In a surface wave (like water) the water goes up and down, but the wave travels across (parallel to) the surface.
Answer:
If the avg speed is 10mi/h and you want to know how long it will take to run 2.5mi/h you put that as a ratio 2.5/10 which is 1/4 of an hour so it will take 15 minutes to run 2.5 miles
Explanation:
Answer: 0.5 seconds
Explanation:
Given that:
Frequency of the George Washington Bridge F = 2.05 Hz
Period T = ?
Recall that frequency is the number of cycles a wave can complete in one second. Hence, frequency is the inverse of period.
i.e F = 1/T
2.05Hz = 1/T
T = 1/2.05Hz
T = 0.488 seconds (Rounded to the nearest tenth as 0.5seconds)
Thus, the period of the George Washington Bridge is 0.5 seconds
