Using a lever
Determine that the longer end of a lever travels farther and faster than the shorter end when the fulcrum is not in the centre. A baseball or cricket bat makes use of this benefit. List other examples of the use of levers and other simple machines to enhance speed.
State the law of radioactive decay. Show that radioactive decay is exponential in nature. Does the activity of a radioactive element depend on external physical conditions? La
A block is considered on a rough horizontal surface. If we give a variable force F on the block and if we enhance the force F continuously then we seem that block remains stationar
The force is in Newton The buoyant (upward) force exerted by water on a submerged object is given by the formula F= ?Vg, where ? is the density of water (1.0 x 10 3 kg/m 3 ),
Pascal's principle: Pressure applied onto an enclosed incompressible static fluid is transmitted undiminished to all of the parts of the fluid.
Dot Product A Easy demonstration of the relation among the dot product of 2 vectors and the angle among them. Move the slider to view the changes.

Draw a schematic diagram of a single optical fibre structure. Describe briefly how an optical fibre is fabricated. Explain in brief, the mechanism of propagation of light signal by
Evaluate the speed of the block A 2.00-kg block is attached to a spring force constant 500N/n. The block is pulled 5.00 cm to the right of the equilibrium and released from rest
A proton (mass = 1.67 x 10 -26 kg charge = 1.60 x 10 -19 C) is running at a speed of 8.50 x 10 4 m/s at a point in an evacuated region of space where the electric potential is 3
