When waves travel through water, why do the moving water particles continue to return to their starting position? a. waves transfer matter, but not energy. b. waves transfer both matter and energy. c. waves transfer energy, but not matter. d. waves don't transfer matter or energy.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

it doesn't. it was imagined up in the middle ages.

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
