Answer:
The change on the second particle is
.
Explanation:
The period of revolution of the particle in the magnetic field is given by the formula as follows :

It is given that the magnetic field is uniform. The mass of the second particle is the same as that of a proton but thecharge of this particle is different from that of a proton.

If both particles take the same amount of time to go once around their respective circles. So,

So, the change on the second particle is
.
D. Destructive interference. An easy way to think about it is the waves are opposite each other, so they essentially cancel each other out, or make an effort to.
I would say D. because you round to the nearest whole number and 0.04 is way less than 0.5 which is a good rounding up number.
Because it does not produce waste, thus it doesn't harm the environment. also renewable sources are infinite.
Answer:
friction force
Explanation:
force of friction is opposite to the force applied it resist the motion
