Example:

Question: Calculate the acceleration of a car that increases its speed from 0 to 20 m/s in 10 seconds.

Solution:

Using the formula \( a = (v - u) / t \),

where \( u = 0 \) m/s (initial velocity), \( v = 20 \) m/s, and \( t = 10 \) s,

\( a = (20 - 0) / 10 = 2 \) m/s².

The memorandum emphasizes the importance of units, proper substitution, and significant figures.

Waves and Vibrations

Solutions include:

• Calculations involving wave speed, frequency, and wavelength
• Understanding properties of different wave types

Solution:

Using the formula:

\( \frac{1}{R_{eq}} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3} \)

\( \frac{1}{R_{eq}} = \frac{1}{2} + \frac{1}{4} + \frac{1}{6} = \frac{6}{12} + \frac{3}{12} + \frac{2}{12} = \frac{11}{12} \)

Therefore, \( R_{eq} = \frac{12}{11} \approx 1.09 \) Ω.
