The volume of a piece of metal of a mass 6 gram is 15cm3. What is the density of the metal piece?

torisob [31]

Answer:

0.4 g/cm^3

Explanation:

The density of an object can be found using the following formula.

d= m/v

where m is the mass and v is the volume.

The mass of the metal is 6 grams and the volume is 15 centimeters^3

m=6 g

v= 15 cm^3

Substitute these into the formula.

d= 6 g/ 15 cm^3

Divide 6 g by 15 cm^3 (6/15=0.4)

d= 0.4 g/ cm^3

The density of the metal is 0.4 grams per cubic centimeter.

An air compressor and takes atmospheric Air at 14.7 PSI and increases its pressure to 150 psi ( Gauge). the pressurized air is s

Yuliya22 [10]

Answer:

The absolute pressure of air inside the tank is 164.7 psi.

Explanation:

Given that,

Atmospheric pressure = 14.7 Psi

Gauge pressure = 150 psi

We need to calculate the absolute pressure of air inside the tank

Using formula of absolute pressure

$P_{ab}=P_{g}+P_{atm}$

Where, $P_{g}$ = gauge pressure

$P_{atm}$ =atmospheric pressure

Put the value into the formula

$P_{ab}=150+14.7$

$P_{ab}=164.7\ psi$

Hence, The absolute pressure of air inside the tank is 164.7 psi.
