study the following information carefully and answer the questions given below it. An exhibition is open for pubic since 9 am till 3 pm and again since 4 pm till 10 pm in a day. There are 12 batches of 1 hour each. The entry ticket bears a pass code made up of seven words, which changes every hour following a particular rule. The pass codes for 4 pm to 10 pm are same as those for respective hours during 9 am to 3 pm i.e., the pass code for 4 pm to 5 pm is same as that of 9 am to 10 am and so on. Following is an illustration of the code and steps of rearrangement for subsequent clock hours. First batch : 9 am to 10 am (4 pm to 5 pm) Pass code : dig more and you will find water Second batch : 10 am to 11 am (5 pm to 6 pm) Pass code : and dig find you water will more Third batch : 11 am to 12 noon (6 pm to 7 pm) Pass code : find and will you more water dig and so on. If the pass code for 5 pm to 6 pm is 'out in above over the field end', what will be the pass code for 1 pm to 2 pm ?

If the pass code for third batch is 'at study sleep and night child good', which batch will have the pass code 'child sleep night and study good at' ?

A gas bulb of 1 L capacity contains 2.0xx10^(11) molecules of nitrogen exerting a pressure of 7.57xx10^(3)Nm^(-2) . Calculate the root mean square (rms) speed and the temperature of the gas molecules. If the ratio of the most probable speed to the root mean square is 0.82 , calculate the most probable speed for these molecules at this temperature.

There of the fundamental constant of physics are the universal gravitational constant, G=6.7xx10^(-11) m^(3) kg^(-) s^(-2) , the speed of light c=3.0xx10^(8) m//s and Planck's constant, h=6.6xx10^(-34) Js^(-1) . two particles A and V are projected in the vertical plane with same initial velocity u_(0) fro part (0,0) and (l,-h) towards each other as shwon in figure The path of particle A with respect to particle B will be –
