<span>In order to make 4 complete revolutions in 4 seconds, the wheel must have a constant angular acceleration of 144° (or 2.5 radians) per square second, hence after 8 seconds the wheel will have made 14,4 revolutions, or 5184° in total.</span>

OLga [1]
E the temperature of a substance. Water has a very high specific heat. That means it needs to absorb a lot of energy before its temperature changes. Sand , on the other hand, have lower specific heats. This means that their temperatures change more quickly. When the summer sun shines down on them, they quickly become hot.

How does the charge of a particle affect the direction in which the particle is deflected in a magnetic field?
AlexFokin [52]

This is simply because the positively charged particles will go to negative end of magnetic field, and the negatively charged particles will go to positive end of magnetic field, and vice versa.

This happens due to the fact that the positive end is both repelled by the positive part of the field, at the same time, attracted by the negative end.
