Two groups were tasked to measure the mass of the metal objects given by their teacher. Rachel’s group has the following data for 3 trials: 97 g, 98 g, and 99 g. Meanwhile, Ashley’s group has 99.5 g, 100.1 g, and 100.5 g. If the accepted value for the metal’s mass is 100 g, how will you describe the data of each group in terms of precision and accuracy?

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
