dimension = 30.0 m ✕ 15.0 m ✕ 5.0 m.
density = 1.20 kg/m3
(a)volume = lenght * breadth * height
= 30 * 15 * 5
= 2250 metre cube = 2.25 cubic meter
(b) mass of air = density * volume
mass of air = 1.2 * 2250
mass of air = 2700kg
weight = mass * 9.8
= 2700 * 9.8
= 26,460 N
- The definition of Density is the amount of matter in a given space, or volume
- Density = mass/volume
- units for density kg/m^3
- Density of water 1g/ml
- Salt water is denser that is why don't sink as easily.

Answer:heat brings it up then down
Explanation:
Energy is in Joules ( J )
specific heat capacity is in ( Joules per Kilogram per degree Celsius) ( J/kg C )
Answer:
it has constant angular velocity
Explanation:
an object moving in a uniform circular motion moves with constant angular velocity about a point
The correct answer is A. While the Big Bang is very possible it is still a theory. Even if you accept it, you have to see its flaws. Nothing is without flaw. There are many things it doesn't account for. Now, again this is not to say it is untrue just flawed. The best argument against it or anything similar would be that no one seen it happen.
