The sum of all the molar fraction is equal to. . . . . .
1>10
2) 100
3)1000
4)1

[kashibhayya]

When no heat enters or leave the system then the entropy is. . . . . .

A wire carries a steady current of 2A. The charge that passes a cross section in 2 second is:
A). 3.2*10^ -19C
B). 6.4*10^ -19C
C). 1C
D). 2C
E). 4C

[kashibhayya]

The charge on an electron is 1.6*10^ -19C. In a circuit, the current flowing is 1A. How many electrons will be flowing through the circuit in a second?
A). 1.6*10^19
B). 1.6*10^ -19
C). 0.625*10^19

Which kingd0m is kn0wn as kingd0m prokaryates.
1)kingd0m protesta
2) kind0m plantae
3)kingd0m fungi
4)kingd0m m0nera.

[kashibhayya]

Value of permittivity of the free space is:
1). 8.85*10^ -12 Nm2C-2
2). 9.0*10^11 Nm2C-2
3). 8*10^8 Nm2C-2
4). 8.85*10^-12 C2N-1m-2

[kashibhayya]

Dimension of coulumb:
A=C/sec
=> C=A*Sec
=> [C]= [AT]
Dimension of permittivity of free space:
F= 1/4fi€0 q1q2/r^2
=> €0= q^2/Fr^2 because 4fi is a pure number and has no dimension and unit.
€0= C^2/Nm^2
[€0]= [AT]^2/[MLT^ -2][L^2]
[€0]=[A^2T^2]/[ML^3T^ -2]
[€0]=[M^ -1L^ -3T^4A^2].

[kashibhayya]

1 dyne is equal to what?
1). 10^ -5 N
2). 10^ 5 N
3). 10^6 N
4).10^ -6 N
