6 0

Answer:

A.100J

Explanation:

Given parameters:

Force on car = 20N

Distance = 5m

Unknown:

Work done = ?

Solution:

Work done is the product of force and distance;

Work done = force x distance;

Insert given parameters and solve;

Work done = 20 x 5 = 100J

Given that a pipe having a diameter of 1.5 feet and a height of 10 feet, what is the psi at 5 feet ?

grin007 [14]

Answer:

The pressure is 2.167 psi.

Explanation:

Given that,

Diameter = 1.5 feet

Height = 10 feet

We need to calculate the psi at 5 feet

Using formula of pressure at a depth in a fluid

Suppose the fluid is water.

Then, the pressure is

$P=\rho g h$

Where, P = pressure

$\rho$ = density

h = height

Put the value into the formula

$P=1000\times9.8\times1.524$

$P=14935.2\ N/m^2$

Pressure in psi is

$P=2.166167621\ psi$

$P=2.167\ psi$

Hence, The pressure is 2.167 psi.
