Desorption is the process of removing adsorbed molecules from a surface, while adsorption is the process of molecules adhering to a surface.

Biology is the scientific 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.

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 = 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: 3A + 5A = 8A.

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 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.

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

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.

In a series circuit, total resistance (R_total) is the sum of individual resistances: R_total = R1 + R2 + R3 = 2Ω + 3Ω + 5Ω = 10Ω.

In series, R_eq = R1 + R2 = 4Ω + 4Ω = 8Ω.

For parallel resistors, 1/R_eq = 1/R1 + 1/R2 = 1/4 + 1/6. Finding a common denominator gives R_eq = 2.4Ω.

In series, total resistance R = R1 + R2 = 4 Ω + 6 Ω = 10 Ω.

The atomic radius increases as you move down the alkali metal group due to the addition of electron shells.

The reactivity of alkali metals increases down the group due to the decrease in ionization energy.

The Tyndall effect is the scattering of light by colloidal particles, making the path of the light visible.
