Answer:
The dolphin's speed is 17 mi/h
Explanation:
Use the formula for average velocity: Distance/time
then the average speed of the dolphin is 51/3 mi/h = 17 mi/h
I think the answer would be: The G-note's wavelength is longer
Here are the formula to calculate wavelength
Wavelength = Wave speed/Frequency
Which indicates that the wavelength will become larger as the frequency became smaller.

Question 1 the answer is 5 cm for the one pulley system, I just took the quiz
Question 2 is 10 cm
Explanation:
