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>

Explanation:
The frequency of sound waves received by the microphone influences the output or pitch of the sound obtained from the microphone.
The higher the frequency of the sound received by the microphone, the higher the output of the microphone and vice versa. This is because, the higher the frequency of sound, the higher the oscillations produced and the greater the output of the microphone.
The rise and fall in the pitch of sound waves as the frequency of sound waves varies is called inflection.
Answer:
Mass of the solution = 54.75 g
Explanation:
Mass of solid dissolved = 4.75 g
Mass of the solution = Mass of solid dissolved + Mass of water.
Mass of water = Volume x Density
Volume = 50 mL = 50 cm³
Density = 1 g/cm³
Mass of water = 50 x 1 = 50 g
Mass of the solution = 4.75 + 50 = 54.75 g
Answer:
An object is in motion when its distance from another object is changing. ... A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. You assume that the reference point is stationary, or not moving.
Explanation:
climate change affects: earths atmosphere
A warming atmosphere affects more than just air temperatures
<u>causes wild weather such as</u>
droughts are becoming more common and intense
rainstorms are also becoming more powerful
it provokes dangerous floods as well.
