Two boxes, A and B, are connected by a lightweight cord and are resting on a smooth table. The boxes have masses of 120 kg and 100 kg a horizontal force of 400 N is applied to the 100 kg box. Find the tension in the cord connecting the boxes ?​

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
