Show that slope of the plot of Ink against `1/T` is `-(Ea)/R`. Give the graphical representation of the plot.

Let R be the relation defined in the set A={1,2,3,4,5,6,7,8,9} by R={(a,b,):" both a and b are either odd or even"} . Show that R is an equivalence relation. Further show that all the lements of the subset {1,3,5,7,9} are related to one another and all the lement of the subset {2,4,6,8} are related to one another but no element of the subset {1,3,5,7,9} is related to any element of the subset {2,4,6,8} .

For a chemical reaction variation in concentraction, ln[R] vs. time (min) plot is shown below : If initial concentration of the reactant is half of the original concentration, how will t_(1//2) change?

From first order kinetics. We can write [R]=[R]_0e^(-kt) . Draw the graph the [R] against 't'. Why [R] can not be zero? How instantaneous rate is determined form the plot?

The Class X students of a secondary school in Krishinagar have been allotted a rectangular plot of land for their gardening activity.Sapling of Gulmohar are planted on the boundary at a distance of 1 m from each other.There is a triangular grassy lawn in the plot as shown in the Fig.7.14.The students are to sow seeds of flowering plants on the plot. (ii) What will be the coordinates of the vertices of trianglePQR if C is the origin?

A ball is dropped from a height of 90 m on a floor. At each collision with the floor, the ball loses one tenth of its speed. Plot the speed time graph of its motion between t = 0 to 12 s.

A drunkard walking in a narrow lane takes 5 steps forward and * 3 steps backward, followed again by 5 steps fonvard and 3 steps backward, and S0 on. Each step is 1 m long and requires 1 s. Plot the x-t graph of his motion. Determine graphically and otherwise how long the drunkard takes to fall in a pit 13 m away from the start.
