whats the relationship between the temperature of water and its refractive index?

When 2 ionic solutions are mixed and the reaction gives a sparingly soluble product, it is possible to write an ionic equation for the mixing of the solutions.

I am doing an investigation on circular motion and have chosen to study the relationship between mass and its circular horizontal velocity Can anyone tell me what the actual relationship between the 2 variables is so that i have a good reference point. Other websites do not seem to offer a...

What sort of substances does berrylium form a covalent bond and with which substances is it ionic. i know that berrylium usually does form covalnt bonds, but sometimes i find it being referred to as an Be2+ ion. Also many berrylium compounds are good conductors of electricity such as...

Homework Statement how do you shift the graph y=x^2 to give the equation below Homework Equations y = 3(2x+1)^2 + 2 The Attempt at a Solution I know it involves the following steps: -shift the graph 2 units up -shift 1 unit to the left -dilate to the x-axis scale factor 0.5...

glass as an insulator? i have lately done some reading on the properties of glass and have seen threads where some say glass is an insulator and others say it isn't. what is the real fact about the thermal conductivity of normal glass, e.g. the wine glass or the glass beaker. are they really...

Hi all I have been studying vectors lately and am very confused as to how to : finding relative velocity adding and subtracting vectors i am able to understand the basics of it but cannot get a hang of the harder questions. Does anyone know any website or example that can help...

does anyone have any worked out solutions for the Australian maths competition for the years 2002-2009. i really need them and would be really greatful if anyone could provide me with some or the name of a website that has these papers.

Even if that is true, there is still the fact that oil is not something that is produced over a short time. In addition to this, human populations are exploding and also demand for oil is bound increase greatly. Even if there is 'yyyy' oil left, eventually it WILL GET OVER and as i have...

I feel that whether global warming is true or not, there is still a necessity for us to change our lifestyles. Let's face it, everyone knows that coal and oil are not unlimited and when these resources do run out, we are in a lot of trouble. It is because of this that we must see that the...

This is not a matter of opinion, but is rather than a case of trying to develop an effective argument. What i am asking is if an effective argument is given that all colours are equal, will the adjudicator still accept such a thing?

i was wondering if in a debate you can be neutral between both sides. example: the topic is 'red is better than green' Is it possible to say that all colours are equal?

is green better than red? Over the past couple of days, i seem to have noticed that sometimes, people like green better than red. I have been thinking about it and felt that it should be brought to discussion as to why green seems to be better. I know it sounds rather strange, but when you...

Hi all Can anyone give me some websites which are on problem solving. When i mean problem solving, i mean logical sums not you standard maths problems. Also i want it to be a high school difficulty, not a uni type. Any websites are greatly appreciated

i am not interested in a real accelerator, just one that can demonstrate the concept.
