The sun radiates energy at the rate 3.8 × 1026 W. The source of this energy is fusion, a nuclear reaction in which mass is transformed into energy. The mass of the sun is 2.0 × 1030 kg. Part A How much mass does the sun lose each year? Express your answer using two significant figures. AM = 1.3x1017 kg Submit Previous Answers Part B Review | Constants | Periodic Table Correct Correct answer is shown. Your answer 1.32-1017 = 1.32x1017 kg was either rounded differently or used a different number of significant figures than required for this part. What percentage is this of the sun's total mass?

I Review Constants Periodic Table (Figure 1) In an old-fashioned amusement park ride, passengers stand inside a 3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their backs against the wall.. The cylinder begins to rotate about a vertical axis. Then the floor on which the passengers are standing suddenly drops away! If all goes well, the passengers will "stick" to the wall and not slide. Clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70. Part A What is the minimum rotational frequency, in rpm, for which the ride is safe? Express your answer in revolutions per minute. Figure 1 of 1 • View Available Hint(s) f = rpm Submit
