Using those numbers, answer the following questions: a) What is the mass of a single gold atom in kg? b) Assume that gold atoms sit in a perfect cubic crystal structure. Estimate the distance between two gold atoms in meters. c) If we have a gold cube of 6 cm on each side, how many atoms can we fit along the edge of each side of the cube? d) What would be the mass, in kilograms, of the gold cube we discussed in part (c) (measuring 6 cm on each side)?Please answer question and just send me the paper solutions asap dont type the answer question and just ex2 answer all the parts please faster and use the equation from picture please asapNeed a good explanation and step by step solution for this problem, not just copied out of the solutions manual.
- Hello, please I really need help with part D and part E I really don't understand understand those two problems I have done all of the other parts I just need help with that one, please I need help with part D and part E and can you label themConsider the following examples and try to imagine the possible scenario that may happen. To do so, fill in the provided outline after each example, and then, complete the general statement belowYou are handed a bat that is 6 times as dense on one side as it is on the other side, and 3 times as dense in the middle as it is on the least dense side. Density varies quadratically. The mass of the bat is M and the length is L. Write your answers only in terms of these constants. > Place the rod somewhere along the x-axis. What is the linear mass density function A(x) of the rod? Hint: To eliminate a constant, note that integral dm=M
- The given graph shows stopping distances for trucks at various speeds on dry roads and on wet roads. Use this information to solve, a. Use the statistical menu of your graphing utility and the quadratic regression program to obtain the quadratic function that models a truck’s stopping distance, f(x), in feet, on wet pavement traveling at x miles per hour. Round the x-coefficient and the constant term to one decimal place. b. Use the function from part (a) to determine speeds on wet pavement requiring stopping distances that exceed 446 feet.Please be clear and answer the question with all the formulas used to resolve the problem. Thank you ?Please show all the steps and equations you use and their units.
