The graph between variation of resistance of a wire as a function of its diameter keeping other parameters like length and temperature constant is
Which of the following graphs represent the variation of magnetic field \( B \) with perpendicular distance \( r \) from an infinitely long, straight conductor carrying current?
The anode voltage of a photocell is kept fixed. The frequency of the light falling on the cathode is gradually increased. Then the correct graph which shows the variation of photo current \( I \) with the frequency \( f \) of incident light is
It refers to the rapid increase in the population of an area among human beings. Furthermore, it is a situation where the economy is not capable of coping with the increasing demand of its population. Population explosion refers to the number of people that live in an area. It is a major issue for developing countries. Also, the government is not taking proper measures to control this problem
The cause of the population explosion includes many factors and reasons. These includes:
