1) [A] Determine the factor of safety of the assumed failure surface in the embankment shown in the figure using simplified method of slices (the figure is not drawn to a scale). The water table is located 3m below the embankment surface level, the surface surcharge load is 12 KPa. Soil properties are: Foundation sand: Unit weight above water 18.87 KN/m Saturated unit weight below water 19.24 KN/m Angle of internal friction 289 Effective angle of internal friction 31 Clay: Saturated unit weight 15.72 KN/m Undrained shear strength 12 KPa The angle of internal friction 0 Embankment silty sand Unit weight above water 19.17 KN/m Saturated unit weight below water 19.64 KN/m The angle of internal friction 22 Effective angle of internal friction 26 Cohesion 16 KPa Effective cohesion 10 KPa Deep Sand & Gravel Unit weight above water 19.87 KN/m Saturated unit weight below water 20.24 KN/m The angle of internal friction 34 Effective angle of internal friction 36 Question 1. Predict the structure of the amino acid produced by using the starting material the following and outline the synthesis steps structure of amino acid with appropriate reagents (mechanism is not required) 0 Br CHCHCH_CCOOH I Here is a simplified version of the game "Win an additional mark if U can!".There are two players.Each player names an integer between 1 and 4.The player who names the integer closest to two thirds of the average integer gets a reward of 10, theother players get nothing.If there is a tie (i.e., choosing the same number), each player gets reward of 5.(a) Represent this game in Normal Form. (b) Answer the following questions When player 2 chooses 4, what are the best responses for player 1?When player 1 chooses 3, what are the best responses for player 2?When player 2 chooses 2, what are the best responses for player 1?When player 1 chooses 1, what are the best responses for player 2?For player 1, is the strategy of choosing 4 strictly or very weakly dominated by another strategy? Ifso, which ones?For player 2, is the strategy of choosing 1 strictly or very weakly dominated by another strategy? Ifso, which ones?(c) What is the Nash equilibrium of this game? Find this out by applying the concept of dominated strategies to rule out a succession of inferior strategiesuntil only one choice remains. e Complete the steps below using pseudocode or C++ code. // copy/paste and provide answer below each comment // Declare a string variable with the name message and initialize it with "Hello world!" // Display message and its length to the screen // Count number of non-alpha characters (not a letter i n alphabet) in message // and store result in an integer variable count; // feel free to declare additional variables as needed I am being asked to write a 10 pg research proposal in APA for my biological psychology class.

Q Question 8 Consider the following redox reaction which was conducted under acidic medium to answer this question. M2+ + XO3 MO4 4 x3+ A 0.166 M MC1 (MM = 124.8) aqueous solution was placed in a buret and titrated against a 3.35 g sample of 81.1% pure NaXO3 (MM = 279.7) that had been dissolved in an appropriate amount of acid until the redox indicator changed color. Given this information, how many mL of titrant were necessary to completely react with the titrand? Use 3 significant figures to report your answer. A Click Submit to complete this assessment.
