Answer:
65m
Explanation:
Twelve waves pass a dock in 3.60 If the waves are traveling at 19.5 m/s , what is the wavelength of the waves?
Velocity of a wave is expressed as;
V = frequency × wavelength
Given
Velocity = 19.5m/s
Frequency is the number of oscillations completed in 1sec, hence
Frequency= 3.6/12
Frequency = 0.3
Wavelength = vel/freq
Wavelength = 19.5/0.3
Wavelength = 65m
Hypothesis means <span>a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation</span>

Answer:
This question is incomplete
Explanation:
This question is incomplete because the telescope's focal length was not provided. The formula to be used here is
Magnification = telescope's focal length/eyepiece's focal length
The eyepiece's focal length was provided in the question as 0.38 m.
NOTE: Magnification can be described as the power of an instrument (in this case telescope) to enlarge an object. It has no unit and thus the two focal lengths mentioned in the formula above must be in the same unit (preferably meters since one of them is in meters already).
There are four characteristics of a state. population,government,sovereignty,and territory.
