The effect of temperature on resistance depends on the material; for most conductors, resistance increases with temperature.

For most conductors, resistance increases with temperature due to increased lattice vibrations that impede electron flow.

The resistance of most conductive materials increases with temperature due to increased atomic vibrations that impede electron flow.

The speed of sound in air increases with an increase in temperature.

As temperature increases, the kinetic energy of the molecules increases, leading to a decrease in cohesive forces and thus a decrease in surface tension.

Surface tension decreases with an increase in temperature due to increased molecular motion.

According to Raoult's Law, the vapor pressure of a solvent increases with an increase in temperature.

For most liquids, viscosity decreases with an increase in temperature due to increased molecular motion.

The +M effect stabilizes the carbocation by donating electron density through resonance.

The -I effect increases acidity by stabilizing the negative charge on the conjugate base.

Electron-withdrawing groups (-I) increase the acidity of compounds by stabilizing the negative charge on the conjugate base.

The -M effect can stabilize a carbocation by delocalizing the positive charge.

-M groups destabilize carbocations by withdrawing electron density through resonance.

An external torque changes the angular momentum of the system.

Adding a resistor in parallel decreases the total resistance, which increases the total current according to Ohm's law.

Adding more resistors in series increases the total resistance, as total resistance is the sum of individual resistances.

Adding a resistor in parallel decreases the total resistance of the circuit.

Adding more resistors in parallel decreases the total resistance of the circuit.

Adding resistors in parallel decreases the total resistance.

In series, the total resistance increases as more resistors are added.

Total resistance increases when resistors are added in series.

The efficiency of a Carnot engine is given by the formula: efficiency = 1 - (T2 / T1), where T1 is the higher temperature and T2 is the lower temperature.

The electric field due to an infinitely long charged wire is given by E = λ/(2πε₀d).

Electric field E = k * q / r^2 = (9 × 10^9) * (1 × 10^-6) / (1)^2 = 9 × 10^3 N/C.

The electric field at a distance r from a uniformly charged disk is given by E = σ/(2ε₀) * (1 - r/√(R² + r²)).

For r > R, the electric field behaves as if all the charge were concentrated at the center, thus E = Q/(4πε₀r²).

The electric field due to an infinite line charge is given by E = λ/2πε₀r.

The electric field due to an infinitely long line of charge is given by E = λ/(2πε₀r), directed radially outward from the line.

The electric field due to a positive charge is directed away from the charge.

The electric field just outside a charged conductor is given by E = σ/ε₀, where σ is the surface charge density.
