A12-pole, brushless, dc motor has a no-load speed of 5000rpm and a stall torque of 50 in-oz when operating at rated voltage of 60v. testing shows that no-load speed and stall torque vary linearly with applied voltage. also, with a constant applied voltage the speed decreases linearly as delivered torque increases. calculate the following: torque that the motor delivers at 2000 rpm when operated at rated voltage. t a) b) fundamental frequency of the applied voltage waveform at this operating condition ) stall orque and no-load speed when operated at 40v. d) motor speed when operated at 40 volts and delivering 15 in-oz of torque n- e) the voltage that should be applied to the motor to achieve a speed of 2000 rpm when delivering 5 in-oz of torque.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
