Consider the image below depicting an ideal gas contained within a 4.5 L 4.5 L cylinder under a constant force. If 3.0 × 10 − 3 moles 3.0×10−3 moles of gas are occupying the cylinder and the temperature of the gas is 350 K 350 K, determine the mass of the weight on the cylinder. Assume the top of the cylinder has an area of 1.0 m 2 1.0 m2, and atmospheric pressure can be ignored.

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
