Biology is the term used for the study of living organisms.

Using the formula Q = kA(T1-T2)t, we find k = Q / (A(T1-T2)t) = 100 J / (1 m² * 20°C * 10 s) = 0.5 W/m°C.

The time period T is the reciprocal of frequency, T = 1/f. Thus, T = 1/20 Hz = 0.05 s.

Using Ohm's law, I = V/R = 9V / 3Ω = 3 A.

In parallel, the total current is the sum of the currents: 2 A + 2 A + 2 A = 6 A.

In a parallel circuit, the total current is the sum of the currents in each branch: 2 A + 3 A = 5 A.

Using Ohm's law, I = V/R = 9V / 3Ω = 3A.

Total resistance R = 10Ω + 5Ω = 15Ω. Current I = V/R = 30V/15Ω = 2A.

Total resistance R = 6 + 6 = 12Ω. Current I = V/R = 12V/12Ω = 1A.

Total resistance R = 5Ω + 5Ω = 10Ω; I = V/R = 15V / 10Ω = 1.5A.

Total resistance R = 3Ω + 3Ω = 6Ω. Current I = V/R = 9V/6Ω = 1.5A.

Z = √(R² + Xl²) = √(20² + 30²) = √(400 + 900) = √1300 = 36.06 ohms. I = V/Z = 240/36.06 = 6.66 A.

In parallel circuits, the total current is the sum of the currents in each branch: 2A + 3A = 5A.

In parallel circuits, the total current is the sum of the currents in each branch: 3A + 5A = 8A.

In parallel circuits, the total current is the sum of the currents in each branch: I_total = 3A + 2A = 5A.

In a parallel circuit, the total current is the sum of the currents in the branches: 2 A + 3 A = 5 A.

In a parallel circuit, the total current (I_total) is the sum of the currents in each branch: I_total = 3A + 5A = 8A.

Total current in parallel = I1 + I2 = 5A + 3A = 8A.

Total impedance Z = √(R² + (ωL)²) = √(10² + (2π(50)(20))²). Calculate to find current.

At the highest point of a pendulum's swing, all the mechanical energy is potential energy, and kinetic energy is zero.

At maximum displacement, the total mechanical energy of a simple harmonic oscillator is at its maximum, as all energy is potential.

The total mechanical energy E is given by E = (1/2)kA². Therefore, E = (1/2)(100)(0.1)² = 0.5 J.

At the highest point of a projectile's trajectory, the kinetic energy is minimum (zero at the peak) and potential energy is maximum, thus total mechanical energy is maximum potential energy.

The total mechanical energy of an object in free fall is conserved, meaning it remains constant as potential energy converts to kinetic energy.

Moles = Molarity * Volume = 3 mol/L * 2 L = 6 moles.

The real power (P) can be calculated using P = Power Factor × Apparent Power. Therefore, P = 0.6 × 100 VA = 60 W.

Total resistance R = 10Ω + 10Ω = 20Ω. Power P = V²/R = 20² / 20 = 20W.

Total resistance R = 5Ω + 5Ω = 10Ω; Power P = V²/R = 30²/10 = 90W.

In series, R_eq = R1 + R2 = 10Ω + 20Ω = 30Ω.

In series, R_eq = R1 + R2 = 10Ω + 20Ω = 30Ω.
