Which of these statements best describes the role of creativity in science? a. it scientists prove non-observable theories b. it scientists make conclusions non-testable c. it scientists give valid scientific explanations. d. it scientists create theories which are universal.

D. It helps scientists create theories which are universal.

Explanation:

Scientists use their creativity to formulate explanations of natural phenomena, building well-structured theories that then have to be scrupulously tested to see if they correspond to real life. These explanations are well informed, but the fact that they are mainly products of the imagination cannot be ignored.

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

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
