Question

if the value of atmospheric pressure is 10 to the power 6 dyne/cm,find it's value in SI units

Answer 1

1N=10^5dyne
10^-5N=1dyne
10N=10^6dyne
1cm=10^-2m
1cm^2=10^-4m^2
10^6dyne/cm^2=10N/10^-4m^2
=10^5N/m^2
Si unit of pressure=Pa=N/m^2
So, answer is 10^5Pa

Answer 2

Answer:

Converting atm. Pressure from 10^6 dyne/cm to SI unit.

Explanation:

Now the SI unit of atm. Pressure is Newton/meter.

So we need to keep in mind that

1 dyne / cm = 0.001 N/m

So like wise, 10 dyne / cm = 0.01 N/m

10^1 = 10 and 10^2 = 10, like wise 10^6 = 1000000

Now 1000000 dyne / m = 1000 N/m.
