Question

The time dependence of physical quantity p is given by p = Poe-
at?, where a is a constant and t is time. The constant a

Answer 1

Answer:

Given,

P=P

0

e

α

(−αt

2

)

As we know both P and P

0

are pressure so it have the same units, therefore αt

2

must be dimensionless for which

α=

T

=T

−2

So the dimension of α is [T
