Step 1: The given equation is a product of two factors. For the equation to hold, either one or both factors must be zero.
Step 2: Solve each factor separately: 1. \( \frac{9}{x} - \frac{9}{\sqrt{x}} + 2 = 0 \) 2. \( \frac{2}{x} - \frac{7}{\sqrt{x}} + 3 = 0 \)
Step 3: Solve each of the resulting equations for \( x \), and ensure that the solutions satisfy the conditions of the problem.
Step 4: After solving both equations, you will find that there are 2 distinct solutions for \( x \). Thus, the correct answer is (3).

The molarity of a 70% (mass/mass) aqueous solution of a monobasic acid (X) is:
The velocity-time graph of an object moving along a straight line is shown in the figure. What is the distance covered by the object between \( t = 0 \) to \( t = 4s \)?
A proton is moving undeflected in a region of crossed electric and magnetic fields at a constant speed of \( 2 \times 10^5 \, \text{m/s} \). When the electric field is switched off, the proton moves along a circular path of radius 2 cm. The magnitude of electric field is \( x \times 10^4 \, \text{N/C} \). The value of \( x \) is \(\_\_\_\_\_\). (Take the mass of the proton as \( 1.6 \times 10^{-27} \, \text{kg} \)).
