A rocket is used to place a synchronous satellite in orbit about the earth. What is the speed of the satellite in orbit? O 3070 m/s O 4070 m/s O 2070 m/sA satellite circles the earth in an orbit whose radius is 4.72 times the earth's radius. The earth's mass is 5.98 x 1024 kg, and its radius is 6.38 x 105 m. What is the period of the satellite?The second hand and the minute hand on one type of clock are the same length. Find the ratio (ac, second/ac,minute) of the centripetal accelerations of the tips of the second hand and the minute hand.A centrifuge is a device in which a small container of material is rotated at a high speed on a circular path. Such a device is used in medical laboratories, for instance, to cause the more dense red blood cells to settle through the less dense blood serum and collect at the bottom ofthe container. Suppose the centripetal acceleration of the sample is 5.36 x 103 times as large as the acceleration due to gravity. How many revolutions per minute is the sample making, if it is located at a radius of 7.92 cm from the axis of rotation? To create artificial gravity, the space station shown in the drawing is rotating at a rate of 1.20 rpm. The radii of the cylindrically shaped chambers have the ratio rA/re = 3.00. Each chamber A simulates an acceleration due to gravity of 5.10 m/s2. Find values for (a) rA, (b) rB. and (c) the acceleration due to gravity that is simulated in chamber B.
