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.
It all depends on what is happening in a vast factory complex on the edge of town, because Alba is home to Ferrero, the maker of Nutella, Kinder Surprise eggs and, of course, Ferrero Rocher. The family-owned company that began with a small patisserie on a unremarkable backstreet has grown into an â¬8.4bn (Â£6bn) empire which spans 53 countries.
