A ammeter. I hope this helps.
Answer:

Explanation:
As we know that it will have constant torque on it
so the acceleration of the ball will be constant so here we can say that we can use kinematics equation



so we have


now we know that



so we know that

here we know that
diameter = 0.72 m
so radius (R) = 0.36 m


To calculate the horizontal distance traveled by the ball, we first calculate the total time it takes to reach the ground as follows:
t = √[2y/g] = <span>√[2(0.55) / 9.81]
t = 0.33 s
The horizontal distance would be
</span><span>X = Vx*t = 1.2*√[2*.55/9.8] = 0.4 m
</span>

The Earth has cooled for the past 2 million years.
If you take a fluid (i.e. air or water) and heat it, the portion that is heated usually expands. The same mass takes up more volume and as a consequence the heated portion becomes less dense than the portion that is<span><span> not heated.</span> </span>
