A) A directional compass
B) a door catch or latch on a kitchen cabinet
C) An air filter that traps dust and iron particles
D) Two socks stuck together coming out of a clothes dryer

Answer 1

Here are the forces at work in each device:

1. **A) A directional compass** - This device operates based on **magnetic force**. The needle aligns itself with the Earth's magnetic field.

2. **B) A door catch or latch on a kitchen cabinet** - This device utilizes **mechanical force** (specifically, the force of a spring or gravity) to hold the door closed.

3. **C) An air filter that traps dust and iron particles** - This device operates based on **electrostatic force**. The filter often uses static electricity to attract and trap particles.

4. **D) Two socks stuck together coming out of a clothes dryer** - This situation is primarily due to **frictional force**, which can cause items to cling together when dried.

So the forces for each device are:

- A: Magnetic force
- B: Mechanical force
- C: Electrostatic force
- D: Frictional force
