The second law states that if the physical process is irreversible, the combined entropy of the system and the environment must increase. The final entropy must be greater than the initial entropy for an irreversible process: Sf > Si (irreversible process)

The unit of electric field intensity is newton per coulomb i.e. N/C.
Newton is the unit of force and has dimensions [MLT−2]
Coulomb is the unit of charge and has the dimensions [A1T1]
Hence the dimension of field will be [MLT−3A−1]

The parallax method is a method of measuring the two angles and sides of a triangle formed by a star six months later, the Earth on one side, and the Earth on the other. Astronomers use parallax to find the distance between adjacent stars in the universe.

Given that,
x = a + bt + ct2 + dt3
x is the displacement. Now, by principle of homogeneity
a = bt = ct2 = dt3 = x
Now a = L
[bt] = L
b = [LT-1]
c = [LT-2]
d = [LT-3]
Hence, the dimension of a, b, c and d is L, [LT-1], [LT-2] and [LT-3]
