During the diving when a diver jumps off from platform he brings her knees and arms closer to the body
This is because when diver is in air he don't have any torque about his center of mass which shows that angular momentum of his body will remain constant during his motion in air
Now we can say product of his moment of inertia and his angular speed will remain constant always
So here if we decrease the moment of inertia of the body during our motion then angular speed will increase so that product will remain constant
and this is what the diver use during his diving
so correct answer will be
<u><em>It decreases her moment of inertia.</em></u>
C.) A thunderstorm
That’s the Answer
A stratovolcano is a conical volcano consisting of layers of solid lava flows mixed with layers of other rock.
A cinder cone volcano doesn’t have any horizontal layers, and is instead a steep conical hill of tephra that accumulates around and downwind from the vent.
1.56 x 10^12 electrons electrons should be removed.
What are electrons ?
The subatomic particles that revolve around an atom's nucleus are called electrons. They are smaller than protons or neutrons and have a negative charge. They are actually 1,800 times smaller. They also convey electric current.
Radius = 0. 300 m
Potential = 7.50 kV = 7.5 x 10^ 3 V
We kniw,
(Electric Potential) V = ke q/r
and q= ne
Therefore, n= Vr/ ke e
now substituting the values we get,
n= 1.56 x 10^12 electrons

<span>Objects X and Y are in a strong magnetic field.
Both objects are removed from the magnetic field, after which
the magnetic domains in Object X remain unchanged while the
domains in Object Y go from being aligned to becoming random.
Object X is a permanent magnet because it retains the alignment
of the domains, while object Y is a temporary magnet because the
domains became random. (B)</span>
