Assuming that the atmosphere has the same density anywhere as at sea level

\left(\rho=1.3 \mathrm{kgm}^{-3}\right)

and

g

to be constant

\left(g=10 \mathrm{~ms}^{-2}\right)

. What should be the approximate height of atmosphere?

\left(p_0=1.01 \times 10^5 \mathrm{Nm}^{-2}\right)

View answer and explanation

Correct option: B

8 \mathrm{~km}

Option B (8 km) is correct because the height of the atmosphere can be estimated by equating the atmospheric pressure to

\rho g h

, resulting in approximately 8 km.

With the increase in temperature viscosity of a liquid - Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: When you squeeze one end of a tube to get toothpaste out from the other end, Pascal's principle is observed.

Reason R: A change in the pressure applied to an enclosed incompressible fluid is transmitted undiminished to every portion of the fluid and to the walls of its container.

In the light of the above statements, choose the most appropriate answer from the options given below. Hydraulic lifts and hydraulic brakes are based
