L=1.01m Parameters L = ? g = 10ms^-2 pi = 22/7 T = 2sec From S.H.M T = 2pisqrt (L/g) Making L the subject of formula.. T = 2pisqrt (L/g) Divide both sides by color ...

3N_2H_4(g) + 4ClO_3^(-)(aq) rarr 6NO(g) + 6H_2O(l) + 4Cl^(-)(aq) This is one equation for the oxidation of hydrazine to nitrous oxide. It also accords with your question. Quite clearly, the equation …

Friction and other factors will always prevent this To be 100% efficient, all input energy would need to be converted in to useful output energy. In any real engine, there will always be friction (since there will …
