Question

Which of the substance A comma blank B or C has the highest specific heat? The temperature v s time graph is shown

  1. A    
  2. B    
  3. C    
  4. All have equal specific heat    

The correct answer is: C


    Substances having more specific heat take longer time to get heated to a higher temperature and longer time to get cooled.

    If we draw a line parallel to the time axis then it cuts the given graphs at three different points. Corresponding points on the times axis shows that
    t subscript C end subscript greater than t subscript B end subscript greater than t subscript A end subscript rightwards double arrow C subscript C end subscript greater than C subscript B end subscript greater than C subscript A end subscript

    The pole of the straight line 9x + y – 28 = 0 with respect to the circle 2 x squared plus 2 y squared minus 3 x plus 5 y minus 7 equals 0 is

    Pole and polar are one of the important parts of the circle, many questions can be based on these parts. It should be remembered that while writing the equation of polar for a pole, the coefficients of square terms in the equation of the circle is one. If the equation of the circle does not have coefficients as one, then make it one before solving the question.
