We know strong acid ionizes completely whereas weak acid is partially ionizes. This is one major difference between strong and weak acid. Since strong acid ionizes completely, it produces more hydrogen ions than a weak .....

When the student dips the blue litmus into lemon juice it will turn red because lemon contains citric acid. So, lemon  is acidic in nature. Hence, it turns the blue litmus .....

Acid are those substance that produce H+ ions when dissolved in water. HCl ionizes as H+ and Cl​​​​​- when dissolved in water. Similarly it has sour taste and changes Blue litmus to red.  So it is called .....

Following are the roles that I want to play against different social problems in future: - I will set up a local club to raise awareness among the people - I will mobilize the young generation in the work of spreading message to the .....

The major reasons behind child trafficking are as follows: - prevailing illiteracy among the common population - lack of awareness among the people regarding such social problem - the innocent nature of children help them tempt easily - valuable .....

3+23-2=a+b2 or, 3+23-2=a+b2 Rationalizing we get, or,  3+23-2×3+23+2=a+b2 or, 3+2232-22=a+b2           ( ( a + b ) ( a - b ) = a² - b² )  or, 9+62+29-2=a+b2  .....

23+3223-32 We know ( a + b ) (a - b ) = a² - b² =232-322 = 4×3-9×2 = 12 - 18 = .....

Given terms are :  66 , 73 ,84  The power of roots are different so lets make it same by taking LCM which is 12 in our case. We also have: a√(y) = a⨉b√(y ⨉ yb) for  .....

We have: A + B + C = π  or, A = π - ( B + C )  Taking sin on both sides:  sin A = sin ( π - ( B + C ) ) or, sin A = sin ( B + C )  Similarly , sin B = sin (A + C ) sin C = sin (A + B) Now,  LHS .....

The reason for the misunderstanding between Rajendra Laxmi and Bahadur Shah was their violent and angry disagreement. This resulted in regular conspiracies and .....

We can derive: A + B + C = π Adding A in both sides: 2A + B + C = A + π or, 2A = π + A - ( B + C )  taking tangent on both sides: tan 2A = tan ( π + (A - ( B + C )) ) Taking minus common or, tan2A = tan .....

Here, join A&R  and Q&U. Then , AR is perpendicular to MR  and QU is perpendicular to KU. Now, Area of //gm RMAS = AR ⨯ MR = b ⨯ p   [ RS = h and PR=MR= AS= p,so AR = b.] Similarly area of //gm .....

Here, join Q & S as in figure. Now,  1. ∡QST = 1/2 of ∡QOT           [ Inscribed angle is half of  central angle on same arc QT.]] 2. ∡SQR = 1/2 of ∡SOR        .....

Here, LHS = cosA/2 . sinB/2 . sinC/2 + cosB/2 . sinC/2 . sinA/2 + cosC/2 . SinA/2 . sinB/2          = SinC/2 [ cosA/2.sinB/2 + sinA/2.cosB/2] + cosC/2 . SinA/2 . sinB/2          .....
