According to Coulomb's law, F ∝ 1/r². Reducing the distance to half increases the force by a factor of 4.

According to Coulomb's law, F ∝ q1 * q2. If both charges are doubled, the force becomes 4 times the original force.

Viruses are considered non-living entities as they cannot carry out metabolic processes independently.

Enthalpy (H) represents the total heat content of a system at constant pressure and is defined as internal energy plus pressure-volume work.

Gibberellins promote seed germination by breaking dormancy and stimulating the growth of the embryo.

Increasing temperature generally increases the rate of a chemical reaction due to higher kinetic energy.

Salivary amylase is the enzyme that begins the digestion of carbohydrates in the mouth.

During telophase, the nuclear envelope re-forms around the separated chromosomes, and spindle fibers disappear.

The buoyant force increases with the density of the fluid, as it is directly proportional to the fluid's density.

Inserting a dielectric material increases the capacitance of the capacitor by a factor equal to the dielectric constant of the material.

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.

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.

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.
