The formulas for the three speeds mentioned here can be derived by mathematical techniques. The most probable speed is the square root of (2 R T / M), where R = gas constant, T = temperature, M = molecular mass. For the gas N 2, which temperature gives the highest most probable speed: 500 C, 600 K, or 700 F?
Idris Elba. An only child, Idris Elba was born and raised in Hackney, London, England. His father, Winston, is from Sierra Leone and worked at a Ford motor factory. His mother, Eve, is from Ghana and had a clerical duty. Idris attended school in Canning Town, where he first became involved in acting.
He made his name as a hard-nosed detective in Luther and a notorious drug runner in The Wire. But it seems Idris Elba isnât so confident when it comes to flying - especially when asked to perform a number of 360-degree loops and rolls in a light aircraft 4,000ft in the air.
