The velocity-time graph of a certain body is shown in the following graph. The path of the graph that shows deceleration of the body is

The displacement-time graph of a body is shown in the figure. The part of the graph that represent the body at rest is

The magnitude of acceleration due to gravity upon.

When a body fall freely under the gravity. The final velocity of body will be

The relation ''less than'' in the set of natural number is

Hence, the relation is only transitive.

The relation R defined in A = {1, 2, 3} by a Which of the following is false-

Hence, Range of R = {5} is the wrong option.

Let R be a relation defined in the set of real numbers by a R b 1 + ab > 0. Then R is-

Therefore, the given relation R is symmetric.

A and B are two sets having 3 and 4 elements respectively and having 2 elements in common. The number of relation which can be defined from A to B is

Therefore, the number of relations which can be defined from A to B are ..

Let L denote the set of all straight lines in a plane. Let a relation R be defined by Then R is-

Hence, the relation R is symmetric.

Let X={1,2,3,4} and Y={1,3,5,7,9} . Which of the following is relations from X to Y-

So the correct relations are R2 and R3.

If Q=then-

Hence,  is correct.

Let Aand =R-D, then the set D is

Therefore, set of D is .

Which set is the subset of all given sets ?

Therefore, { } is a subset of all givens sets.

Let A and B be two sets such that n(A) = 70, n(B) = 60 and = 110. Then is equal to-

Therefore, n(A∩B) = 20

The shaded region in the given figure is

Which of the following are true ?

Therefore, from the given options,  is true.
