Answer:

The correct answer is pulsar.

Explanation:

Protostar : Its a young star with contracting mass which gains mass from its parent molecular cloud. At this stage fusion process does not start.

Red dwarf: A star having lower surface temperature , luminosity, mass and size than of the sun.

White dwarf : its an ultimate stage for an average mass star like sun . its a small dense star with size relatively equal to planet.

Pulsar : A rotating neutron star that emits beam of radio waves and other electromagnetic radiations.

Black hole: It is region of space time with very strong gravitational pull that even smallest particle or electromagnetic wave is incapable to escape it.

A fuel tank holds 22.3 gallons of gasoline. If the density is 0.8206 g/mL, what is the mass in kilograms of gasoline in a full t

7nadin3 [17]

Answer:

$m=69.3kg$

Explanation:

Hello!

In this case, since the density is computed by dividing the mass of the substance by its occupied volume (d=m/V), we first need to realize that 0.8206 g/mL is the same to 0.8206 kg/L, which means we first need to compute the volume in L:

$V=22.3gal*\frac{3.78541L}{1gal}=84.415L$

Then, solving for the mass in d=m/V, we get m=d*V and therefore the mass of gasoline in that full tank turns out:

$m=0.8206g/L*84.415L\\\\m=69.3kg$

Best regards!
