The complete solution of the current in the sinusoidal response of R-L-C circuit is? Correct Answer i = c1 e(K1+K2)t + c1 e(K1-K2)t + V/√(R2+(1/ωC-ωL)2) cos⁡(ωt+θ+tan-1)⁡((1/ωC-ωL)/R))

The complete solution for the current becomes i = c1 e(K1+K2)t + c1 e(K1-K2)t + V/√(R2+(1/ωC-ωL)2) cos⁡(ωt+θ+tan-1)⁡((1/ωC-ωL)/R)).

A chemical solution appears green when the salt concentration is 8 grams per litre (gpl) and red when it is 10 gpl. Pure water was added to the solution of 1 litre of 15 gpl solution till it turned green. Then 125 ml of the green solution is taken out and x grams of salt is added to the green solution to make it red. Another 500 ml of the final solution was taken out and y litres of green solution is added to get a resultant solution of concentration 9.6 gpl.  Assume adding salt doesn’t change its volume and find the ratio of x and y. 
Below are given two sets, Set - I which gives modalities of operant conditioning and Set - II which provides the types of reinforcement, the types of responses (responses made or withheld) and the presence or absence of cue. Match the two sets and indicate your answer by choosing from the code : Set - I (Modalities of operant conditioning procedures) Set – II           (Conditions and contexts) (a) Reward training (i) Positive reinforcement, response made, with cue present (b) Escape training (ii) Positive reinforcement, response withheld with cue absent (c) Discriminated omission training   (iii) Positive reinforcement, response made with cue absent (d) Active avoidance   (iv) Negative reinforcement, response made with training (e) Punishment training (v) Positive reinforcement, response withheld with cue present   (vi) Negative reinforcement, response withheld with cue absent

Consider the following statements regarding reciprocity theorem : 1. In any passive linear bilateral network, if the single voltage source Vx, in branch x produces the current response Iy, in branch y, then the removal of the voltage source from branch x and its insertion in branch y will produce the current response iy in branch x. 2.
