Question

A pressure of 25 kPa is acting on an area of 25 m2.
a. Find the thrust acting on the said area
b. If the thrust acting is due to a cubical block of side 5 m, find the density of the material of the block.
c. Given that the acceleration due to gravity on Mars is 40% of that of the Earth, find the pressure the block would exert on the same area on Mars

1. What will be the height of mercury column in a barometer, if it is taken to the moon?2. Two million molecules per square inch hit against a window pane every second. This force is sufficient to power a steam engine or a turbojet. Such enormous force should shatter the glass into pieces. But this does not happen. Why?

3. A pressure of 25 kPa is acting on an area of 25 m2.

Find the thrust acting on the said area

b. If the thrust acting is due to a cubical block of side 5 m, find the density of the material of the block.

c. Given that the acceleration due to gravity on Mars is 40% of that of the Earth, find the pressure the block would exert on the same area on Mars.
