The magnetic field strength inside a solenoid is directly proportional to the current flowing through it. Therefore, if the current is doubled, the magnetic field strength also doubles.

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.

Reversing the direction of current in a wire reverses the direction of the magnetic field around it.

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

As the temperature increases, the kinetic energy of gas particles increases, causing them to move faster.

When a solid is heated, its particles gain energy and vibrate more vigorously, potentially leading to a change in state.

When a solid is heated, its particles gain energy and vibrate faster, which can lead to a change in state.

When a solid melts into a liquid, the particles gain energy, allowing them to overcome some of the forces holding them in fixed positions.

According to Boyle's Law, if the volume decreases and temperature is constant, the pressure increases.

The resistance of a semiconductor decreases when it is illuminated due to the generation of electron-hole pairs.

The resistance of a semiconductor decreases with an increase in temperature due to the increased number of charge carriers.

The resistance of a semiconductor decreases with an increase in temperature due to the increased number of charge carriers.

Shear modulus (G) is defined as shear stress divided by shear strain. If shear strain is constant, doubling shear stress does not change G.

The speed of light decreases when it passes from a less dense medium (air) to a denser medium (water).

During an isothermal expansion, the temperature of the gas remains constant as the system absorbs heat to do work.

In a parallel circuit, if one branch is disconnected, the total current decreases.

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

In a parallel circuit, adding more branches increases the total current.

At resonance in a parallel RLC circuit, the total current is maximum because the impedance is at its minimum.

In a parallel circuit, adding more resistors decreases the total resistance because the total resistance is given by 1/R_total = 1/R1 + 1/R2 + ...

According to Charles's Law, the volume of a gas increases with an increase in temperature at constant pressure.

Uniform pressure typically causes a decrease in volume, known as compression.

The volume of a solid generally decreases when subjected to uniform pressure, as per the bulk modulus.

Insulin is the hormone produced by the pancreas that lowers blood glucose levels by facilitating the uptake of glucose into cells.

Insulin is the hormone produced by the pancreas that lowers blood sugar levels by facilitating the uptake of glucose into cells.

25 × 3 = 75, then 100 - 75 = 25.

100 ÷ 4 = 25, then 25 + 25 = 50.
