Why is there a node at the closed end and an antinode at the open end?

State the difference between a node and an antinode.

A particle describes a distance x m in t sec, given by x = 4+5t+63t^3 . Find the velocity of the particle at the end of 2 secs and the acceleration at the end of 3 secs

A wire of length L and radius r is fixed at one end and a force F applied to the other end produces an extension l. the extension produced in another wire of same material of length 2L and radius 2r by a force 2F is

Where does a man hear a louder sound at the node or antinode?

What is the minimum distance between a node and an antinode produced in a stationary wave?

A uniform rope of length 12 m amd mass 6 kg hangs vertically from a rigid support.A block of mass 2 kg is attached to the free end of the rope.A transverse pulse of wave length 0.06m is produced at the lower end of the rope.What is the wavelength of the pulse when it reaches the top of the rope?

A bucket made up of metal sheet is in the form of a frustum of height 16 cm (closed at the lower end but open at the upper end) with radii of the lower and upper ends are 8 cm and 20 cm respectively. Find the cost of the bucket if the cost of the metal sheet used is ₹ 15.00 per 100 cm (pi = 3.14) .

A beam of metal supported at the two ends is loaded at the centre. The depression at the centre is proportional to

A ladder is at rest with its upper end against a wall and the lower end on the ground. Is the ladder more likely to slip, when a man stands on it at the bottom or a the top? Give reason.

Two children are at opposite ends of an aluminium rod. One strikes the end of the rod with a stone. Find the ratio of times taken by the sound wave in air and in aluminium to reach the second child.
