URGENT PLS HELP The radius of one of the planets in the solar system is r = 4.5 x 1012 m and its orbital period is T = 165
years. What is the magnitude of the orbital velocity of this planet around the sun, assuming a circular
orbit?
(1 point)
O2.17 x 103 m/s
O 8.24 x 104 m/s
O 6.33 X 102 m/s
O 5.43 x 103 m/s

The mini-refrigerator fire was most likely caused by what type of wiring?

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.

What organization and environment is described above?
