Question

The time dependence of Physical quantity p is given by p=poe-at^2, where a is constant & t is time. the constant a
a. is dimension less
b. has dimension T ^-2
c . has dimension T^2
d. has dimension of p ​

Answer 1

Answer:

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

2

1

=T

−2

So the dimension of α is [T

−2

]
