Asolenoid of radius 2.0 mm contains 100 turns of wire uniformly distributed over a length of 5.0 cm. it is located in air and carries a current of 2.0 a (i) using ampere's law, calculate the magnetic field strength b inside the solenoid 4 marks] (ii) draw a diagram clearly showing the direction of current flow in the solenoid and the direction of the magnetic field.

Describe the function of the endomembrane system? what organelles are involved?

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.
