Table given below shows the current (I) voltage (V) relationship of a device.

Draw V-I graph. With the help of the graph explain whether the device is showing ohmic or non-ohmic behaviour

(a) The figure shows the position time graph of a body moving along a straight line. i) Draw the velocity - time graph of the body.

The picture given below shows the technique used for generating multiple copies of the gene of interest. (a) What is the technique called? (b) Name the reactions at step I, step II and step III. (c.) Explain the principle underlying this techniques of DNA amplification.

When photons incident on a metallic surface electric current is produced. The work function of a metal is given by [phi_0 = hc / lambda_0 = h(upsilon_0 )] ,where (lambda_0, c , h , upsilon_0) have their usual meaning The graph given below shows the variation in stopping potential with frequency upsilon of the incident radiation of the materials A and B. : Which material has higher work function?

Ampere's theorem helps to find the magnetic field in a region around a current carrying conductor:-Draw a graph showing the variation of intensity of magnetic field with the distance from the axisof a current carrying conductor

If the ammeter shows a current I ampere on applying a potemtial difference V across the resistor of resistance R omega . Current I = Q/t . Then the charge that flows through the conductor in' t ' second, Q = ……………. Coulomb .
