Question

Pls solve this fast pleeassee​

Answer 1

Explanation:

Weight of the body = 250N

Area of contact = 10m^2

Pressure = Force x Area

= 250x10

= 2500Nm2

Answer 2

Answer:

Explanation:

a) Given-

Force - 250N

Area = 10m^2

Pressure = F/A

P = 250/10

P = 25Pa

b) 2 Applications of Atmospheric Pressure -

Straw : When a man sucks up the fluid from straw the pressure inside is moderately low and accordingly atmospheric pressure outside powers up the fluid into straw.

Vacuum cleaner : When a vacuum cleaner is turned on, the pressure inside tumbles off because of air inside And Starts Cleaning The Things
