Understanding the Question

To answer this question, we need to look into the principles of physics that relate to fluid dynamics and pressure. We are given four laws to consider:

1. Bernoulli's Law
2. Boyle's Law
3. Pascal's Law
4. Charles's Law

Relevant Concepts

1. Bernoulli's Law: This principle states that in a streamlined flow, an increase in the speed of the fluid occurs simultaneously with a decrease in pressure or potential energy. This can explain why covering the end of a hose increases water flow speed.

2. Boyle's Law: Refers to the relationship between pressure and volume of a gas at constant temperature.

3. Pascal's Law: States that pressure applied to a confined fluid is transmitted undiminished in all directions throughout the fluid.

4. Charles's Law: Relates to the volume and temperature of a gas at constant pressure.

Analysis

When the end of the hose is covered, the area for water to exit is decreased. According to Bernoulli's Law, as the water flow is constricted, the velocity of the moving water must increase to maintain continuity (the principle of conservation of mass). This increased velocity occurs because the pressure at the narrowed end decreases, causing the water to accelerate.

Verification of Concepts

• Bernoulli's Principle is specifically applicable in this case, as it directly relates to fluid speed and pressure variations. The other laws do not apply to the scenario of fluid flow in a hose.

Final Answer

The principle that explains why covering the end of the hose causes the water to flow faster is Bernoulli's Law.
