Awave traveling in water has a frequency of 250 hz and a wavelength of 6.0 n. what is the speed of the wave?

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius 푅=0.381meters and mass 푀=3.1푘푔. initially 푚"is on the ground and 푚#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of 푚#just before it strikes the ground. assume the pulley bearing is frictionless.

A12-g wad of sticky clay is hurled horizontally at a 100-g wooden block initially at rest on a horizontal surface. the clay sticks to the block. after impact, the block slides 7.5 m before coming to rest. if the coefficient of friction between the block and the surface is 0.65, what was the speed of the clay immediately before the impact?

Use a graphic approach to systematically represent the root causes of a problem, the relationships between different causes, and sometimes a prioritization of which causes are most important. a. cause analysis approaches b. force-field analyses c. cause-and-effect diagrams d. root-cause diagrams
