A tent is in the shape of a cylinder surmounted by a conical top.If the height and diameter of the cylindrical part are 2.1m and 4 m respectively,and the slant height of the top is 2.8 m,find the area of the canvas used for making the tent.Also find the cost of the canvas of the tent at the rate of Rs.500 per m^2 (Note that the base of the will not be covered with canvas).

The horizontal distance between two towers is 30 metres.The top of one makes an angle of depression of 30^@ at the top of the other.If the height of the first tower is 150 meters,find the height of the second tower.

Two bodies having masses 1g and 4g are moving with equal K.E find the ratio of their linear momentum.

Two spherical balls are charged with 1.2 and 4.8 coulomb of charges. The distance between their centre is 120 cm. Find out the point where the forces neutralise each other.

Take a sheet of paper. Measure its area. Pile up such sheets of paper of same size to make cuboid. Measure the height of this pile. Find the volumne of the couboid by finding the product of the area of the sheet and the height of this pile of sheets. This activity illustrates the idea that volume of a solid can ve deduce by thsi method also (if the base and top of the solid are congruent and parallel to each other and its edges are perpendicular to the base). Can you think of such objects whose volumne can be found by using this method?

You are given a potentiometer, a rheostat, one key, a driving cell for potentiometer, one galvanometer, two cells of unknown e.m.f., one two way key and some connecting wires. Using all those given drawa circuitdiagram for finding j the ratio ofthe e.m.fofthe two cells.
