A particle moving in one dimension (the x-axis) is described by the wave function

?(x)={Ae?bx, Aebx, forx?0forx<0

where b = 2.00 m?1, A> 0, and the +x-axis points toward the right.

Part A

Determine A so that the wave function is normalized.

Part B

Sketch the graph of the wave function. Plot the points for increments of ?x = 0.2 m.

Part C

Find the probability of finding this particle in each of the following regions: within 60.0 cm of the origin.

Part D

Find the probability of finding this particle in each of the following regions: on the left side of the origin (can you first guess the answer by looking at the graph of the wave function?).

Part E

Find the probability of finding this particle in each of the following regions: between x = 0.600 m and x = 1.15 m .

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force

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.
