    Prior to the 1500’s‚ Europeans lived their daily lives relying greatly on the authority of the church and ancient Greek and Roman authors‚ basing their perception of the world directly by the Bible. However‚ these institutions of authority tended to reject new ideas due to the fear of losing power once contradicting theories take the place of those written in the Bible. For most Europeans‚ change was frightening and difficult to grasp‚ causing very few individuals to challenge the church by making

    Matter can be quantified in three different ways. The first way is to count how many of something you have‚ For example‚ you can count the number of shirts in your closet. The second way to quantify or measure matter is to determine its mass. For example‚ you can buy bananas by the pound. The third and last way to quantify or measure matter is to determine its volume. For example‚ people by gasoline by the gallon. Chemists use a unit that is a certain number of particles. This unit is known as the

    Completion Problems (Elasticity) 1. A steel wire of length 4.7m and cross-sectional area 3×10-5m2 stretches by the same amount as a copper wire of length 3.5m and cross-sectional area of 4×10–5m2 under a given load. What is the ratio of the Young’s modulus of steel to that of copper? For Steel l1= 4.7 m‚ a1 = 3.0 x 10-5 m2 Y1= Fl1/a1∆l Y1= (F x 4.7m)/ (3.0 x 10-5 x ∆l) For Copper L2=3.5 m‚ a2 = 4.0 x 10-5 m2 Y2= (F x 3.5m)/ (4.0 x 10-5 x ∆l) Dividing Steel by Copper Y1/ Y2

    of Galileo’s. Toricella concluded that the air pressure explains why the water would only go as high as thirty four feet. Although there was no direct evidence to prove Toricella’s theory to be true‚ it was proven indirectly with the use of a mercury barometer‚ which made length measurements easier to understand. Shortly there after‚ the principle of verifiability was introduced and defined as wanting to describe the conditions that make a particular theory true. The main objective to the principle
