(a)
Interpretation:
Whether
Concept introduction:
Semiconductors are devices that have conductivity intermediate between conductors and insulators and their conductivity gets enhances when doped.
Doped semiconductors are used in commercial electronic devices as diodes, transistors, LEDs, photovoltaic cells. They all differ in their functions that are as follows:
- Diodes convert alternating current to direct current.
- Photovoltaic cells convert sunlight to electricity.
- LEDs act as a light source.
- Transistors amplify an electrical signal in an integrated circuit.
(b)
Interpretation:
The LED that emits red and the LED that emits UV light should be determined.

- CS2(g) → CS(g) + S(g) The rate law is Rate = k [CS2] where k = 1.6 × 10-6 s−1. S Calculate the half-life.arrow_forwardThe following is a first order reaction where the rate constant, k, is 6.29 x 10-3 min-*** What is the half-life? C2H4 C2H2 + H2arrow_forwardControl Chart Drawing Assignment The table below provides the number of alignment errors observed during the final inspection of a certain model of airplane. Calculate the central, upper, and lower control limits for the c-chart and draw the chart precisely on the graph sheet provided (based on 3-sigma limits). Your chart should include a line for each of the control limits (UCL, CL, and LCL) and the points for each observation. Number the x-axis 1 through 25 and evenly space the numbering for the y-axis. Connect the points by drawing a line as well. Label each line drawn.
