The ray diagram given below gives the principle of a compound microscope. The object is mounted on the stand below the microscope tube. The objective lens forms a real, inverted and magnified image (I 1 ) of the object. The image I 1 acts as an object for the eye piece. The posi..

As the current in the primary varies, the flux linked with P 1 P 2 and hence S 1 S 2 , changes . If N p is the number of turns in P 1 P 2 , and E p is the alternating EMF fed to P 1 P 2 at instant t under ideal conditions; Self induced EMF in P ..

. But when sides of the coil interchange their positions, then the two commutator half rings R 1 and R 2 automatically change their contacts from one carbon brush to the other. Due to this change, the current keeps flowing in the same direction. Thus a DC generator supplies a cu..

To start with, suppose the plane of the coil is perpendicular to the plane of the paper in which the magnetic field is applied, with AB at the front and CD at the back, the flux linked with the coil is maximum in this position. As the coil rotates clockwise, AB moves inwards and CD moves outwards...

When pure and dry H 2 gas is passed through the inlet tube, a part of the gas gets adsorbed and the excess bubbles out through the perforations. Between the H 2 gas absorbed on the surface of the metal and H + of the solution, an equilibrium is established and an electrical double layer of oppo..

. According to equation of motion v 2 = v 0 2 + 2 a x d ______(2) Substituting (1) in (2), we get Hence, the work done by the force on the ball is equal to the energy transfer. Work done due to the force is W = F x d. Therefore, to calculate work, w..

SI Unit of Work - W = F x S SI unit of F is N and that of S is m [N = newto..

SI Unit of Work - W = F x s SI unit of F is N and that of s is m [N=Newton] 1Nm is defined as 1 joule. i.e., 1 joule = 1..

In many cases when we pull or push an object, we find that force and displacement are not in the same direction. Let a constant force F acting on a body produce a displacement S as shown in the figure. Let q be the angle between the directions of the force and displacemen..
