Two line segments and intersect at E such that If AE = 4cm, BE = 3cm, CE=6cm and DE = x cm then x = ?

In the figure, AB = BC = CD = DE = EF and AF = AE Then = ?

In the figure, AB = AC, and Then

Hence BC=CD

In the figure, ‘x° ’ and ‘y° ’ are two exterior angle measures of DABC Then x° + y° =

Hence x+y>180^o

In then

The vectors are mutually perpendicular then

If be the three vectors such that then

If then

If represents the reciprocal system of vectors of then

The given graph shows the variation of velocity with displacement. Which one of the graph given below correctly represents the variation of acceleration with displacement

The variation of velocity of a particle moving along a straight line is shown in the figure. The distance travelled by the particle in 4s is

A ball is thrown vertically upward. Ignoring the air resistance, which one of the following plot represents the velocity-time plot for the period ball remains in air?

The velocity of a particle moving in a straight line varies with time in such a manner that graph is velocity is and the total time of motion is

i) Average velocity of the particle is
ii) such motion cannot be realized in practical terms

Figure given shows the distance –time graph of the motion of a car. It follows from the graph that the car is

The displacement-time graphs of two moving particles make angles of and with the -axis. The ratio of the two velocities is

An elevator is going up. The variation in the velocity of the elevator is as given in the graph. What is the height to which the elevator takes the passengers?
