Duralumin. it mixed from copper and magnesium or aluminium. it use for flight
Answer: False
Explanation: False, what if its in space?
depth = side/lenght
the cube has all congruent sides
Volume = l³
Volume = 10³
Volume = 1000 cm³
Answer:
Protons
Explanation:
Electrons have a negative charge which are found in shells around the nucleus. The nucleus consists of protons and neutron and the neutron has a neutral charge.
Answer:
The molar average velocity is 0.0588 cm/s
The N₂ diffusion velocity relative to the mole average velocity is -0.1428 cm/s
The molar diffusional flux of N₂ is -3.9x10⁻³
Explanation:
Given data:
T = temperature = 265 K
O₂ = 25%
N₂ = 60%
CO₂ = 15%
vO₂ = -0.084 cm/s
vN₂ = 0.12 cm/s
vCO₂ = 0.052 cm/s
The molar average velocity is equal:

The N₂ diffusion velocity relative to the molar average velocity is:

The molar diffusional flux of N₂ is:
