A body emits maximum energy at 4253 Å and the same body at some other temperature emits maximum energy at 2342 Å . Find the ratio of the maximum energy radiated by the body in a short wavelength range.

A siphon is used to drain water (density =rho ) from a wide tank. The inlet and outlet mouth of the siphon are at the same horizontal level and the highest point of the siphon tube is at a height H from the mouth of the tube. Height of water in the tank above the tube mouth is h (see fig). Atmospheric pressure is P_(0) . (a) Will the water drain out in this siphon? if yes, at what speed (V)? (b) Find pressure at the top of the siphon tube (call in P) (c) Find pressure just inside the left mouth of the tube. (d) If left part of the tube is slightly cut short, without disturbing anything else, what effect it will have on V and P? (e) If the right end of the tube is lowered by adding more lenght of tube, it was observed that flow stops when lenght of right limb of the tube becomes H_(0) . Find H_(0) .

In the following items, each passage consists of six sentences. The first sentence (S_(1)) and the final sentence (S_(6)) are given in the beginning. The middle four sentences in each have been removed and jumbled up. These are labelled P, Q, R and S.

In the circuit shown all live resistors have the same volue 200 oms and each cell has an emf 3 volts. Find the open circuit voltage and the short circuit current for the terminals A and B.

In the circuit given as Fig. 14.7, Boojho observed that copper is deposited on the electrode connected to the negative terminal of the battery. Paheli tried to repeat the same experiment. But she could find only one copper plate. Therefore she took a carbon rod as negative electrode. Will copper be still deposited on the carbon rod? Explain your answer.
