Aspectrophotometer measures the transmittance or the absorbance, or both, of a particular wavelength of light after it has passed through a liquid sample. before the transmittance or absorbance of the sample is measured, a cuvette filled only with solvent, called the blank, is placed in the spectrophotometer and measured. select the reason that, after the blank is measured, the cuvette must be placed in the spectrophotometer in the same orientation each time that it is used. o the spectrophotometer will break if the cuvette position is changed during the experiment. o the transmittance of the liquid must be measured in the same place each time. o the cuvette will only fit into the spectrophotometer in one orientation. o the transmittance of the cuvette must be measured in the same place each time.

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
