Which solution is correct the question is same Practice Problem #3 For the retaining wall shown in Figure 13.19a, determine the force per unit length of the wall for Rankine's active state. Also find the location of the resultant. y = 16 kN/m = 30 d' = 0 Groundwater table Y = 18 kNm = 35° 0% = 7zK, -20'/K. 20 Ø 1:32 Answer 1 of 1 D + Ramkine ra' active Pressure y z k-2 - SKA Po or...
help with calculating the “initial [SCN^—]” M and the Equilibrium [Fe(SCN^2+)] M. i have one. just not sure how to set up the equation to find the inital [SCN^-] . not sure if im calculating it correctly. Data Manipulation and Calculations Calibration Solutions Data 1. Calculate the "Initial [SCN']" molarities for the solutions using the dilution equation CiVI=C2V2 2. Use the net ionic equation for the reaction, the ratio of [Fe3 [SCN'] used, and your knowledge of Le Châtelier's Principle...
please i need help with this Question 4 10 pts Brian is on Mars and decides to dump his physics textbook into this never before seen hydrocarbon lake. The atmospheric pressure in Mars is 1/4 that of Earth's and the gravitational acceleration is 3m/s^2. The hydrocarbon liquid has a density of 1300 kg/m^3. If the book is experiencing a force of 426 N underneath the lake, how deep is the book inside the lake? The book has a surface area...

i need help in problem 3.6 which is the first picture. the other 2 pictures are the equations that i need. opened read only to prevent modification incompressibly, which because of the large strains cannot be accoun for via v = ). If the original length is L and the current length is /, volu conservation requires LA,=IA - A=A.(L/I) assuming uniform str and strain. Hence, 0x = A 4 = AS where A=1/L is a stretch ratio and is...
