• What is heat rejection factor ???

• We know that in a vapour compression refrigeration system, the heat is rejected in a condenser.
The load on the condenser per unit of refrigeration capacity is known as heat rejection factor.
Heat rejection factor(HRF) = 1 + 1/C.O.P.

• The adjoint of a square matrix is the transpose of the matrix obtained by replacing each element of A matrix by its co-factor in |A|. Adjoint of A is briefly written as adj. A .

• What is the definition of transpose matrix & also explain properties ?

• Given a matrix A , then the matrix obtained from A by changing its rows into columns and columns into rows is called the transpose of matrix A. It is denoted by A’ or A^t.

• Properties of transpose of matrix A :-
If A’ & B’ denote the transpose of matrix A & B respectively , then
(1) (A’)’ = A i.e., the transpose of the transpose of a matrix is the matrix itself.
(2) (A + B)’ = A’ + B’ i.e., the transpose of the sum of two matrices is…[Read more]

• How many distance(meter) in one light year ..

• One light year = approximate (10)^16 meter.

• 9.46 x (10)^15

• (10)^16 m

• light complete distance in one second= 3x (10)^8
So, one light year = (3 x 10^8 ) x (365 x 24 x 60 x 60)
= 9.46 x (10)^15 meter
