When you exercise, your body naturally sweats in order to cool itself off. The sweat has a definite amount of salt in it, which is why your sweat tastes salty. Also, The more you sweat, the more salt that leaves your body.

The so-called "velocity-time" graph is actually a "speed-time" graph. At any point
on it, the 'x'-coordinate is a time, and the 'y'-coordinate is the speed at that time.
'Velocity' is a speed AND a direction. Without a direction, you do not have a velocity,
and these graphs never show the direction of the motion. It seems to me that it would be
pretty tough to draw a graph that shows the direction of motion at every instant of time,
so my take is that you'll never see a true "velocity-time" graph.
At best, it would need a second line on it, whose 'y'-coordinate referred to a second
axis, calibrated in angle and representing the 'bearing' or 'heading' of the motion at
each instant. The graph of uniform circular motion, for example, would have a straight
horizontal line for speed, and a 'sawtooth' wave for direction.
Answer:
Option A - the moment of inertia of the system decreases and the angular speed increases.
Explanation:
The moment of Inertia of merry- go-round spins is
I = + mr²
ζ = I
ζ =( + mr²)
= ζ / ( + mr²)
where is the angular speed
increases when the moment of inertia decreases
Therefore, it is true to say that the moment of inertia of the system decreases and the angular speed increases.
V=IR
The more V, the more I
