Your motor has a stall torque of 6.25 kg-cm and a no load speed of 1250 rpm. your operating point for your application is to spin with a speed of 400 rpm with a torque of approximately 1.75 kg-cm. you do not have a gearbox or any other way of introducing mechanical advantage. what should your pwm duty cycle be for this motor and operating point?

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

force tends to be low and long diustance masses are high

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
