The input voltage to a DC motor is 12 V. The motor rotates at 2,200 rev>min at no load (maximum speed). Stall torque is 0.44 N-m, and the corresponding current is 9.0 A. Operating at 1,600 rev>min, the torque is 0.12 N-m, and the current is 2.7 A. Based on these values, determine: a. the torque constant
b. voltage constant
c. armature resistance of the motor.
d. how much current does the motor draw operating at 1,600 rev/min

Using a pedometer, you walk 3000 steps in 20 minutes, so your speed is 150 steps/min. each of your steps is 0.7 m long. what is your speed? 150 steps/min=/s=/h

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?

Asubject in a clinical research trial experiences a serious, unanticipated adverse drug experience. how should the investigator proceed, with respect to the irb, after the discovery of the adverse event occurrence? a. do not report the adverse drug experience to the irb since it is a common adverse experience. b. report the adverse drug experience to the irb only if there are several other occurrences. c. report the adverse drug experience as part of the continuing review report. d. report the adverse drug experience in a timely manner, in keeping with the irb's policies and procedures, using the forms or the mechanism provided by the irb.
