Answer:
7.13mL
Explanation:
P₁V₁T₁ = P₂V₂T₂
P₁ = 3atm , V₁ = 2.1 mL , T₁ = 273 + 4 =277K
P₂ = 0.95atm , V₂ = ? , T₂ = 273 + 25 =298K
V₂ = P₁V₁T₂ / P₂T₁
V₂ = (3atm)(2.1 mL )(298K) / (0.95atm)(277K)
V₂ = 7.13mL
Answer:
The mass of air in the box is 0.78 grams.
Explanation:
A litre equals a cubic decimetre. By definition of density (), in grams per litre, we calculate the mass of air inside the cube (), in grams:
(1)
Where is the volume occupied by air within the cube, in litres.
If we know that and , then the mass of air is:
The mass of air in the box is 0.78 grams.
30 km/h * 17 h = 30*17 km/h *h
= 510 km
Wave speed = frequency (in Hz) x wavelength (in m) so wave speed = 11 x 0.011 = 0.121 m/s
Force, it is force because to be able to move anything you must use force.
