N outer space two identical spheres are connected by a taut steel cable, and the whole apparatus rotates about its center. The mass of each sphere is 42 kg. The distance between centers of the spheres is 4.5 m. At a particular instant the velocity of one of the spheres is <0, 11.0, 0> m/s and the velocity of the other sphere is <0, -11.0, 0> m/s. What is the tension in the cable

Alow cost, low earth orbit (leo) satellite is to be fabricated at a university, for subsequent launch by rocket. what are the constraints and objectives for selection of a material suitable for the satellite bus (i. e. the structure)? explain each in brief. (15 marks) b)suggest sources of data which could support the selection of materials for applications in space. (5 marks) c) set weights for the objectives listed in (2a) using the digital logic method. (5 marks)
