Question

a glass block of density 2.5gcm-3 would exert on a horizontal surface, if the block measures 20cm x 10cm x 5cm. Determine

Maximum pressure it exerts on the surface.(3mks)





Minimum pressure it exerts on the surface.(3mks)

Answer 1

Answer:

glass block of density 2.5gcm-3 would exert on a horizontal surface, if the block measures 20cm x 10cm x 5cm. Determine

Maximum pressure it exerts on the surface

the pressure 500 m below the surface of the ocean if pressure on the free surface of liquid is one atm.

( = of sea water = 1060 kg/m3

)

Answer 2

Answer:

500N/m²

Explanation:

since we have the volume and density we can find the mass by doing 20×10×5cm=1000cm³ whichis now the volume

and then you multiple the volume and the density 1000cm³×2.5=2500 which will be the mass

to get the force multiply the mass by 10 =2500×10=25000 and divide it by 10×5=50 =25000÷50=500N/m²
