Determine the magnitude, fda, acting along member da, due to the applied force f=10.0 iâ20.0 j+27.2 k n.
VashaNatasha [74]

Force vector is given as

F = 10\hat i + 20\hat j + 27.2\hat k

now we need to find the magnitude of this force

as we know that

F_x = 10

F_y = 20

F_z = 27.2

so here we will find the net force

F_{net} = \sqrt{F_x^2 + F_y^2 + F_z^2}

F_{net} = \sqrt{10^2 + 20^2 + 27.2^2}

F_{net} = 35.2 N

so it is having magnitude as 35.2 N

Answer: a. air pollution

c. hazardous wastes

d. potential reactor accident

e. water pollution

A nuclear energy is produced in a thermal power plant. A nuclear energy is produced in a nuclear reactor. In nuclear reactor nuclear fission reactions takes place in which an atoms absorbs energy from radiations and undergo fission and produces energy in the form of high intensity radiations along with heat. Although the fission reactions takes place in a nuclear reactor in a controlled way so that the radiation may not leak out from the reactor. The accidentally leak out radiations or explosion or bursting of the reactor due to uncontrolled thermal energy production can result in air pollution as the leak out air will cause bursting effects which will contaminate the air.

The nuclear waste are radioactive and are non-biodegradable these wastes are disposed off deep in geospheres and in water. They have potential to contaminate both land and water. Radioactive wastes can cause mutations in the genome of the organisms exposed to these wastes which generate deadly diseases and disorders.  Therefore, these wastes are hazardous.
