Figure 3.21 shows the x-t plot of one-dimensional 4 motion of a particle. Is it correct to say from the graph that the particle moves in a straight line for t 0 ? If not, suggest a suitable physical context for this graph.

Figure 3.24 gives the x-t plot of a particle in one-dimensional motion. Three different equal intervals of time are shown. In which interval is the average speed greatest, and in which is it the least ? Give the sign of average velocity for each interval.

The figure VSAQ 29 shows a plot of three curves a,b,c, showing the variation of photocurrent in collector plate potential for three different intensities I_1 , I_2 and I_3 having frequencies v_1 , v_2 and v_3 respectively incident on a photosensitive surface. Point out the two curves for which the incident raidations have the same frequency but different intensities.

Refer to the plot of temperature versus time (shown in the figure) showing the changes in the state of ice on heating (not to scale). Which of the following is correct?

The figures SAQ 13(a) shows a bar magnet M falling under gravity through an air cored coil. Plot a graph showing variation of induced e.m.f. with time(t). What does the area encloed by E-t curve depict?

The graph of compressibility factor (Z) vs. P for one mole of a real gas is shown in following diagram. The graph is plotted at constant temperature 273K. If the slope of graph at very high pressure ((dZ)/(dP)) is ((1)/(2.8))atm^(-1) , then calculate volume of one mole of real gas molecules (in L/mol) Given : N_(A)=6xx10^(23) and R=(22.4)/(273)L atmK^(-1)mol^(-1)

Mercury has an angle of contact equal to 140^@ with soda lime glass. A narrow tube of radius 1.00 mm made of this glass is dipped in a trough containing mercury. By what amount does the mercury dip down in the tube relative to the liquid surface outside ? Surface tension of mercury at the temperature of the experiment is 0.465 N m^-1 . Density of mercury = 13.6xx 10^3 kg m^-3 .

For the wave described in the above question, plot the displacement (y) versus time (t) graphs for x=0.2 and 4 cm. What are the shapes of these graph? In which aspects does the oscillatory motion in a travelling wave differ from one point to another: amplitude,frequency or phase?
