5. what happens to the arrangement of water molecules as ice melts?
a molecules gain enough energy to escape as vapor.
b molecules release enough energy to escape as vapor.
c molecules gain enough energy to move from their fixed positions.
d molecules release enough energy to move from their fixed positions.

I am pretty sure the answer is B

Explanation: If not sorry bro.

the correct answer is b

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
