A student pulls an object (126kg) along a rough flat surface by a massless string. The tension force exerted by the string on the object is 148.0N, as the pot is pulled forward 15.0m at a constant velocity of (0.5 m/s)i. 1. Calculate work done by tension force on object over this distance
2. If student speeds up increasing the tension force in the string over a distance of x=0 to 6.0m. Find work done by tension force

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.
