He total length of the strand is l = 11.0 m, the mass of the strand is m = 6.00 g, the mass of the hanging object is m = 6.00 kg, and the pulley is a fixed a distance d = 8.00 m from the wall. you pluck the strand between the wall and the pulley and it starts to vibrate. what is the fundamental frequency (in hz) of its vibration?

Ms. hidalgo opens the door to her classroom. her classroom is 60 degrees and the air outside is 80. predict what will happen using your knowledge of how heat flows.

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
