It bends or refracts light rays entering the eyes. C. It is the site of attachment for the extraocular muscles. D. It helps to maintain the shape of the eye. Answer Key: B Question 2 of 20 1.0 Points The border between the transparent edge of the cornea and the white of the fibrous sclera is the: A. pupil. B. anterior chamber.
Finally, after purchasing all of the supplies it is time to build your telescope. Paint the inside of your tube black. Then take the two magnifying glasses, hold one magnifying glass (the bigger one) between you and the paper. The image of the print should look blurry. Take the second magnifying glass and place it between your eye and the first magnifying glass.
Liam Stephenson controlled assessment Introduction In my course work I will be looking at how the thickness of a converging lens affects the focal length. The factors involved in this experiment are: light, lens curvature, refraction and thickness of the lens, these will determine the focal length; the focal length is the length between the focus and the lens. Light-visible light is an electromagnetic wave in the electromagnetic spectrum The speed of light depending on the medium it is in, for example the speed of light is 300,000 km/s however when light travels through other medium such as water or glass the speed of light is slowed this is because water and glass is denser than a vacuum of air. Due to it being more dense and a change in speed, the direction of the wave will change this is

Employed the use of Visual PinPoint in order to astrometrically reduce the images and to embed World Coordinate System data into the FITS header. Utilized data found in Sergeant (1974) paper concerning globular cluster positions. Used a procession calculator, found online, to convert the coordinate system from the outdated 1950 Epoch to the 2000 Epoch. Proceeded to plug in Sergeant's data into the calculator and re-checked for any errors. Used a digital development filter set to a kernel low pass more in MaximDL.
This relationship is specific to the gases that are considered “ideal”. For a gas to be considered “ideal,” it will have no interactions with other molecules and the molecules that make up the gas won’t take up any space. The Ideal Gas Law equation is PV=nRT. “P” stands for pressure, “V” is for volume, “n” gives the number of moles, “R” is the gas constant and “T” is for temperature. The ideal gas constant value is 0.082057 (L x atm)÷(mol x K).
The null hypothesis is a hypothesis that states that nothing will happen, no matter what happens to the independent variable, the dependent variable will not change. The working hypothesis is a hypothesis that states that the independent variable will affect the dependent variable. The data in a experiment supports the working hypothesis and falsifies the null hypothesis by proving that the independent variable will affect the dependent variable. An endotherm is a living organism that has built in mechanisms that maintain a constant body temperature. An ectotherm is a living organism who’s body temperature fluctuates with the surrounding or ambient temperature.

Philosophy: the love of wisdom The study of first causes, the ultimate nature of things. Because philosophical principles are ultimate/primary, there is nothing that precedes them. Knowledge is associated with science (to know) – person has science not by knowing a fact, but the reasoning for the fact, or cause. Wisdom is knowledge through causes – knowledge of first causes. Wisdom does not require any kind of experience beyond normal experience.
Accuracy vs Precision By Charlia K Rice Accuracy and precision go hand in hand when it comes to making sure that things are done properly in the science field. Accuracy measures the closeness of the amount to the amounts actual value. Precision is the ability to repeat something without changing anything and getting the same results. When measuring something it can be accurate and not be precise, and precise but not accurate, neither one of them, or it can be both of them. If something contains precision and accuracy then that makes it the perfect experiment.
