The electric-vehicle manufacturing company Tesla estimates that a driver who commutes 50 miles per day in a Model S will require a nightly charge time ofaround 1 hour and 45 minutes (105 minutes) to recharge the vehicle's battery (Tesla company website). Assume that the actual recharging time required isuniformly distributed between 90 and 120 minutes.a. Give a mathematical expression for the probability density function of battery recharging time for this scenario.A. f(x) =for 90

Given information X ~ Uniform (α = 90, β = 120) Uniform distribution Hence, Option a is correct

OPTOELECTRONIC DEVICES. : A relay is controlled by a photo-conductive cell which has a resistance of 1kilohm when illuminated and 100 kilo ohm when in the dark. The relay is supplied with 10 mA from a 30-V supply when cell is illuminated and is required to be re-energized when the cell is in the dark. Sketch a suitable circuit and calculate the required series resistance and value of dark current.

The construction of PV solar cells uses a number of critical elements. One is indium an ingredient of the transparent conducting coating on the surface of the cell. The average material intensity for indium in solar cells is approximately 0.05 kg/kWnom. Calculate the quantity of indium that would be required for a project that would provide PV solar power with capacity factor of 0.25, sufficient to meet one third of the present needs of the US, population 301 million, each using an average of 10.2 kW. The current world production of Indium is 600 tones per year. If the solar project were to be implemented over a 5 year time span, is it true that the supply of indium be adequate?
Please provide Handwritten answer. 9. After following all the steps in the photolithography, a student found that all the photoresist (the exposed and unexposed photoresist) on the silicon wafer was washed away during the development step. This is due to... * A) the student used longer exposure time during alignment and exposure step B) the student used slower spin speed during spin coating producing thicker photoresists C) the student used longer development time during the development step D) the student used lower temperature and shorter baking time during the pre bake step E) the student misaligned the mask with the wafer during the alignment step 10. After photolithography process the wafer will go to the either etching process or doping process such as ion implantation and diffusion. * True or False
