A 1.35 kg object is placed on a scale which slides down on a 15° frictionless incline. What is the weight indicated by the scale? Consider that the scale measures only forces acting perpendicular to it and g=9.8 m/s2.

unbalanced force

explanation:

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

conduction, convection, radiation

snell's law

refractve index = sin incidence / sin refraction
