A baseball has a mass of 140 grams and a softball has a mass of 280 grams. In which of the following situations would they both have the same momentum?

A. The baseball and softball are thrown at 33 m/s in the same direction.
B. The baseball and softball are thrown at 33 m/s in opposite directions.
C. The baseball is thrown at 25 m/s and the softball is thrown at 50 m/s.
D. The baseball is thrown at 50 m/s and the softball is thrown at 25 m/s.

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
