Energy is measured in Joules, and 1 Joule is defined as 1 Newton-meter, hence both A and B are correct.

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

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

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 number of turns per unit length. Therefore, if the number of turns per unit length is increased, the magnetic field strength also increases.

The magnetic field strength inside a solenoid increases with the number of turns, as it is directly proportional to the number of turns per unit length.

When the current in a solenoid is reversed, the direction of the magnetic field also reverses.

When the current in a wire is reversed, the direction of the magnetic field also reverses.

The magnetic field around a long straight conductor decreases with distance. Specifically, it is inversely proportional to the distance from the conductor.

Removing a branch in a parallel circuit decreases the total current.

The base unit of temperature in the SI system is Kelvin (K).

C = Q/V = 10 × 10^-6 C / 5 V = 2 × 10^-6 F = 2 µF.

Capacitive reactance Xc = 1 / (2πfC) = 1 / (2π * 60 * 10e-6) = 265.26Ω.

ΔS = Q/T = 2260 kJ / 373 K = 6.06 kJ/K.

ΔU = nCvΔT. For a monatomic gas, Cv = (3/2)R. ΔU = 1 * (3/2)(8.31 J/mol K)(600 - 300) = 900 J.

Change in internal energy (ΔU) = Q - W = 300 J - 100 J = 200 J.

Using the first law of thermodynamics, ΔU = Q - W = 200 J - 50 J = 150 J.

Using the first law of thermodynamics: ΔU = Q - W = 300 J - 100 J = 200 J.

λ = h / p = h / (mv) = 6.63 x 10^-34 / (9.11 x 10^-31 * 1 x 10^6) = 6.63 x 10^-24 m.

The direction of the magnetic field around a straight conductor carrying current is counterclockwise when viewed from the positive end of the conductor.

The direction of the magnetic field inside a bar magnet is from the north pole to the south pole.

Inserting a dielectric material increases the capacitance of a capacitor by reducing the electric field within it.
