Nuclear reactions result in tremendous amounts of
a.
uranium.
b.
energy.
c.
fission.
d.
mass.

The correct answer is energy.

Explanation:

There are two types of nuclear reactions: Nuclear fission and Nuclear fusion.

Nuclear fission is a process in which the bigger nucleus splits into the daughter nuclei with huge amount of energy.  Atomic bomb is based on nuclear fusion. Here, the energy is originated from the splitting of uranium atom in the nuclear fission.

Nuclear fusion is a process in which the lighter nuclei fuse to give heavier nuclear with tremendous amount of energy.

Nuclear fusion takes place in the Sun.

Therefore, Nuclear reactions result in tremendous amounts of energy.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
