Question

A)Suggest two ways to decrease pressure on a surface B)Density of an object is 1.8g/cm cube. Express it in kg/m cube?

Answer 1

B
1 g/cm³ = 1000 kg/m²
∴1.8 g/cm³ = 1800 kg/m³
A 
1 by ncreasing the surface area on which force is acting 
2 and by decreasing the magnitude force

Answer 2

pressure can be decreased in the following ways :-

1)by increasing the surface area on which tge force is acting as pressure is inversely proportional to area .

2)by decreasing the force applied to an area as pressure is directly proportional to force applied.

==============================

1g/cm^3 = 1000kg/m^3

density = 1.8 g/cm^3
= 1.8 x 1000 kg /m^3
=1800 kg/m^3
