There are 11 points on a plane with 5 lying on one straight line and another 5 lying on a second straight line which is parallel to the first line. The remaining point not collinear with any two in the previous 10 points. The number of triangles that can be formed with vertices chosen from these 11 points

Figure shows the displacement tiime (x-t) graph of a body moving in a straight line which one of the graph shown in figure represents the velocity- time (v-t) graph of the motion of the body.

An object whose density is Pob falls from a certain height into a liquid whose density is pliq In the figure the potential energy W of the object is plotted along the vertical axis and the position of the object (its altitude) is plotted along the horizontal axis. The potential energy of the object at the level of the liquid is taken zero and the positive direction of the vertical axis (the W axis) is the one pointing upward from the liquid's surface. Determine which of the five straight lines, 1-5 , corresponds to an object with the highest density and which to an object with the lowest density. Is there a straight line among these five for which Pob = (112) Pliq ? The arrows on the straight lines point in the direction of motion of the object.

Fig. 2 (NCT). 6 shows x-t plot of one dismensional motion a particle. Is it correct to say from the graph that the particle moves in a straight line for t lt 0 and on a parabolic path form t gt 0 ? If not, suggest a suitable physical contxt for this graph.

Two particles start simultaneously from the same point and move along two straight lines. One with uniform velocity v and other with a uniform acceleration a. if alpha is the angle between the lines of motion of two particles then the least value of relative velocity will be at time given by
