It is measured that 3/4 of a body's volume is submerged in oil of density 800kg/m³
Evgesh-ka [11]

Complete question:

It is measured that 3/4 of a body's volume is submerged in oil of density 800kg/m³. What is the specific gravity of oil?

Answer:

The specific gravity of the oil is 0.8.

Explanation:

Given;

density of the oil, \rho_o = 800 kg/m³

density of water, \rho_w = 1000 kg/m³

The specific gravity of any substance is the ratio of the substance density to the density of water.

Specific gravity of the oil = density of the oil / density of water

Specific gravity of the oil = 800/1000

Specific gravity of the oil = 0.8

Therefore, the specific gravity of the oil is 0.8.

One of Lex Luthor's henchman attacks Superman, shooting a rapid-fire stream of 3.3 g bullets at him at a rate of 112/min. The sp
igor_vitrenko [27]

Answer:

3.2451N

Explanation:

Mass of the bullet (m) = 3.3g = 3.3*10^{-3}Kg

Speed of the bullet (V)= 527m/s

Rate of bullet (r) = 112/min = 1.866\sec

We can calculate with this information the average acceleration of bullets

a=V*r = 527\frac{m}{s}\frac{1.866}{s} = 983.38m/s^2

The force is given by,

F=ma\\F=(3.3*10^{-3})*983.38m/s^2 = 3.2451N

That is just because he is Superman.

What is the difference between the specific heat of a substance and the total amount of heat of that substance ?
Dominik [7]

Explanation:

Specific heat of a substance is defined as the amount of heat that is required to raise the temperature of one mole or mass of a substance by 1°C.

The total amount of heat of a substance is the amount of heat required to raise the temperature of the given mass of the substance by 1°C.

Specific heat is an intensive property and does not depend on the amount of matter that is present within a substance.

Total amount of heat is an extensive property of matter and it is predicated on the amount of matter present.
