Answer 1

1. You inherited tallness from your father. Physical traits are transmitted from parents to offspring through **Genes**.

2. When you carry a heavy load with one arm, you tend to hold your free hand away from your body in order to **Change the center of the gravity of your body and load**.

3. Jane placed some mothballs inside her cabinet. After a week they were all gone. What happened to the mothballs? **They sublimed**.

4. Which is the destructive fishing method wherein fishes are driven out of coral reef by pounding the corals with a heavy weight? **Muro-ami**.

5. The voltage across a transformer primary coil that has 100 turns in 10V. What is the voltage across the secondary coil that has 20 turns? Using the transformer equation (Vp/Vs = Np/Ns), we have:

- Vp = 10V,
- Np = 100 turns,
- Ns = 20 turns.

So,

\[
\frac{10V}{Vs} = \frac{100}{20}
\]

Solving for Vs:

\[
Vs = 10V \times \frac{20}{100} = 2V
\]

Therefore, the voltage across the secondary coil is **2V**.
