speed of the proton in perpendicular direction is as follows.
=
=
= 683.974 m/s
Hence, total speed of the proton is as follows.
v' =
=
=
= 1178.73 m/s
Therefore, we can conclude that speed of the proton is 1178.73 m/s.
