Inserting a dielectric material between the plates of a capacitor increases its capacitance due to the material's ability to reduce the electric field.

The capacitance increases when a dielectric material is introduced, as it reduces the electric field between the plates.

The capacitance (C) of a parallel plate capacitor is inversely proportional to the distance (d) between the plates. If d increases, C decreases.

According to Ohm's Law, if the voltage increases while resistance remains constant, the current will also increase.

According to Ohm's Law, if the voltage (V) increases while resistance (R) remains constant, the current (I) will increase.

According to Ohm's Law, if the voltage (V) is tripled and resistance (R) remains constant, the current (I) will also triple (I = V/R).

In a parallel circuit, removing one branch does not affect the current in the other branches.

In a series circuit, if one component fails, the current stops flowing through the entire circuit.

When a fluid is heated, its density typically decreases as the fluid expands.

Density increases when a material is compressed, as mass remains constant while volume decreases.

The density of a solid increases when it is subjected to uniform compression.

The electric field E is directly proportional to the charge, so if the charge is doubled, the electric field also doubles.

When a capacitor is disconnected from a battery and the plates are moved further apart, the electric potential energy increases because the capacitance decreases while the charge remains constant.

According to the second law of thermodynamics, the entropy of an isolated system always increases over time.

When a balanced equation is multiplied by a factor, the equilibrium constant is raised to the power of that factor.

A catalyst speeds up both the forward and reverse reactions equally, thus it does not change the position of equilibrium or the value of Kc.

In a concave mirror, if the object distance is doubled, the image distance also changes according to the mirror formula, leading to a doubling effect.

As the object distance increases in a convex lens, the image distance also increases, moving further away from the lens.

As the object moves closer to a concave mirror, the image distance increases, and the image becomes larger and more distant.

As the object is moved closer to the focal point of a convex lens, the image distance increases and the image becomes larger and virtual.

When the object is placed beyond twice the focal length, the image formed is real, inverted, and smaller than the object.

When the object is placed within the focal length of a convex lens, the image formed is virtual and erect.

If the magnetic field is suddenly removed, the change in magnetic flux becomes zero, leading to an immediate stop in the induced current.

The induced EMF doubles if the speed of the magnet moving through the coil is doubled.

The induced emf increases when the rate of change of magnetic flux increases, according to Faraday's Law.

During an isothermal expansion of an ideal gas, the internal energy remains constant because the temperature does not change.

The magnetic field inside a solenoid is directly proportional to the current. Therefore, if the current is increased, the magnetic field also increases.

When a magnet is cut into two pieces, each piece becomes a magnet with its own north and south poles, thus maintaining the magnetic field lines.

The magnetic field strength inside a solenoid is directly proportional to the current flowing through it. Therefore, doubling the current will double the magnetic field strength.

The magnetic field strength inside a solenoid is directly proportional to the current flowing through it.
