Question 2 (1 point) ✓ Saved (3.03.b_Q2) NOTE: The same story problem is used for questions 1 - 5: In a
piston/cyclinder gas container, the piston starts with a inside gas volume of 3.0 cc
and a pressure of 0.8 atmosphere at room temp. The piston is pushed into the
cylinder, reducing the volume to 1.0 cc. The piston/cylinder is left to equilibrate
back to room temp before measuring the final pressure.
Which gas law formula should be used to solve this opportunity?
constant volume, initial P/T = final P/T
constant temperature, initial PV = final PV
constant pressure, initial V/T = final V/T
density = mass/volume

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.

What are similarities and differences of reflection, refraction, diffraction and absorption?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
