The capacitor's reactance decreases as the frequency being applied to it rises. Similarly, the reactance value of the capacitor increases as the frequency across it decreases. The complex impedance of the capacitor is the name of this variation.

Because capacitance equals inductive reaction

Xc = XL

2*pi*frequency*L = 1/(2*pi*frequency*C)

frequency^2 = 1/(4*pi^2*L*C)

frequency = 1/2 * pi * sqrt(L*C)

frequency = 1/ (2*3.142*sqrt(1.1*10^-3*11*10^-6))

frequency = 1446.67 Hz

Reactance is the resistance that a capacitor and an inductor provide to an AC current in a circuit. Reactance and resistance are relatively similar, although reactance changes depending on the frequency of the ac voltage source. Ohms are used to measure it.

Either an increase in frequency or capacitance causes a reduction in capacitive reactance. As the frequency approaches zero in the limit, the capacitive reactance reaches an infinite value. Zero frequency for the generator implies the presence of a battery or other dc source.

Galileo discovered evidence in 1595 that he believed supported the idea that Earth orbits the Sun. Galileo believed that the irregular motion of Earth around the Sun was the primary cause of the tides. Galileo's explanation for the tides was incorrect, even though the idea that Earth orbits the Sun is true.

Galileo presents his three top justifications for his contention that the earth revolves around the sun. One of these is his claim that "the ebbing and flowing of the ocean tides" supports his position.

There are high and low tides. Galileo thought that the earth's rotation was what created the tides. One of his absolute worst theories is this one.

When the proton starts to move upward the direction of the magnetic force changes and when the proton moves straight up the magnetic force turns to the left.

The direction of the force is perpendicular to the direction of the magnetic field and current, as given by Fleming's left-hand rule. Here the magnetic field is to the right and the direction of the current is upward. Protons feel a force on themselves due to the magnetic field. The force on the proton is proportional to the proton's magnetic flux density and velocity.

The velocity and momentum of a proton are affected by the force acting on it. If the velocity of a charged particle is perfectly parallel to the magnetic field, the magnetic field exerts no force on the particle, so the velocity remains constant. The momentum of a proton moving freely in a magnetic field is the product of the proton's mass and the proton's velocity. As the speed of a proton moving in a magnetic field changes, so does the momentum of the proton.

The Schrödinger wave equation relates the energy of an atom to its electrons in terms of the wave function.

The Schrödinger wave equation is a partial differential equation that governs the wave function of a quantum-mechanical system. Schrödinger's model of the atom assumed the electrons could be treated at matter waves. The Schrödinger equation is conceptually the quantum counterpart of Newton's second law in classical mechanics.

Since electrons are identical to one another, the wave function of an atom with more than one electron must satisfy special conditions. The wave function of a system of identical particles depends on the coordinates of all the particles.
