Using the principles to be developed in chapter 3 on equilibrium, one can determine that the tension in cable ab is 143.4 n. determine the moment about the x-axis of this tension force acting on point a. compare your result with the moment of the weight w of the 15-kg uniform plate about the x-axis. what is the moment of the tension force acting at a about line ob?

Ahorizontal wire is tied to supports at each end and vibrates in its second-overtone standing wave. the tension in the wire is 5.00 n, and the node-to-node distance in the standing wave is 6.28 cm. (a) what is the length of the wire? (b) a point at an anti- node of the standing wave on the wire travels from its maximum upward displacement to its maximum downward displacement in 8.40 ms. what is the wire's mass?

Which boundary is associated with the building of the himalaya mountains? convergent transform divergent hot spot
