Figure. 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.

Consider the following statements (1) Gases are the most compressible state of matter. 2. Gases take the shape of the container. 3. The density of gases is higher than that of liquids Which of the following statmenet(s) given above is/are corrent?

Which of the following sets are empty sets? Justify your answer. (i) A={x : x^(2)=4 and 3x=9} (ii) The set of all triangles in a plane having the sum of their three angles less than 180.

Let theta=(a_(1),a_(2),a_(3),...,a_(n)) be a given arrangement of n distinct objects a_(1),a_(2),a_(3),…,a_(n) . A derangement of theta is an arrangment of these n objects in which none of the objects occupies its original position. Let D_(n) be the number of derangements of the permutations theta . There are 5 different colour balls and 5 boxes of colours same as those of the balls. The number of ways in which one can place the balls into the boxes, one each in a box, so that no ball goes to a box of its own colour is

Given below is the sketch of a plant for carrying out a process. (i) Name the process occuring in the above plant. (ii) To which containeer does the net flow of solvent take place ? (iii) Name one SPM which can be used in this plant. (iv) Give one practical use of the plant.

Take three different colour sheets , place one over the other and draw a triangle on the top sheet. Cut the sheets to get triangles of different colour which are identical. Mark the vertices and the angles as shown. Place the interior angles angle1,angle2 and angle3 on a straight line, adjacent to each other, without leaving any gap. What can you say about the total measure of the three angles angle1,angle2 and angle3 ? Can you use the same figure to explain the ''Exterior angle property'' of a triangle ? If a side of a triangle is stretched, the exterior angle so formed is equal to the sum of the two remote interior angles.
