In a hydraulic press used for compressing wool, the area of the pistion is 0.1 `m^2` and the force exerted along the piston rod is 200 N. find the pressure and If the area of larger cylinder 0.8 m and the total crushing force exerted on a bale of wool.

Curved surface area of a right circular cylinder is 4.4 m^2 . If the radius of the base of the cylinder is 0.7 m, find its height.

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 tent will not be covered with canvas.)

A doctor applies a force of 50 n to the piston of syringe of area 1.5 m^2 . The increase in pressure of the fluid in the syringe is

A force of 200 N acts on an area of 1cm^2 uniformly . Find the pressure in Pascal.

A car of mass m starts from rest and acquires a velocity along east vec v = vhati (v>0) in two seconds. Assuming the car moves with uniform acceleration, the force exerted on the car is

Two bodies of masses m_1 and m_2 are connected byh a ight string passing over a smooth light pulley fixed at the end of an inclined plane.the mass m_1 lies on the inclined plne nd m_2 bags vertically.The system is at rest.Find the angle of the inclination of the inclined plane and the force exerted by the inclined plane on the body of mass m_1 .
