What is bernoullis principle?
The relationship between the velocity and pressure exerted by a moving liquid is described by the Bernoulli's principle: as the velocity of a fluid increases, the pressure exerted by that fluid decreases.Airplanes get a part of their lift by taking advantage of Bernoulli's principle. Race cars employ Bernoulli's principle to keep their rear wheels on the ground while traveling at high speeds.Bernoulli's principle, physical principle formulated by Daniel Bernoulli that states that as the speed of a moving fluid (liquid or gas) increases, the pressure within the fluid decreases. The phenomenon described by Bernoulli's principle has many practical applications; it is employed in the carburetor and the atomizer, in which air is the moving fluid, and in the aspirator, in which water is the moving fluid. In the first two devices air moving through a tube passes through a constriction, which causes an increase in speed and a corresponding reduction in pressure. As a result, liquid is forced up into the air stream (through a narrow tube that leads from the body of the liquid to the constriction) by the greater atmospheric pressure on the surface of the liquid. In the aspirator air is drawn into a stream of water as the water flows through a constriction. Bernoulli's principle can be explained in terms of the law of conservation of energy (see conservation laws, in physics). As a fluid moves from a wider pipe into a narrower pipe or a constriction, a corresponding volume must move a greater distance forward in the narrower pipe and thus have a greater speed. At the same time, the work done by corresponding volumes in the wider and narrower pipes will be expressed by the product of the pressure and the volume. Since the speed is greater in the narrower pipe, the kinetic energy of that volume is greater. Then, by the law of conservation of energy, this increase in kinetic energy must be balanced by a decrease in the pressure-volume product, or, since the volumes are equal, by a decrease in pressure.
Which does not state a principle related to why ground wires are in effective safety device?
Electronic devices are protected from power surges by having insulated wires
Whose principle explains what happens when force is applied to a confined fluid?
Pascal's Law (hydraulic pressure) states that force applied to a confined fluid causes it to exert pressure equally throughout the fluid. This can be used to multiply a small force exerted over a large distance to move a large mass a smaller distance.

Avogadro's principle canbe applied when these 3 measurements are the same?
Avogadro's principle can be applied when the temperature, volume and pressure are the same. This principle was named after Amedeo Avogadro.
How do you use a water pressure pump?
There are many different ways to use a 'water pressure pump' . Any water pump will build up pressure, this is the basic principle of well pumps, and similar. Most are 'used' by a pressure switch which turns the pump on when pressure decreases to a certain point.

How does water get to the leaves in the top trees against the force of gravityname the property responsible for this and explain how it works?
Actually is by the help of the physical principle and property called "Turgor pressure.
How do airplanes use Bernoulli's Principle?
Bernoulli's Principle states that where the speed of a fluid is fast, the pressure is low, and where the speed of a fluid is slow, the pressure is high. Airplanes use Bernoulli's Principle in lift. The top of an airplane wing is longer than the bottom. This causes molecules to move faster in order to stay together, creating an area of low pressure. Underneath the wing, the molecules move more slowly because there are more molecules in a smaller area- this creates an area of high pressure. Since air moves from high pressure to low pressure, the wings are forced upwards, creating lift.
