NEED HELP ASAP The distance from the midpoint to the height of a crest is known as the

1) amplitude
2)crest
3)wavelength
4)frequency

Wavelength!

Explanation:

At least I think? Or wavelength might be crest to crest! Sorry if I'm incorrect. Let me know how I did!

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

i think the answer is tomato juice? not entirely sure though
