The term 'adsorption capacity' refers to the amount of solute that can be adsorbed per unit mass of adsorbent.

Biology is the scientific study of living organisms.

10 g of Na = 0.434 moles. 2Na + H2SO4 → Na2SO4 + H2. 0.434 moles of Na2SO4 = 0.434 * 142 g = 61.6 g.

23 g of Na = 1 mole. 1 mole of Na produces 1 mole of NaCl = 58.5 g.

23 g of Na = 1 mole. 1 mole of Na produces 1 mole of NaCl = 58.5 g.

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.

Threshold frequency (ν₀) = Work function (Φ) / h = 4.5 eV / (4.14 x 10^-15 eV·s) = 5.4 x 10^14 Hz.

The threshold of hearing is defined as 0 dB, which corresponds to the faintest sound that can be heard by the average human ear.

The total angular distance is 30° + 30° = 60°. The time difference is 60 / 15 = 4 hours.

The total difference in longitude is 75 + 15 = 90 degrees. Therefore, the time difference is 90/15 = 6 hours.

Time period (T) = 2π/ω_n = 2π/10 = 0.2π ≈ 0.628 s.

Time period (T) = 2π/ω_n = 2π/3 rad/s = 2π/3.

The time period T of a simple pendulum is given by T = 2π√(L/g), where L is the length of the pendulum and g is the acceleration due to gravity.

The passage critically examines the negative effects of social media on genuine communication.

The author expresses an optimistic view about the potential of technology to improve lives.

The author maintains an optimistic tone, suggesting that change is possible and necessary.

The tone is formal, as it discusses serious topics in a structured manner.

Torque = Force × Distance = 12 N × 0.25 m = 3 Nm.

Torque = Force × Distance = 8 N × 0.75 m = 6 Nm.

Torque = Force × Distance = 60 N × 0.75 m = 45 Nm.

Torque = Force × Distance = 60 N × 0.75 m = 45 Nm.

Torque (τ) = Force (F) × Distance (r) = 10 N × 2 m = 20 Nm.

Torque = Force × Distance × sin(θ) = 15 N × 0.5 m × sin(90°) = 15 Nm.

Torque = Force × Distance × sin(90°) = 25 N × 0.5 m × 1 = 12.5 Nm.

In parallel, the total capacitance is the sum: C_total = C1 + C2 = 3 µF + 6 µF = 9 µF.

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

Using Ohm's Law, I = V / R. Here, I = 12 V / 4 ohms = 3 A.

Using Ohm's Law (I = V/R), the current is I = 12V / 4Ω = 3A.
