Ionization energy decreases down the group for alkali metals.

Metallic character decreases from left to right across a period.

First, evaluate B OR C, which is 0 OR 1 = 1. Then, A AND 1 = 1 AND 1 = 1.

Using Heisenberg's uncertainty principle, ΔxΔp ≥ ħ/2, we find Δx ≥ ħ/(2Δp) = (1.055 x 10^-34)/(2 x 1.0 x 10^-24) = 5.27 x 10^-11 m.

The uncertainty principle states that the product of the uncertainties in position (Δx) and momentum (Δp) is greater than or equal to ħ/2.

The unit of angular momentum is kg·m^2/s.

The unit of capacitance is the Farad (F), which is defined as one coulomb per volt.

The electric field strength is defined as the force per unit charge, which is measured in volts per meter (V/m).

The unit of electric potential is the Volt (V), which is defined as one Joule per Coulomb.

The unit of electrical charge is the Coulomb.

The unit of electrical resistance is Ohm.

The unit of entropy is Joules per mole per Kelvin (J/mol·K).

The unit of impedance in an AC circuit is Ohm, which is the same as resistance.

The unit of magnetic field strength is Tesla (T), which is derived from the Biot-Savart Law.

The unit of magnetic field strength is Tesla (T), which is derived from Ampere's Law.

The unit of magnetic field strength is the Tesla (T).

The unit of magnetic field strength is the Tesla (T), which is defined as one weber per square meter.

The unit of magnetic flux is the Weber (Wb), which is defined as the amount of magnetic field passing through a given area.

The SI unit of pressure is Pascal (Pa), defined as one newton per square meter (N/m²).

The unit of resistance is Ohm, which is defined as the resistance between two points when a constant potential difference of one volt produces a current of one ampere.

The unit of resistivity is Ohm-meter (Ω·m).

Sound intensity is measured in decibels (dB).

Surface tension is defined as force per unit length, hence its unit is Newton per meter (N/m).

The unit of the magnetic field as defined by the Biot-Savart Law is Tesla.

The unit of the rate constant for a second-order reaction is L²/mol²·s.

The unit of thermal conductivity is Watts per meter per Kelvin (W/m·K).

The unit of torque in the SI system is Newton-meter (Nm).

Young's modulus is defined as stress divided by strain and is measured in Pascals (Pa).

Unit vector = (3, 4, 0) / √(3^2 + 4^2) = (3, 4, 0) / 5 = (0.6, 0.8, 0).

Unit vector = (4/5, 3/5) since magnitude = 5.
