A BCC iron structure is to be manufactured that will allow no more than 50 g of hydrogen to be lost per year through each square centimeter of the iron at 400 oC. If the concentration of hydrogen at one surface is 0.05 H atom per unit cell and is 0.001 H atom per unit cell at the second surface, determine the minimum thickness of the iron. (50 points) Given : DH in BCC Fe at 400 oC is 8.129 x 10-5 cm2/sec; Atomic weight of H, MH = 1.008 g/mol, The lattice parameter of BCC Fe is, a = 0.286 nm. Hint: Express the concentrations in units of atoms/cm3.

Assume the random variable $X$ is normally distributed with mean $\mu = 50$ and standard deviation $\sigma = 7$. Compute the probability. Be sure to draw a normal curve with the area corresponding to the probability shaded. $P(34 < X < 64)$ Click the icon to view a table of areas under the normal curve. Which of the following normal curves corresponds to $P(34 < X < 64)$? $P(34 < X < 64) = \boxed{}$ (Round to four decimal places as needed.)

I want to realize a transmission hologram for a college project. One of the requirements is to create a project and then mesure something with it. Do you have any suggestion on what i could mesure and how to mesure it? (It can't be something like find the wavelenght of the laser beam)

Q5- The simple weighing system shown above consists of: Two identical linear springs with a stiffness constant K=96[(N)/(cm)] A rack with a 4 [teeth/cm] pitch. A pinion gear having 15 [teeth]. A display dial having Δθ=288[deg], with the dial pointer directly connected to the pinion gear. Hence, calculate: a) The maximum measurable force in units of [N]? b) The maximum measurable mass in units of [kg]? c) The sensitivity of the system in units of [deg/kg]? Note: Let the gravitational acceleration constant g=10[m/s^2]
