question_answer 16)

How much should the pressure on a litre of water be changed to compress it by \[14\cdot 5kg;l=r=1m;v=2\]. Bulk modulus of elasticity of water \[A=0\cdot 065\times {{10}^{-4}}{{m}^{2}}\]

Answer:

Here,\[F=mg+mr{{\omega }^{2}}=mg+mr4{{\pi }^{2}}{{v}^{2}}=\] liter = \[=14\cdot 5\times 9\cdot 8+14\cdot 5\times 1\times 4\times {{\left( 22/7 \right)}^{2}}\times {{2}^{2}}\] \[=142\cdot 1+2291\cdot 6=2433\cdot 7N\] \[Y=\frac{F}{A}\times \frac{l}{\vartriangle l}\] or \[\vartriangle l=\frac{Fl}{AY}\] \[=\frac{2433\cdot 7\times 1}{\left( 0\cdot 065\times {{10}^{-4}} \right)\times \left( 2\times {{10}^{11}} \right)}\]
