Question

If OH = 9a units and OE = 3b units, where ABCD is a square, then area of ABCD = area of 4OECH, then Area of ABCD rectangle is

  1. 108 ab sq. units    
  2. 116 ab sq. units    
  3. 104 sq. units    
  4. 102 sq. units    

The correct answer is: 108 ab sq. units


    OH = 9a units OE = 3b units (given)
    area of OECH=9*3 sq units
    area of OECH=27 sq units
    area of ABCD = area of 4OECH (given)
    then Area of ABCD =4*27 sq units
                                    =108 sq units

    A source S emitting sound of frequency 300Hz is fixed on block A which is attached to the free end of a spring SA as shown in figure. The dectector D fixed on block B attached to free end of spring SB detects this sound. The blocks A and B are simultaneously displaced towards each other through a distance of 1.0m and then left to vibrate. The maximum and minimum frequencies of sound detected by D, if the vibrational frequency of each block is 2Hz are Velocity of sound v =340m/s)
