If you can’t find homework answers by yourself, turn to our experts to get professional response in any academic field. Even being good at all subjects, you may also be trapped for hours with one of those tricky questions. So, when there are some points needed to be explained, we offer you our help. No matter whether you have questions in in math, physics, programming, economics, chemistry, biology or English, post them here and find a well-formulated answer from an expert within a short time. You may be surprised, but we help with homework answers for free if they require brief explanation. After the answer is found, it is published on the Homework Answers page so that everybody can see it and get similar help. However, if your question is over certain volume and complexity, it should be submitted as the task for evaluation.
Use filters to display the questions to a particular subject or section. By entering your e-mail in the “Search” box you can browse the questions posted exclusively by you. Do not worry if you cannot find your question in the list right after it has been submitted; every question is being checked by a moderator and appears published only after it is accepted.

Polly Pipe is focused in placing aquariums at business customers. Customers can request several installations, but each installation is tailor-made for a specific customer. Facilities are classified by type. One or more employees are assigned to each facility. Because these facilities are often very large, they can include carpenters and masons as well as water installers. The facilities use equipment such as aquariums, air pumps and thermostats. There can be multiple computers in a facility.

the year ended 30 June 2021, using the indirect method
0.500 M HCl, also at 35.00Ã ¡ µ C. After stirring, the final temperature is 37.21Ã ¡ µ C. [Assume the total
volume is the sum of the individual volumes and that the final solution has the same density (1.00
g/mL) and specific heat capacity as water (4.184 J/g.K).
(a). Calculate the qsoln (in J and kJ)
(b) Calculate the change in enthalpy, Ã ¢ H of the reaction (in kJ/mol of water formed)
Create a do-while loop that asks the user to enter two numbers. The numbers should be added and the sum displayed. The loop should ask the user whether he or she wishes to perform the operation again. If so, the loop should repeat; otherwise it should terminate
Sample Run1
Enter two numbers: 3 15
Do you want another operation: Yes
Enter two numbers: 45 56
Do you want another operation: No
Output1: Sum = 119
Sample Run2
Enter two numbers: 33 150
Do you want another operation: Yes
Enter two numbers: -56 56
Do you want another operation: Yes
Enter two numbers: 58 15
Do you want another operation: Yes
Enter two numbers: 123 87
Do you want another operation: No
Output2: Sum = 466
The force F (in pounds) acting at an angle θ with the horizontal that is needed to drag a crate weighing W pounds along a horizontal surface at a constant velocity is given by
F = μW/(cosθ +μsinθ)
where μ is a constant called the coefficient of sliding friction between the crate and the surface (see the accompanying figure). Suppose that the crate weighs 150 lb and that μ = 0.3.
(a) Find dF /dθ when θ =30°. Express the answer in units of pounds/degree.
(b) Find dF /dt when θ =30° if θ is decreasing at the rate of 0.5°/s at this instant.
In the temperature range between 0°C and 700°C the resistance R [in ohms] of a certain platinum resistance thermometer is given by
R = 10 + 0.04124T − 1.779 × 10^(−5)T^2
where T is the temperature in degrees Celsius. Where in the interval from 0°C to 700°C is the resistance of the thermometer most sensitive and least sensitive to temperature changes? [Hint: Consider the size of dR/dT in the interval 0 ≤ T ≤ 700.].
Question 03
Write (and draw the graph of) a function which is
(a) Continuous on all points except at x = 1.
(b) Differentiable on all points except at x = 1.
(c) Non-differentiable at five points x = 1, x = 2, x = 3, x = 4 and x = 5.
Construct a Complex structure to represent a complex number with both real and imaginary components being real numbers. Request:
Write functions that calculate the sum, difference, product, and quotient of two complex numbers
Write a function that calculates the sum and difference of two complex numbers simultaneously.
Write a function that calculates the modulus of a complex number
Write a function that displays a complex number in the correct format (a+bj where a is the real component, b is the imaginary component)
