Question

Statement-1 : Velocity gradient has the dimensions of frequency.
Statement -2 : Velocity gradient is rate of change of velocity with distance.
A. Statement -1 is true, Statement -2 is true , and Statement -2 is correct explanation of Statement -1.
B. Statement -1 is true , Statement -2 is true, but Statement -2 is not a correct explanation of Statement -1.
C. Statement-1 is true, but Statement -2 is false.
D. Statement-1 is false, but Statement -2 is true.

Answer 1

Correct Answer - (a)
Velocity gradient = change of velocity with distance `=(LT^(-1))/(L) = [T^(-1)] and T^(-1)` represents frequency. Therefore, both the statements are true and statement -2 is correct explanation of the statement-1.
