What does the kinetic theory explain? Heat is due to temperature.

Heat is due to potential energy.

Heat is due to the motion of molecules.

Heat is due to Pascal´s principle.

Your answer would be option 3/C

Heat is due to the motion of molecules.

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
