Power P = V^2/R = (12V)^2/4Ω = 36W.

Power (P) = I^2 * R = 5^2 * 4 = 25 * 4 = 100W.

Total power P = P1 + P2 = 5 D - 3 D = 2 D.

In series, total resistance (R_total) = R1 + R2 = 10Ω + 5Ω = 15Ω.

1/R_eq = 1/12 + 1/4 => R_eq = 3 ohms.

In series, total resistance R_total = R1 + R2 = 12Ω + 4Ω = 16Ω.

Total resistance R = R1 + R2 = 3Ω + 5Ω = 8Ω.

1/R_eq = 1/R1 + 1/R2 = 1/10 + 1/10 = 2/10. Thus, R_eq = 10/2 = 5 ohms.

In series, R_eq = R1 + R2 = 10 + 10 = 20 ohms.

1/R_eq = 1/R1 + 1/R2 = 1/12 + 1/12 = 2/12. Thus, R_eq = 12/2 = 6 ohms.

In series, R_eq = R1 + R2 = 8 + 8 = 16Ω.

1/R_eq = 1/5 + 1/10 => R_eq = 3.33 ohms.

In series, R_eq = R1 + R2 = 8 + 12 = 20Ω.

Using the formula V = I * R_eq. First, find R_eq = 1 / (1/10 + 1/20) = 6.67Ω. Then, V = 3A * 6.67Ω = 20V.

In a series circuit, the total voltage is equal to the voltage of the battery, which is 9V.

The trace of A is the sum of the diagonal elements: 1 + 5 + 9 = 15.

Atomic radius increases down a group due to the addition of electron shells.

The atomic radius increases as you move down the group of alkali metals.

Electronegativity increases from left to right across a period.

Ionization energy decreases as you move down the group in s-block elements due to increased atomic size.

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.

B OR C = 0 OR 1 = 1. Then, A AND 1 = 1 AND 1 = 1.

The typical band gap of germanium is approximately 0.66 eV.

The typical range of the energy band gap for semiconductors is between 0.5 eV and 2.5 eV.

To convert grams to kilograms, divide by 1000. The uncertainty in kilograms is 0.5 g / 1000 = 0.0005 kg.

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.
