The center of the moon is 0.0026 au (3.890 x 10^8 m) from the center of the earth and has a relative mass of 0.0123. locate the cm of the earth-moon system with respect to the center of the earth. with respect to the center of the moon. find the ratio of orbital velocities of the earth and moon about the cm of the system. if the orbital velocity of the moon is 1012 m/s, what is the approximate orbital velocity of the earth about the cm of the earth-moon system?

9. an object is moved from the outdoors, which is at a temperature of 100 ºf, to a room at a temperature of 70 º f. what happens to the object when it’s placed in the room with a lower temperature? the object gives off more energy than it absorbs until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same. the object gives off the same amount of energy as it absorbs until it reaches a new lower thermal equilibrium where the amount of energy given off is greater than the amount of energy it absorbs. the object gives off more energy than it absorbs until it reaches a new higher thermal equilibrium where the amount of energy absorbed and given off is the same. the object absorbs more energy than it gives off until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same.
