In a conductor, 6.25 xx 10^(16) electrons flow from its end A to B in 2 s. Find the current flowing through the conductor. (e = 1.6 xx 10^(-19) C)

In the following circuit , E_1 = 4V, R_1 = 2 Omega, E_2 = 6 V, R_2 = 2Omega, and R_3 = 4Omega. Find the currents i_1 and i_2

In parallel L-C circuit current from the source is 1 A and current from the inductor is 0.6 A . The current from capacitor is

Every gram of wheat provides 0.1 gm of proteins and 0.25 gm of carbohydrates. The corresponding values f rice are 0.05 gm and 0.5 gm respectively. Wheat costs Rs. 4 per kg ad rice Rs. 6. The minimum daily requirements of proteins and carbohydrates for an average child are 50 gms and 200 gms respectively. In what quantities should wheat and rice be mixed in the daily diet to provide minimum daily requirements. In what quantities should wheat and rice be mixed in the daily diet to provide minimum daily requirements of proteins and carbohydrates at minimum cost?
