is involved with the cannon being fired then the force of gravity would cause the cannon to start to slow down‚ wouldn’t go as far and the direction or trajectory of the cannon ball would be a curved line going down. Purpose: The purpose of this lab is to give the student a better understanding about projectile motion and to understand Newtons theories and laws of motion. We will be firing the plastic ball from the projectile launcher three times from eight different angles from the ground &

reproductive. Orientation is when the organism is placed in their beneficial environment consisting of two behaviors‚ taxis (movement directly towards or away something) and kinesis (random movement). Reproductive is detected using drosophila in this lab‚ it consists of finding courting and mating with another of the species Agnostic behavior is found in a situation where the animal feels threated by another‚ leading to the organism looking bigger or more threatening to the opponent. Within the Agnostic

The Charge/Mass (e/m) Ratio of the Electron PHYS 0212: Introduction to Laboratory Physics Fall 2012 Abstract The experiment conducted demonstrated correlation between the charge and mass of an electron and the behavior of magnetic fields. The lab was divided into four parts. The first three parts were conducted with a compass that was used to locate the magnetic field lines around a bar magnet‚ a solenoid and then a pair of Helmholtz coils. As a result of these trials‚ our observations found

The color intensity was observed by eye and measured using a spectrophotometer. Of the solvents that had beetroot‚ .9% saline had a color intensity of .002‚ 1% acetone had .009‚ 25% acetone produced an intensity of .119‚ 50% with the intensity of .647‚ 1% alcohol had .006‚ 25% alcohol had .022‚ and 50% alcohol had .177. The highest concentration of acetone inflicted more damage on the membrane of the beetroot causing it to leak its betacyanin in a higher intensity than any of the other solvents had caused. Acetone and methanol can both cause
