Bulk modulus (K) = -ΔP / (ΔV/V) = -50 MPa / (-0.002 m³ / 1 m³) = 25000 MPa = 25 GPa.

Using the formula C = Q/V, we have C = 6μC / 3V = 2μF.

The capacitance of a spherical capacitor is given by C = 4πε₀ab/(b-a).

A neutron has no charge; it is electrically neutral.

A proton carries a positive charge of +1 elementary charge.

1 coulomb is the charge that passes through a conductor when a current of 1 ampere flows for 1 second.

One coulomb is equivalent to approximately 6.25 x 10^18 electrons.

One coulomb is equivalent to approximately 6.25 x 10^18 electrons.

The continuity equation states that the product of the cross-sectional area (A) and the velocity (V) of a fluid remains constant along a streamline.

The critical angle θc can be calculated using sin(θc) = 1/n. Thus, θc = sin^(-1)(1/1.5) = sin^(-1)(0.6667) ≈ 41.81 degrees, which is closest to 60 degrees.

Using Ohm's law, I = V/R = 20V/10Ω = 2 A.

The dielectric constant (κ) of a vacuum is defined as 1, which serves as the reference for other materials.

The dimension of energy is M^1L^2T^-2.

The dimension of force is M^1L^1T^-2.

Velocity is defined as displacement per unit time, hence its dimension is M^0L^1T^-1.

The dimension of work is M^1L^2T^-2.

Force has the dimensional formula [M^1 L^1 T^-2].

Conventional current is defined as the flow of positive charge, which is from positive to negative.

Using the right-hand rule, if the current flows in a counterclockwise direction when viewed from above, the magnetic field direction is out of the plane.

Using the right-hand rule, if the current flows in a counterclockwise direction, the magnetic field inside the loop points out of the plane.

The magnetic field inside a current-carrying solenoid is directed from the north pole to the south pole of the solenoid.

The direction of the magnetic field produced by a current-carrying wire depends on the direction of the current, as determined by the right-hand rule.

When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitances, thus it increases.

Introducing a dielectric material between the plates of a capacitor increases its capacitance by a factor equal to the dielectric constant (κ) of the material.

Inductive reactance is directly proportional to frequency; as frequency increases, inductive reactance increases.

Increasing resistance in a series RLC circuit at resonance will decrease the current, as the impedance increases.

Increasing temperature generally decreases the viscosity of liquids, allowing them to flow more easily.

Increasing the area A of the plates increases the capacitance, as C = εA/d.

In a capacitive AC circuit, increasing the capacitance decreases the capacitive reactance (X_C), which increases the current (I = V/X_C).

Increasing the capacitance decreases the capacitive reactance (X_C = 1/(2πfC)), which can lead to an increase in current.
