A spherical buoy has a diameter of 1.5 m, weighs 8.50 KN, and is anchored to the sea floor with a cable as is shown in Figure 1. Although the buoy normally floats on the surface, at certain times the water depth increases so that the buoy is completely immersed as illustrated. For this condition what is the tension of the cable? Given, density of the sea water = 1025 kg/m3.
what is the velocity of the cart when the bullet becomes embedded int he terget? during the firing, the man remains at the same position on the cart. neglect rolling resistance of the cart.
Two kilograms of Refrigerant134a, initially at 2 bar and occupying a volume of 0.12 m3, undergoes a process at constant pressure until the volume has doubled. Kinetic and potential energy effects are negligible. Determine the work and heat transfe..
