C because when the part gets out of the probe it would no longer stay contacted
charge = current x time = 0.5x 20=10Coulombs
<span>As the temperature goes down, the chaotic motion (velocity) of atoms start decreasing. If the temperature hits the absolute zero (which, in reality, is impossible to achieve), the atoms of the body would freeze, making the body still and stiff. One thing to note here is that the atoms do not get destroyed when the temperature reaches the absolute zero. That is the reason why the object can still be seen when it is at absolute zero.</span>
It increases, because the centripetal acceleration is inversely proportional to the radius of the curvature.
Hopr it helps :)
