Plsss pl plsss Two carts weighing 3kg and 2.5kg move on a smooth horizontal surface with speeds of 2m / s and 3m / s, the directions of which are shown in fig. After the collision the two carts move together as a single body. Find the magnitude of the speed and what is the direction of movement of the two carts after hitting them.​

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.
