Two glass bulbs each having a volume of exactly 1L are connected by a valve. The left bulb contains a sample of nitrogen gas at a pressure of 101.325 kPa (kiloPascal), the right bulb has been evacuated (all the gas has been removed) and the pressure in the right bulb is 0 kPa. A) The gas will expand into the empty bulb. Expansion of the gas will increase the gas pressure and increase the gas temperature.

B) The volume available for the gas will double Doubling the volume will cause the pressure and temperature to decrease .

C) The gas will expand into the empty bulb Expansion of the gas will increase the gas pressure and decrease the gas temperature

D) The volume available for the gas will double Doubling the volume will increases the amount of gas to keep the pressure constant

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.

3. a lunar exploration vehicle was created by a research team. it weighs 3,000 kg on the earth. it needs an acceleration of 10 m/s2 on the moon. in order to have the same acceleration, what will be the net force acting on the vehicle on the earth?
