Suppose the production cost is R293 250 , computing components cost is R1035 , labour costs is R4140 and the savings on reusable material is R1725, what is the number of devices produced?
Which diode approximation
a. treats a reverse-biased diode like an open switch with
zero current?
b. includes the high leakage resistance when the diode
is reverse-biased?
How many grams of Cu(OH)2 will precipitate when excess Ba(OH)2 solution is added to 77.0 mL of 0.678 M Cu(NO3)2 solution?
Company ALPHA wants to devise an Employee Presence Monitoring System (EPMS) to monitor effective working time of an employee. Apart from details such as Emp_ID, Age, address, contact number etc., each employee will have a special counter. First time an employee enters into the office, the counter is set to 1. From then onwards, each time an employee leaves the office premises for tea break or lunch break, and enters back this id is incremented. You can figure out that when this id is odd on a day, he is in the office premises and even when he is out. EPMS also records the number of breaks and total duration of the break in a dayThe organization uses this data to perform the following analytics:
How many employees came today?
Did a particular employee come today?
How often did an employee enter into the office?
Which employee moves out of office most number of times?
Name of the employees who are all out for a particular time period
Who all came within a range of IDs, and how often they entered?
A 3000 kg elevator rises from rest in the basement to the floor. A distance of 25m . As it passes the fourth floor it's speed is 3 m/s . There's a constant frictional force of 500N. Calculate the work by the lifting mechanism?
Calculate the concentration of C6H5NH2, H3O+, and OH− in a 0.230 M C6H5NH3Cl solution. (Kb(C6H5NH2)=3.9×10^−10
Calculate the concentration of C6H5NH3+ and Cl− in a 0.230 M C6H5NH3Cl solution.
The vendor provided 95% pure antimony trioxide [Sb2O3] powder chemical. Molar mass of elements (Sb: 121.8 g/mol; O: 16 g/mol). Solve the following problems to get accurate initial Sb(III) concentration for lab-scale experiments. Hint: The Sb(III) solution needs to be prepared in 1 M HCl solution.
i.How much chemical in mg/L will be required for preparation of 1 g/L Sb(III) stock solution?
ii.What will be the dilution factor to prepare 10 mg/L Sb(III) solution?
Write a function called propagateUncertainty() that accepts as input two variables in the format x = [x_best,dx] and y = [y_best,dy]. Have your function calculate the sum q = x + y as well as the corresponding max uncertainty dq = dx + dy and return an answer in the same format of the inputs (i.e., q = [q_best,dq]).
If either of the inputs does not have two entries, your function should return the string "Fail" and print the statement "Array length must be equal to two with the format x = [x_best,dx]."
If either of the inputs contains non-numeric entries (i.e., type(entry) is not equal to "int" or "float"), your function should return the string "Fail" and print the statement "Non-numeric entry!"
