Use the HR diagram below to answer the question. Labeled HR diagram. The main sequence slopes from the upper-left of the diagram, which is blue, to the bottom-left of the diagram, which is red-orange. White dwarfs cluster at the bottom of the diagram, in the light blue section. Red giants cluster in the middle of the diagram, in the orange-red section. Red supergiants cluster at the top of the diagram, in the orange-red section. What can be concluded about the initial mass of a blue main sequence star compared to a red main sequence star? Blue main sequence stars had a greater initial mass. Red main sequence stars had a greater initial mass. Blue main sequence stars have the same initial mass as red main sequence stars. Initial mass comparisons cannot be made between blue and red main sequence stars.

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)

This is a form of winter precipitation. it is frozen precipitation falling as ice pellets. snowflakes melt into raindrops as they pass through a thin layer of warmer air. the raindrops then refreeze into particles of ice when they fall into a layer of sub-freezing air near the surface of the earth. this precipitation is called a) hail. b) rain. c) sleet. d) snow.
