Wave Motion, Yes or No? FM radio: \( \qquad \) A car going \( 70 \mathrm{~m} / \mathrm{s} \) : \( \qquad \) Clock pendulum: \( \qquad \) Ocean waves: \( \qquad \) Music: \( \qquad \) A bulldozer: \( \qquad \) Earthquakes: \( \qquad \) Cellphones: \( \qquad \)

To determine whether each item listed involves wave motion, we can analyze each one based on the characteristics of wave motion, which typically involves the transfer of energy through oscillations or disturbances in a medium. 1. **FM radio**: Yes, FM radio uses electromagnetic waves to transmit information. 2. **A car going \( 70 \mathrm{~m/s} \)**: No, a car moving at a constant speed does not involve wave motion; it is simply a motion of an object. 3. **Clock pendulum**: Yes, a clock pendulum exhibits oscillatory motion, which is a form of wave motion. 4. **Ocean waves**: Yes, ocean waves are a classic example of wave motion, involving the movement of water. 5. **Music**: Yes, music is produced by sound waves, which are vibrations traveling through a medium (usually air). 6. **A bulldozer**: No, a bulldozer moving does not involve wave motion; it is a mechanical motion of an object. 7. **Earthquakes**: Yes, earthquakes generate seismic waves that travel through the Earth. 8. **Cellphones**: Yes, cellphones use electromagnetic waves to transmit signals. In summary: - FM radio: Yes - A car going \( 70 \mathrm{~m/s} \): No - Clock pendulum: Yes - Ocean waves: Yes - Music: Yes - A bulldozer: No - Earthquakes: Yes - Cellphones: Yes
