cos( x 2 )cos( y 2 )) hat j is conservative and obtain the potential function. Evaluate the work done by vec F in moving a particle along the curve C which is the portion of the circle centered at origin with radius 2 in the first quadrant with counter clockwise orientation, without using line integrals.

ions, Cartesian coordinates, graphs, kinematics. Trigonometric functions Exponential and logarithmic functions Limits and differentiation Algebra, vector and matrices Combinatorics and Probability This task is divided in 3 stages. each stage will have its own milestone and will be released upon completion and review. Please just bid if you are available for all the tasks, check carefully the times. Complete a questionary with the math questions, approx. 7 pages every answer should be complete and extensive and fully explained in order to be fully understood the process. Approx. time 2 to 2.5 hours. Task 2 will take place on Monday, September 6, 2021 at: 1:00pm / 13:00 Coordinated Universal Time (UTC) This task will include a similar questionary with A B OR C Answers, approx time 1.5 hours to 2 hours, This questions will be provided one by one and requires that we connect by chat live. Task 3 will take place on Monday, September 6, 2021 at: 1:00pm / 13:00 Coordinated Universal Time (UTC) after task2 Upon completion of task 2 a document similar to task 1 will be provided in pdf, this one need to be completed within 4 hours after provided approx. 7 pages every answer should be complete and extensive and fully explained in order to be fully understood the process. For now I will provide task 1 document.

stions: Based on the energies you found in c and d, which of these complexes has the largest predicted splitting between the t2g orbitals and the eg orbital. Remember--not every element has occupied d-orbitals. How is that going to impact your next answers? Which one would absorb the longer wavelength of light? Explain why. Transition metal complexes are often vibrantly colored due to the splitting of the d-orbitals caused by the ligands. Based on your results would you expect that both of these complexes have any significant color? Explain.

formula online to help.. It should be a simple straightforward problem but i just can not for the life of me figure it out. are you able to provide me with a formula or point me in the right direction? The problem is: Solution A has a 50% concentration Solution B has a 100% concentration Solution C has a 5% concentration you have 5L of each solution to utilize as well as unlimited quantities of water to dilute solution concentrations if needed. Part A Make a final solution of 100ml with solution concentrations of Solution A 15%, solution C 5% and solution C 80%. how much of each solution will you need to make your final 100ml solution? Part B using the above solutions how many 100ml final solutions can you produce with the 5L volumes? No matter how I work it i can't make the solution to the correct concentrations. Thank you for your help. John

bundance of isotope I is (1.94x10^1)%, what would be the calculated atomic mass (in amu)? 2) A hypothetical element exists as two isotopes: I = 78.00 amu and II = 84.00 amu. If the atomic mass of this element is found to be 80.33 amu, which isotope must be more abundant? 3) If the hypothetical polyatomic ion ThOM2- is called "thomite", what would be the formula and name of the acid formed by this ion? 4) How many atoms of hydrogen are there in a sample of (4.00x10^2) grams of NH3(g)? 5) How many O (oxygen) atoms are there in (6.40x10^2) grams of H3PO4? 6) How many moles of fluorine atoms are there in (5.80x10^2) grams of SF4? 7) When 3.50 g of titanium (Ti) reacts with oxygen, the resulting oxide compound weighs 5.84 g. What is the empirical formula of this oxide? 8) How many moles of molecules are there in (6.70x10^2) grams of CH4? 9) A chemical is found to be 80.0% C and the rest is H. If the molar mass of this chemical is known to be 90.2 g/mol, what is the molecular formula?

and how to solve: “A history lecture hall class has 15 students. There is a 15% absentee rate per class meeting. Find the probability that exactly one student will be absent from class.” I already know that: n = 15 p = 15% q = 1 - 15 = 1 - 0.15 = 0.85 ...and then you do: p (x = 1) = C 15 & 1 and then... (0.15)^1 (0.85)^14 Please help me understand the rest. Thank you!

is Imagine that in the voting for a certain​ award, 7 points are awarded for first​ place, 4 points for​ second, 3 points for​ third, 2 points for​ fourth, and 1 point for fifth. Suppose there were five candidates​ (A, B,​ C, D, and​ E) and 47 voters. When the points were​ tallied, A had 155 ​points, B had 173 ​points, C had 170 ​points, and D had 154 points. Find how many points E had and give the ranking of the candidates.​ (Hint: Each of the 47 ballots hands out a fixed number of points. Figure out how​ many, and take it from​ there.)
