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.

Solve for y(s), the Laplace transform of the solution y(t) to the given initial value problem
y"+y'-y=t3;y(0)=0, y'(0)=0?
How to do proof by contradiction?
Cosmic rays consist mostly of protons, middle energy ξ of which consists of few billions of electron volts. Intensity I stream of protons, reaching Earth's atmosphere is equal approximately to one proton on square centimeter per second. To evaluate the time needed for protons of cosmic rays raised the Earth’s potential so they could not reach Earth’s surface because of electric repulsion. Explain, why even after that time protons of cosmic rays reach Earth’s surface.
Liquid column put in conical tube moves by itself to more narrow part when it wets tube walls and to wider part when it does not wet the walls. Explain the phenomenon.
Is the ideal gas heated up or cooled if it expands at constant pressure?
I m currently doing B.Tech(VIII sem.) in Computer science.
Please suggest some unique project ideas for final year. I wanted to create a web application in PHP
A man, though slowly, can bring a heavy barge on the water into motion, if he pulls by the rope tied to it. He is not able to do that with heavy body, lying on earth, even though his body noticeably less than the weight of the barge. Why?
Parallel sided plate from hard dielectric is places between the plates of flat air condenser in such a way that between it and plates of condenser air clearance was left. How will change the force of attraction between the plates of condenser?
The space between the facing of a long cylindrical condenser is filled by homogeneous dielectric with weak electro conductivity. When the condenser is charged in dielectric electric charge flows from one armature to another. Neglecting edge effect, find the tension of magnetic field between the facings.
Flat air condenser, facing of which are considered to be two identical disks is charged to high potential difference and after that is disconnected from the voltage source. In the center on condenser happens a breakdown and condenser discharges. Considering quasisteady discharge and neglecting homogeneity of the field on edges of the condenser, define stream of electromagnetic energy, flowing from the space between the facings. Discuss the phenomenon from the point of saving and transformation of energy.
