Along metal cylinder with radius a is supported on an insulating stand on the axis of a long, hollow, metal tube with radius b. the positive charge per unit length on the inner cylinder is l, and there is an equal negative charge per unit length on the outer cylinder. (a) calculate the potential v1r2 for (i) r 6 a; (ii) a 6 r 6 b; (iii) r 7 b. (hint: the net potential is the sum of the potentials due to the individual conductors.) take v = 0 at r = b.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
