A spherical wood with a diameter of 6cm is immersed in a container of liquids with the oil filled to a height of 6cm and the mercury is filled to a height 8cm above the oil. If the diameter of the wood is at the interface between mercury and oil, calculate, (a) The gauge pressure at the upper surface of the block? (b) The gauge pressure at the lower surface of the block?

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
