Question

Figure shows a stream of fluid emerging from a tube in the base of an open fixed tank. The expression of ‘y’ (Maximum height traveled by jet of water) is

  1. h    
  2. h sin to the power of 2 end exponent invisible function application theta    
  3. h cos to the power of 2 end exponent invisible function application theta    
  4. fraction numerator h over denominator sin to the power of 2 end exponent invisible function application theta end fraction    

The correct answer is: h sin to the power of 2 end exponent invisible function application theta


    y equals fraction numerator u subscript y end subscript superscript 2 end superscript over denominator 2 g end fraction
    u equals square root of 2 g h end root u subscript y end subscript equals square root of 2 g h end root sin invisible function application theta rightwards double arrow y equals fraction numerator open parentheses square root of 2 g h end root sin invisible function application theta close parentheses to the power of 2 end exponent over denominator 2 g end fraction equals h sin to the power of 2 end exponent invisible function application theta
