Like a transverse wave, a longitudinal wave has

the second.

Explanation:

All waves have frequency, wavelength, speed and amplitude. The amplitudes of longitudinal and transverse waves are measured differently,

13.33m/s

Explanation:

The average velocity is the ratio of total distance traveled to the total time taken to complete the distance. The International System of Units (SI) unit of velocity is the meter per second (m/s). The Velocity is given by the equation:

Velocity = total distance traveled / total time taken

The total distance traveled = Distance traveled by horse + distance traveled by truck + remaining distance traveled = 100 m + 500 m + 1000 m = 1600 m

Total time taken = 120 s

Velocity = total distance traveled / total time taken = 1600 m / 120 s = 13.33 m/s

Velocity = 13.33 m/s
