A 0.140 m high cylinder

is filled with mercury

(density = 13600 kg/m^3).

What is the pressure at the

bottom of the cylinder?

The value of pressure inside the cylinder is 18.68 K Pa.

Explanation:

Given data

Height h = 0.14 m

Density = 13600

We know that

Pressure inside the cylinder is given by the formula

P = g h ------- (1)

here

= density of fluid = 13600

g = acceleration due to gravity = 9.81

h = height of the cylinder = 0.14 m

Put all the values in above equation

P = 13600 × 9.81 × 0.14

P = 18678.24 Pa

P = 18.68 K Pa

Therefore the value of pressure inside the cylinder is 18.68 K Pa

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
