A small 0.10 kg block starts from rest at point A, which is at a height of 1.0 m. The surface between points A and B and between points C and D is frictionless, but is rough between points B and C, having a coefficient of friction of 0.10. After traveling the distance â„“ = 1.0 m, the small b ... Read More

While I took occasional help for my different assignments from HelpWithAssignments, I kept on wondering whether they could actually help with my dissertation paper. When I first approached them, they sounded confident and they already knew what is needed to be done. That was very relieving as even before my professor told me what to be done next, the thesis help tutor knew what to do. I have got an “A” in my master’s dissertation report and now I have assigned them by PhD thesis paper also.
I was struggling with the deadlines of my assignments and increasingly felt at a loss with my Asian Legal Studies assignments. 24 hours in a day were not enough to do the research and structure the assignment essay. At HelpWithAssignment the tutors understand my deadlines and I have never had them delay.
The object oriented programming languages like C++ and Java were a nightmare for me and my professor rushed off with her lectures so fast that I couldn’t catch up with the syllabus. Then once HwA started helped me out with my computer science assignments I got more time to understand how the things summed up. They did not only just write the codes on my behalf but when I enquired explained to me every step individually. The experts here are really helpful and I will always remain grateful to HwA for all the nice grades I have got in my graduation and post graduation in computer science and technology.
I was clueless about my post tracheostomy and laryngectomy patient care assignment, when I came across HwA. Never really believed in the beginning that they have a separate unit for respiratory system assignment solutions and the experts here are really helpful.
I really needed help writing my power engineering assignment for my MS in Electrical Engineering program but I did not want to pay a fortune for it either. At HwA I have found the perfect solution for my power engineering assignment questions at a price that is reasonable. There is no compromise in the quality of the assignments even if they have low prices as compared to the other online assignment help providers that I have seen.
