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

The land along the great lakes' coasts is known as "the fruit belt" because of the year-round ideal conditions for fruit farming. how are the coastal air temperatures affected by the great lakes, creating profitable conditions for fruit farmers? a) during winter, the great lakes act as a heat source, to regulate extreme temperatures in the surrounding areas. b) hills and mountains surrounding the great lakes area force warm air downward toward the lake, making the coastal areas warmer. c) the elevation of the great lakes is higher than the surrounding areas, causing air to heat and cool slowly, without damaging crops. d) dry regions surrounding the great lakes cause warm air masses to move quickly across the lakes, resulting in more stable temperatures.
