Pressure

What is the mass of a cube of edge length $10 \mathrm{cm}$ kept on a horizontal floor that exerts a pressure of $20 {\mathrm{kNm}}^{-2}$ due to its weight? [Take $g=10 {\mathrm{ms}}^{-2}$]

What is $\mathrm{MPa}$?

Pressure is equal to _____.

Atmospheric pressure is about $1.0\times {10}^5 \mathrm{Pa}$ on average. What is the downward force of the air on a desktop with the surface area $1.0 {\mathrm{m}}^2$ ?

Can we compare $\mathrm{Pa}$ and $\mathrm{N}$?

Is there any difference between Air Pressure and Water Pressure?

Force acting on a given area is called pressure.

A camel can run/walk in deserts very easily as compared to donkey, horse, dog, etc because of

It is easier to pierce a sharp object than a blunt object through a surface because

Pressure is a _____ (force/weight) acting on a certain area.

The SI unit of pressure is pascal (Pa).

Explain the terms -buoyancy, and pressure?

A block of weight $5 \mathrm{kgf}$ and dimensions $5 \mathrm{cm}\times 2 \mathrm{cm}\times 1 \mathrm{cm}$ rests on a table in three different positions with its base as $\left(i\right) 5 \mathrm{cm}\times 2 \mathrm{cm} \left(ii\right) 2 \mathrm{cm}\times 1 \mathrm{cm} \left(iii\right) 1 \mathrm{cm}\times 5 \mathrm{cm}$. Calculate the pressure exerted on the table in each case.

An elephant of mass $2000 \mathrm{kg}$ and foot area of $250 {\mathrm{cm}}^2$ standing on floor. Find the force exerted by the elephant on the ground. (Gravity$=10 \mathrm{m}/{\mathrm{s}}^2$).
