Question 5

A beaker contains a fluid of density

, specific heat

and viscosity

. The beaker is filled up to height h. To estimate the rate of heat transfer per unit area

by convection when beaker is put on a hot plate, a student proposes that it should depend on

,

and

when

(in °C) is the difference in the temperature between the bottom and top of the fluid. In that situation the correct option for

is:

Question 6

If n(U) = 300, n(A) = 60, n(B) = 120 and

= 30 then

is [U is universal set and A and B are subsets of U]

Question 7

If the total number of subsets of a finite set A is 56 more than the total number of subsets of a finite set B then the number of elements in A is?
