Skylar wants to improve her fitness level for a chance to be on the rowing team. She has been rowing 2–3 times per week at 9 m. p.h. at her local gym for 30 minutes, with her heart rate increasing to between 155–170 beats per minute. She is using the frequency principle to improve her fitness level when she increases her: days rowing to 4–5 per week heart rate to 165–180 beats per minute rowing speed to 11–12 m. p.h. time rowing to 40–45 minutes per session

What statements accurately describe atoms

For problems 1-3, consider a simple dc brush motor with a permanent magnet stator. with an an consider a simple dc brush motor with a permanent magnet ae supply voltage of 100 v, the no-load speed of the motor is 1000 rpm. this motor can provide a torque of 1.9 n-m at 800 rpm drawing a current of 2 a current are both zero at no load.) 1. with an armature supply voltage of 100 v, the motor is operated at 900 rpm. what is the motor torque? what is the mechanical power delivered by the motor? what is the current draw? what is the electrical power input? what is the energy efficiency of the motor? with an armature supply voltage of 100 v, the motor is operated at 1100 rpm (where it acts as a generator). what torque input is required? what mechanical power is required what current is generated? what is the electrical power generated? what is the energy efficiency of the motor acting as a generator? 2. with an armature supply voltage raised to 120 v, the motor is operated at 1000 rpm. what is the no-load speed? what is the motor torque? what is the mechanical power delivered by the motor? what is the current draw? what is the electrical power input what is the energy efficiency of the motor? 3.

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.
