An electric pole shown in the figure below supports a power line that passes through it. A cable tied to the pole at B passes through a hole in the struct at C and is then tied to the ground at B. There is no friction between the struct and cable. What is the force exerted by the cable onto the pole at B, if the tension in the cable is 47lb.

c)as speed changes, wavelength and frequency change.

everything changes!

radiation

explanation:

heat is transmitted by radiation

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
