the average kinetic energy

Temperature is a measure of the average kinetic energy of the particles in an object.

Explanation:

The temperature is a magnitude referred to the common notions of heat measurable by means of a thermometer. In physics, it is defined as a scalar magnitude related to the internal energy of a thermodynamic system, defined by the zero principle of thermodynamics. More specifically, it is directly related to the part of the internal energy known as kinetic energy, which is the energy associated with the movements of the system particles, either in a translational, rotational sense, or in the form of vibrations. As the kinetic energy of a system increases, it is observed that it is "hotter"; that is, its temperature is higher.

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

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
