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.

A 2003 survey showed that 4.6 percent of the 250 Americans surveyed had suffered some kind of identity theft in the past 12 months. Construct a 98 percent confidence interval for the true proportion of Americans who had suffered identify theft in the past 12 months.
assume stm is supplied at 850 psi @830deg Fto a condensing turbine with a vacuum of 26"Hg. Find the work the turbine does in units of btu/lb
can u please help me to find a new technology that use solar energy and convert is to electrical? something new?? i need to do research about that technology
if x^y.y^x=1 then find dy/dx
salam sir please help me by providing the answer of below question.
how many triangles can be formed by joining 12 points ,7 of which lies on the same straight line.
The driver of the compact car in the previous problem suddenly applies the brakes hard for 2.0 s. As a result, an average force of 5.0x10^3 N is exerted on the car to slow it down. The previous problem has a car that weighs 725 kg that is moving at 115 km/h that has a momentum of 2.32x10^4 kgm/s eastward. Also has another car that weighs 2175 kg with a velocity of 38.4 km/h. What is the change in momentum; that is, the magnitude and direction of the impulse, on the car? Complete the "before" and "after" sketches, and determine the momentum and the velocity of the now.

calculate the pH of a solution formed by mixing 40ml of 0.1M HCL with 60 ml of water.
On July 25, 1956, the linear Andrea Doria, of mass 4.1x10^7 kg, was heading west at 40 km/hr. it collided off Nantucket Island with the Stockholm, of mass 1.7x10^7 kg, sailing 30 km/hr in the direction 20 degrees east of north. the bow of the Stockholm temporarily lodged in the side of the Andrea Doria; that is, the collision was perfectly inelastic.
a) find their common velocity (speed and direction) just after collision
b) what was the loss in kinematic energy due to the collision?
what is 2a-8
