The magnetic flux density B( in tesla ) inside the solenoid and parallel to its axis is given by the expression B= permeability of free space x n x I, where n is the number of turns per metre length of the solenoid my question is so for example, if n = 100turns in 1m and I = 2Ampere...

Yes sir it's part of a longer qn about a ball on ground level being kicked onto the wall. Nonetheless can u help me with Q1 and 3 :) thanks

hey are your answers in (a) and (b) correct? it's perfectly inelastic collision right? shouldn't it be 45x8 + 31x(-11) =(45+31)(Y), where Y is +0.25?

The ball of mass 0.45kg hits the wall when it reaches maximum height of1.8m. The ball is incident witha horiziontal velocity of 6.6m/s and rebounds in a horizontal direction with a velocity of 5.2m/s. the ball is in contact with the wall for 0.22s. State and explain whether the collision with...

hello there! your help is really appreciated. 1.For the Ruther alpha-particle scattering experiment, how come we are only concerned with the nucleus of the gold with repulsion on the alpha particle? what about the electrons in gold? Don't they attract the alpha particle? 2. To calculate...
