Correct option (d) Bernoulli's theorem
Explanation:
A scent sprayer is an example of fall in pressure due to increase in velocity. Also as per Bernoulli's theorem as we move along a streamline, the sum of the pressure (P), the kinetic energy per unit volume \(\left(\rho v^{2} / 2\right)\) and the potential energy per unit volume (pqy) remains a constant.
\(p+\frac{\rho v^{2}}{2}+\rho g y=\) constant
Therefore scent sprayer is based on Bernoulli's theorem.
