each question constain STATEMENT-1(Assertion ) and STATEMENT - 2 (reason). examine the statement carefully and work the correct answer accoridng to the instructions given below : TRUESTAMENT-1: More heat evolved in physiorpiton than in chemisorption. STATEMENT-2: Molecules of adsorbate and adsorbent are held by van der Waal's forces in physisorption and by chemical bonds in chemisorption.
A
if both the statement are TRUE and STATEMENT -2 is the correct explanation of STATEMENT - 1
B
If both the statement are STATEMENT -2 is NOT the correct explanation of STATEMENT -1
This section contains 2 questions. Each question contains STATEMENT-I (Assertion) and STATEMENT-2 (Reason). Each question has 4 choices (A), (B), (C) and (D) out of which ONLY ONE is correct. Statement-1: The equation sin^(2) x + cos^(2) y=2 sec^(2) z is only solvable if sin x =1, cos y=1 and sec z=1 where x, y, z in R because Statement - 2 : Maximum value of sinx and cosy is 1 and minimum value of secz is 1.
This section contains 2 questions. Each question contains STATEMENT-I (Assertion) and STATEMENT-2 (Reason). Each question has 4 choices (A), (B), (C) and (D) out of which ONLY ONE is correct. Statement - 1 : The minimum value of the expression sin alpha + sin beta + sin gamma where alpha, beta , gamma are real numbers such that alpha + beta + gamma=pi , is negative because Statement - 2 : alpha, beta, gamma are angles of a triangle
This section contains 2 questions. Each question contains STATEMENT-I (Assertion) and STATEMENT-2 (Reason). Each question has 4 choices (A), (B), (C) and (D) out of which ONLY ONE is correct. Statement - 1 : The maximum and minimum values f(x) = (1)/( 3 sin x + 4 cos x-2) does not exist Statement - 2 : The given faction is an unbounded function.
The following questions consist of two statements, one labelled as 'Statement I' and the other 'Statement II'. You have to examine these two statements carefully and decide if the Statement I and the Statement II, are individually true and if so, whether the Statement II is the correct explanation for the given Statement I. Select your answer to these items using the codes given below and then select the correct option. Statement-1 : The value of tan^(-1)2+tan^(-1)3=(3pi)/4 Statement-2 : If x gt 0, y gt 0, xy gt 1" then "tan^(-1)x+tan^(-1)y=pi+tan^(-1)((x+y)/(1-xy))
