Answer:
D. Meters/Seconds
Explanation:
The time period of a wave is measured in seconds.
A typical wave involves both time and distance. Consider a sound wave, which is basically a periodic modulation of the local air pressure. We "hear" the sound because our ears respond to the variations of pressure.
The most common metric of a sound wave is frequency. This is the rate at which the change in pressure occurs, and is measured in cycles per second, formally known as "hertz". The period is the inverse of frequency andl has the units of seconds per cycle, commonly stated simply as seconds.

let's use first equation of motion to solve this ;
Velocity after 30 seconds = 170 m/s
Your answer is c. electrons that are available for bonding.
Answer:
12010
Explanation:
Given:
power time
4,370 25
4,420 22
4,150 26
To find: difference in energy used between the dryer that uses the greatest amount of energy and the dryer that uses the least amount
Solution:
Energy = power × time
For clothes dryer x:
energy = 4370 × 25 = 109250
For clothes dryer y:
energy = 4420 × 22 = 97240
For clothes dryer z:
energy = 4150 × 26 = 107900
Dryer x uses the greatest amount of energy and dryer y uses the least amount of energy.
Difference in energy used between the dryer that uses the greatest amount of energy and the dryer that uses the least amount = 109250 - 97240 = 12010
