Unformatted text preview: different place. The two scales are simply offset by 273.15 degrees. The zero of the Kelvin scale is absolute zero, which is the lowest possible temperature that a substance can be cooled to. Several physics formulas involving temperature only make sense when an absolute temperature (a temperature measured in Kelvin) is used, so the fact that the Kelvin scale is an absolute scale makes it very convenient to apply to scientific work. two control rods are attached at A to lever AB. using trigonometry and knowing that the force in the left-hand rod is F= 30lb two forces P and Q are applied as shown at point A of a hook support. Knowing that P=45 lb...
