Real-World Scientific Problems

Step-by-step solutions to common scientific calculations

Kinematics: Free Fall

Problem: A ball is dropped from a 45m tall building. How long does it take to hit the ground?

Given: h₀ = 45m, v₀ = 0, g = 9.8 m/s²
Using: h = h₀ + v₀t - ½gt²
0 = 45 + 0 - 4.9t²
t² = 45/4.9 = 9.18
✓ Answer: t = 3.03 seconds

Stoichiometry: Mole Calculations

Problem: How many grams of CO₂ are produced from 25g of C₂H₆ in complete combustion?

Equation: 2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
Molar mass C₂H₆ = 30.07 g/mol
Molar mass CO₂ = 44.01 g/mol
25g C₂H₆ × (1 mol/30.07g) × (4 mol CO₂/2 mol C₂H₆) × (44.01g/mol)
✓ Answer: 73.1g CO₂

Circuit Analysis: Ohm's Law

Problem: Find the current in a circuit with 12V source and three resistors in series.

Given: V = 12V, R₁ = 100Ω, R₂ = 220Ω, R₃ = 330Ω
Total resistance: Rₜ = R₁ + R₂ + R₃
Rₜ = 100 + 220 + 330 = 650Ω
Current: I = V/Rₜ = 12/650
✓ Answer: I = 18.5 mA

Biology: Population Growth

Problem: A bacterial population doubles every 20 minutes. Starting with 100 bacteria, how many after 2 hours?

Using exponential growth: N(t) = N₀ × 2^(t/T)
Where: N₀ = 100, t = 120 min, T = 20 min
N(120) = 100 × 2^(120/20)
N(120) = 100 × 2⁶ = 100 × 64
✓ Answer: 6,400 bacteria

Wave Physics: Frequency & Wavelength

Problem: A sound wave has frequency 440 Hz. What is its wavelength in air at 20°C?

Given: f = 440 Hz, v = 343 m/s (speed of sound at 20°C)
Using: v = fλ
λ = v/f = 343/440
✓ Answer: λ = 0.78 meters

Thermodynamics: Heat Transfer

Problem: How much heat is needed to raise 2kg of water from 20°C to 100°C?

Given: m = 2kg, ΔT = 80°C, c = 4186 J/(kg·°C)
Using: Q = mcΔT
Q = 2 × 4186 × 80
Q = 669,760 J
✓ Answer: Q = 670 kJ
