Description : How do I justify with steps 8(2q)?
Last Answer : 8(2q) = (8*2)q = 16*q = 16q.
Description : Simplify `((q^(3-7q)xxq^(6-2q))/(q^(2q)xxq^(9-2q)))^(1/9)`.
Last Answer : Simplify `((q^(3-7q)xxq^(6-2q))/(q^(2q)xxq^(9-2q)))^(1/9)`.
Description : In the formula, `x=(p+5q)/(sqrt(3)+2q)`, make q the subject.
Last Answer : In the formula, `x=(p+5q)/(sqrt(3)+2q)`, make q the subject.
Description : Find `(x+2p)/(x-2p) +(x+2q)/(x-2q),"when x" = (4pq)/(p+q)`.
Last Answer : Find `(x+2p)/(x-2p) +(x+2q)/(x-2q),"when x" = (4pq)/(p+q)`.
Description : If vectors P = 2i + 3j - k and Q = 2i - 5j + 2k. Find i. P + Q ii. 3P - 2Q
Last Answer : If vectors \(\overset\rightarrow{P}\) = 2i + 3j - k and \(\overset\rightarrow{Q}\) = 2i - ... \overset\rightarrow{P}\) - 2\(\overset\rightarrow{Q}\)
Description : In otto cycle compression ratio is 8. Calculate air standard efficiency. Will it be grater than Carnot Cycle ? Justify your answer.
Last Answer : No, the Otto cycle efficiency 56.47% will always be lower than Carnot cycle efficiency. Justification: Carnot theorem states that keeping operating conditions same, Carnot engine is more efficient than any other engine. So, Otto cycle efficiency is lower than Carnot cycle efficiency.
