Infinite and finite potential energy well First consider an infinite one dimensional PE well of width 1 nm. Calculate the energies of the first three levels. Consider a finite PE well with the same width (1 nm). The height of the barrier is 2.0 eV. There are only three energy levels E1 0.23 eV. E2- 0.89 eV, and Es 1.81 eV. Are the finite PE well levels higher or lower than the corresponding infinite well levels? Find the electron penetration depth into the barrier for each of the three energy levels. What is your conclusions?

Machinery that is a key part of the process and without which the plant or process cannot function is classifed as: (clo4) a)-critical machinery b)-essential machinery c)-general purpose machinery d)-none of the specified options.

In general, how do thermosetting plastics compare to thermoplastics in mechanical and physical properties?

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
