A student reading his physics book on a lake dock notices that the distance between two incoming wave crests is about 2.4 m and he then measures the time of arrival between wave crests to be 1.6 seconds. What is the approximate speed of the waves?​

v=2.4/1.6=1.5 m/s

Hope it helps

Have a good day

answer: for each 3 girls there is 2 boys . 3: 2

hope this ! (:   mark me as brainliest if you can

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
