• Question 1 A population of values has an unknown distribution with $mu = 210.7$ and $sigma = 34.2$. You intend to draw a random sample of size $n = 80$. What is the mean of the distribution of sample means? $mu_{ar{x}} = $ (Please enter an exact answer.) What is the standard deviation of the distribution of sample means? $sigma_{ar{x}} = $ (Please report your answer accurate to 2 decimal places.)

1. Write an introduction section (see the Laboratory Techniques Manual p. 6) for this experiment. In the introduction section give background information on how salicylic is prepared industrially and how you are synthesizing it in the lab. In addition, outline the overall base-promoted saponification of an ester and then draw and describe the mechanism using the curved-arrow formalism (include lone pair electrons) to give the corresponding carboxylate ion and an alcohol via a nucleophilic acyl substitution reaction.

(5.8) Consider a CMOS process for which Lin=0.25 μm, t=6 nm, μ=460 cm/Vs, and V=0.5 V. a) Find C and k. b) For an NMOS transistor with W/L=20 μm/0.25 μm, calculate the values of Vov, Vds, and Vgsmin needed to operate the transistor in the saturation region with a dc current I=0.5 mA. c) For the device in b, find the values of Vov and Vgs required to cause the device to operate as a 100 Ω resistor for very small Vds. (5.9) A p-channel MOSFET with a threshold voltage Vth=-0.7 V has its source connected to ground. a) What should the gate voltage be for the device to operate with an overdrive voltage of Vov=0.4 V? b) With the gate voltage as in a, what is the highest voltage allowed at the drain while the device operates in the saturation region? c) If the drain current obtained in b is 0.5 mA, what would the current be for Vds=-20 mV and for Vds=-2 V? (5.15) An NMOS transistor having Vth=0.8 V is operated in the triode region with Vds small. With Vgs=1.2 V, it is found to have a resistance rds of 1 kΩ. What value of Vgs is required to obtain rds=200 Ω? Find the corresponding resistance values obtained with a device having twice the value of W.

Please answer these two questions: 1. A glycerin with a viscosity of 25 flows through a pipe with a diameter of 200mm. Is the flow laminar or turbulent? Given that the density of the glycerine is 1258kg/m^3. 2. An engineer claims that the flow of SAE 30W oil, at 20°C, through a smooth pipe with a diameter of 5cm and a flow rate of 0.0318 m^3/s is laminar. Do you agree?
