Having minor homework questions or simply want to make sure your homework answers are correct? Then use our free service to get quick answers to your homework questions in mathematics, physics, programming, economics, chemistry and biology. We already have a database of multiple homework questions and answers you can look through . If you can’t find the solutions to your homework problems, then post your homework questions and find a well-formulated answer from a professional within a very short timeframe.
Please save your time and DO NOT send us your full assignments or not precise, well stated questions in mathematics, physics, programming, economics, chemistry or biology as they will be ignored. In this section we can answer only your short questions of qualitative, primary theoretical nature (for FREE!). Use filters to display the questions to a particular subject or section. By entering your e-mail in the box "Search" you can browse the questions posted exclusively by you. Do not worry if you cannot find your question in the list after it has been submitted; every question is being checked by a moderator and appears in the list only after its approval.

Freely moving non-relativistic particle has a relative uncertainty of the kinetic energy of about 1.6 ∙ 10^(-4). Estimate how much the coordinate uncertainty of such particle is bigger than its de Broglie wavelength.
Estimate the minimum kinetic energy of an electron localized in the area of size l = 0.10 nm.
Estimate the minimum error, which can determine the velocity of electron, proton and the uranium atom, localized in the area with the size of 1 micron.
Explain the features of the Compton effect:
a) necessity to use a sufficiently short wavelength X-rays to check the formula of Compton shift;
b) independence of the magnitude of shift from the kind of substance;
c) existence of a undisplaced component in scattered radiation;
d) increase of the intensity of shifted component of scattered radiation with the decrease of material atomic number , as well as with the increase of scattering angle;
e) broadening of both of the components of scattered radiation.
There is a line and five points, which do not belong to this line. Two of these points belong to the first half-plane, and three other points – to the second half-plane. Each pair of points is connected by a segment. How many segments intersect the line?
There is a line and three points (A, B and C), which do not belong to this line. The segment AB intersects the line, and the segment AC doesn’t intersect it. Does the segment BC intersects the line or it doesn’t?
Can the points A, B and C belong to the same line, if AB > BC, AB > AC, and AB < AB + BC?
Can the points A, B and C belong to the same line, if AB = 1,8m, AC = 1,3m, DC = 3m?
I'm interested in getting help with an assignment involving Access. I have to create a database. All of the information is given. I have tried to download software from the Internet to do this assignment, but nothing has worked. So I'm in a pickle.
How to link a C++ code to a HTML page?? I am doing a project on Internet banking.
