How The Scientist Discover The Interior Of The Earth Two ways that Scientist may study and find the interior of the Earth are with Meteorites and Magnetic Fields. The scientist may use meteorites to discover the interior of the Earth’s earlier solar system by studying the meteorites that arrived on the Earth. The scientist might use magnetic fields by the science advances which involves measuring the ocean and coming up with a hypothesis. Therefore‚ the meteorites and the magnetic fields all

Projectile Motion Vectors There are multiple ways to represent an object’s motion. If the motion is two-dimensional and lies in a plane‚ some representations include: (1) recording x and y coordinates of the object at different times in a data table; (2) displaying the object’s x and y locations at regular time intervals on a diagram; (3) drawing vectors showing displacement‚ velocity‚ and acceleration and their x and y components at different times. (4) using vector equations to represent

Arlind Mara Paper Towel Lab Report AP Biology 15 September 2011 Which Towel is The Quicker-Picker Upper! To determine which of the most popular paper towel brands such as Bounty and Marcal would be the Quicker-Picker-Upper I conducted the following experiment during which I dipped 6in X 6in squares of paper towels into 100mL and measured the amount of water absorbed by the towels in 20 seconds. After averaging all 3 trials for the paper towel brands that I tested I arrived to the conclusion

The Michael addition is a reaction named after Arthur Michael. Discovered in 1887‚ this is a carbon-carbon bond making reaction. The result of the Michael addition is a 1‚4 addition of a nucleophile to an alpha‚ beta-unsaturated carbonyl carbon compound. A 1‚4 addition is also commonly referred to as a conjugated addition. Another result of this reaction is a 1‚2 addition of a nucleophile. Some of the common attacking nucleophiles used in this reaction are enolates. Enolates‚ a negatively charged

The purpose of this lab that was completed was to observe standing wave patterns in clamped strings‚ and understand the effect of the standing wave frequencies of changing the length (L)‚ tension (T)‚ and linear density (p) of the strings. Standing wave patterns in strings are observed at certain excitation frequencies for special values of L‚ T‚ and p. A standing wave can be defined as a vibration of a system in which some particular points remain fixed while others between them vibrate with the
