In an h-r diagram, where can you see the spectral type of a star (whether it is an o type star or a g type star, for example)?.

explanation:

an enlarged virtual image is the answer

ice to water 1 water to vapour 2 latent heat

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
