Show experimentally that pressure increases with the depth.

How did Robert Boyle show experimentally that a coin and a piece of paper when dropped simultaneously from same height in vacuum fall with same acceleration ?

Describe an experiment to show that pressure is the same at all points at the same depth.

Show by an experiment that Speed of wave pulse increases as tension increases.

Explain experimentally that stem helps in conducting water upwards.

A square-based tank of capacity 250 cu m has to bedug out. The cost of land is Rs 50 per sq m. The cost of digging increases with the depth and for the whole tank the cost is Rs 400 xx (depth)^2 . Find the dimensions of the tank for the least total cost.

Assertion: Lambda_m for weak electrolyte shows a sharp increases when the electrolytic solution is diluted. Reason: For weak elelctrolytes degree of dissociatin increases with dilution of solution.
