Answer:
Is where two or more inductors are “linked” so that voltage is induced in one coil proportional to the rate-of-change of current in another
In astronomy, Johannes Kepler published his three laws about planetary motion. It is one of the most important things in astronomy. So Kepler gives three laws about planetary motion.
<h3>What is motion?</h3>
Motion is a physical term in physics. If a particle of mass m and affected by some force F then it change its position in many different way. That is the motion of the object. It is a vector quantity.
<h3>What is Kepler's three laws?</h3>
In astronomy, Johannes Kepler published his three laws about planetary motion between 1609 and 1619. This shows about motion describe the orbits of planets around the Sun. So the three motions are shown following,
<u>First law</u>: Every planet in solar system that moves in a elliptical orbits where the sun always in the center of the motion.
<u>Second law</u>: Every planet covers the same amount of distance in a constant time no matter where the orbit of the planet placed. That means the velocity of every planet is not same. It varies along with the orbit. But every time the change of area is constant.
<u>Third law</u>: The orbital period of the planet is proportional with the cube of the semi major axis of the planet. It can be shown mathematically,
p²∝a³
Where we know,
p= The orbital period of the planet.
a= the semi major axis of the planet.
From the discussion we can easily shown that there are three laws of Kepler about planetary motion.

Answer:
Capacitance is the ratio of the charge to the potential difference. How is the charge stored on a capacitor related to the capacitance of the capacitor and the potential difference across the capacitor? The charge equals the product of the capacitance and the potential difference.

Independent, and inverse means if one variable increases then the other decreases, direct is when they both go up or down together.
Answer: when the wave encounters something, it can bounce (reflection) or be bent (refraction). In fact, you can "trap" waves by making them bounce back and forth between two or more surfaces. Musical instruments take advantage of this; they produce pitches by trapping sound waves.
Explanation: Any bunch of sound waves will produce some sort of noise. But to be a tone - a sound with a particular pitch - a group of sound waves has to be very regular, all exactly the same distance apart. That's why we can talk about the frequency and wavelength of tones.
