All minerals have four properties: 1. All minerals are naturally occurring 2. All minerals are inorganic (that means non-living) 3. A different chemical formula can be written for each mineral and that formula is constant for that mineral. ex. Galena is PbS- that is it has one lead atom (Pb) and one sulfur (S) atom in each molecule. 4. Most minerals have an unique crystalline shape given the right growing conditions (like in a cave). Compounds are substances that has two or

studied at Cambridge. In 1665-6 the fall of an apple is said to have suggested the train of thought that led to the law of gravitation. He studiedthe nature of light‚ concluding that white light is a mixture of colours which can be separated by refraction‚ anddevised the first reflecting telescope. He became professor of mathematics at Cambridge in 1669‚ where heresumed his work on gravitation‚ expounded finally in his famous Philosophiae naturalis principia mathematica (1687‚Mathematical Principles

TYPES OF MAGNETIC MATERIALS Paramagnetic materials have a small‚ positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons‚ and from the realignment of the electron paths caused by the external magnetic field. Paramagnetic materials include magnesium‚ molybdenum‚ lithium‚ and tantalum

1. The Effect of Pilocarpine and Tropicamide on Human’s Pupil 2. Throughout the experiment‚ we have learned how to measure the pupil diameter using a pupillometer‚ how to measure the near point of accommodation using a accommodometer and how to demonstrate the pupillary light reflexes by shining the light on the pupil. Besides that‚ we have learned the effect of 1% tropicamide and 2% pilocarpine on the human’s pupil and how the drugs will affect the pupil diameter‚ near point of accommodation

Define the following terms: 1. Horizontal Cable : A type of inside cable designed for horizontal use in non-plenum areas. While horizontal cable must be fire retardant‚ the National Electrical Code (NEC) specifications are not as demanding as those governing the use of plenum cable or riser cable. See also NEC‚ plenum‚ plenum cable‚ and riser cable. 2. Backbone Cable : Backbone cabling is the inter-building and intra-building cable connections in structured cabling between entrance facilities

I. Introduction There have been many philosophical discussions that try to explain the creation of the universe. Paley attempts to illustrate the creation of the universe through an analogy to argue for intelligent design. However‚ Hume disagrees with the analogy and believes that the universe and an object such as a watch or house are incomparable when looking at their formation specifically. Hume is able to demonstrate that the design analogy is somewhat incoherent. II. Paley Paley believes
