Q1PhysicsUnit 7: Properties of Solids and Liquids

Assertion A liquid will flow faster and more smoothly from a sealed can when two holes are punched in the can than when one hole is punched. Reason The flow becomes streamlined with two holes rather than with one hole.

Q6PhysicsUnit 7: Properties of Solids and Liquids

A good lubricant should be highly

Q7PhysicsUnit 7: Properties of Solids and Liquids

Due to air a falling body faces a resistive force proportional to square of velocity

v,

consequently its effective downward acceleration is reduced and is given by

a=g-k v^{2}

where

k=

0.002 m^{-1} .

The terminal velocity of the falling body is

(\operatorname{in} \mathrm{m} / \mathrm{s})
