The spectrophotometer really measures the percent of light that is transmitted through the solution. the instrument then converts %t (% transmittance) to absorbance using the relationship you determined in the prelab exercise. if the absorbance of a sample is 0.85, what is the percent light transmitted through the colored sample at this collected wavelength.

What color of light must blue light mix with to create white light? a. yellow b. white c. blue d. green

Aknife blade is a(n) a. lever b. screw c. wedge d. inclined plane

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
