The pulling force that moves water upward in xylem vessels is primarily due to:

The correct answer is C: Transpirational pull (tension) in xylem. Cohesion-tension theory explains that water is pulled upward due to transpirational pull creating negative pressure in xylem.

The phenomenon where plants lose water as liquid droplets from leaf margins is called:

The correct answer is B: Exudation. Exudation or guttation occurs when root pressure forces water out through specialized pores (hydathodes) as liquid water droplets, typically observed in early morning.

A transformer has a primary coil with 500 turns and secondary coil with 100 turns. If the primary voltage is 220V, what is the secondary voltage?

The correct answer is B: 44 V. # Transformer Voltage Calculation A transformer changes voltage based on the ratio of turns in its primary and secondary coils. **Step 1: Identify the Transformer Equation** For an ideal transformer, the voltage ratio equals the turns ratio between the primary and secondary coils. $$\frac{V_{\text{p

A spring with spring constant k = 100 N/m is compressed by 0.2 m. What is the elastic potential energy stored?

The correct answer is B: 2 J. Elastic potential energy U = ½kx². U = ½ × 100 × (0.2)² = 50 × 0.04 = 2 J.

A convex lens of focal length 15 cm forms an image at distance 30 cm from the lens. What is the object distance?

The correct answer is D: -30 cm. The lens formula relates object distance, image distance, and focal length for any lens system. Step 1: [Identify Given Values] We are given the focal length (f) = 15 cm and image distance (v) = 30 cm. We need to find the object distance (u) using the lens formula. $$\text{Given: } f = 15 \text{ cm,
