Answer:
<h2>288 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 12 × 24
We have the final answer as
<h3>288 kg.m/s</h3>
Hope this helps you
Answer:
7200N
Explanation:
Centripetal force is directly proportional to the product of the mass and the square of the velocity and inversely proportional to the radius given.
<span>Nuclear power plants produce radioactive
waste that must be stored properly. It is very impossible for a nuclear power plant
to have no waste at all since lots of chemicals are used to create the process
as it gives energy to other machines. Nuclear energy can be used to power all
of the above choices. Radioactive waste can not be released into local water
supplies since the wastes are very radioactive and may cause mutation to the
fishes and bioaccumulation which will affect humans as well. It will also cause
air pollution if the chemicals are not stored properly.</span>
Answer:
v = 10 m/s
Explanation:
Given,
Length of the vine, l = 36 m
Angle of inclination = 31.0◦ with the vertical
acceleration due to gravity = 9.81 m/s²
Using Conservation of energy
KE = PE
v = 10 m/s
Hence, the speed of the swing is equal to 10 m/s
