Answer:
I think 0kg because they are flying.
The question is incomplete, complete question is:
A fluid occupying 
of volume has a mass of 4 Mg. Calculate its density and specific volume in SI, EE, and BG units.
Explanation:
1) Mass of liquid = m = 4 Mg = 4 × 1,000 kg = 4,000 kg
(1 Mg = 1000 kg)
Volume of the fluid = V =
Density of the fluid = D
Specific volume is the reciprocal of the density :
Specific volume of the fluid = 
2)
Density of the fluid in English Engineering units = D 
1 kg = 2.20462 lb
1 m = 3.280 ft
Specific volume of the fluid :
3)
Density of the fluid in British Gravitational System units = D 
1 kg = 0.06852 slug
1 m = 3.280 ft
Specific volume of the fluid :
I am not sure about this but I think it’s y
The answer for the following question is explained below.
The option for the following answer is "d".
Explanation:
The phlogiston theory of combustion:(Greek word phlogiston means <u><em>"BURN"</em></u>)
Phlogiston theory states that phlogisticated substances are the substances that contain phlogiston and dephlogisticate when burned.
Dephlogisticating is the process of releasing stored phlogiston,which is absorbed by the air.
Growing plants then absorb this phlogiston,which is why air does not spontaneously combust and also plant matte burns as well as it does.
The prevailing theory was that flammable materials contained a substance called phlogiston that was released during the combustion.
For example:
- phlogiston was transferring into the surrounding air.
