Answer» Distance travelled by the train = 480 kmLet the speed of the train be x kmphTime taken for the journey = 480/xGiven speed is decreased by 8 kmphHence the new speed of train = (x – 8) kmphTime taken for the journey = 480/(x – 8)480/x-8 =480/x=3480 (x-x+8)/x(x-8)=3480/3×8 =x^2-8x 1280 = x2– 8xx2– 8x – 1280 = 0On solving we get x = 40Thus the speed of train is 40 kmph The quadratic equation isx2-8x-1280=0 |

Answer» Between 81 and 237; 237 is greater than 81Division lemma of 237 and 81:Step 1:237 = 81 × 2 + 75Step 2:Since remainder 75 ≠ 0, division lemma is applied to 81 and 75 to get 81 = 75 × 1 + 6 Step 3:Since remainder 6 ≠ 0, division lemma is applied to 75 and 6 to get 75 = 6 × 12 + 3 Step 4:Since remainder 3 ≠ 0, division lemma is applied to 6 and 3 to get 6 = 3 × 2 + 0 The remainder is zero in step 4.Therefore, the divisor i.e. 3 in this step is the H.C.F. of the given numbers.The H.C.F. of 237 and 81 is 3Step 5:FromStep 3: 3 = 75 – 6 × 12 -----FromStep 2: 6 = 81 – 75 × 1Thus, fromStep 5, we, get 3 = 75 – (81 – 75 × 1) × 12⇒ 3 = 75 – (81× 12 – 75 × 12)Step 6⇒ 3 = 75 × 13 – 81× 12 FromStep 1, 75 = 237 – 81 × 2Thus, fromStep 6;3 = (237 – 81 × 2) × 13 – 81× 12⇒ 3 = (237 × 13 – 81 × 26) – 81× 12⇒ 3 = 237 × 13 – 81 × 38⇒H.C.F. of 237 and 81 = 237 × 13 + 81 × (–38)237 × 13 + 81 × (–38)is the representation of H.C.F. of 237 and 81 as linear combination of 237 and 81. |

Prove that the depth of the centre of pressure of a planearea immersed in a liquid is greater than the depth of itscentre of gravity |
|
Answer» Centre of pressure is the point at which the resultant force of buoyancy acts,while centre of gRavity is the point at which the resultant gravitational acts.(actually at these points the force doesn't acts alone ,but we choose a such point where the effective force can beassumed) Centre of pressure of a body immersed in a fluid depends on thephysical dimensions of The body,(ie. the shape and the volume displaced by the body). So it's dependent on the body you take,thatwhether the Centre of Pressure will lie ABOVE or BELOW the centre of graviTy. |

o. The sides AB and BC ofa square ABCD are produced to P and Qrespectively so that BP CQ. Prove that PD and AQ are equal andperpendicular to each other. |
|
Answer» ABCD is a square and AP = DQ we will consider ΔDAQ = ΔABP = 90° DQ = AP this is given AD = AB ( this is because the sides of the square are equal) We will use the RHS congruency rule here ΔDAQ ≅ ΔABP ∠1 = ∠3 ∠1 + ∠4 = 90° ∠3 + ∠4 = 90° In ΔAOD, By ASP, ∠3 + ∠4 + ∠AOΔ = 180° 90° = ∠AOΔ = 180° ∠AOΔ = 90° So AP and DQ are perpendicular. thanks Bhai kuch aur questions bhi ha uska bhi answer de do |
