C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Correct Answer: C
Solution :
According to Bernoulli's equation, \[\frac{P}{\rho }+hg+\frac{1}{2}{{v}^{2}}=\] constant Thus, total energy of the injectable medicine depends upon second power of the velocity and first power of the pressure. It implies that total energy of the injectable medicine has greater dependence on its velocity. Therefore, a doctor adjust the flow of the medicine with the help of the size of the needle of the syringe \[{{a}_{1}}{{v}_{1}}={{a}_{2}}{{v}_{2}})\] rather than the thumb pressure.You need to login to perform this action.
