Lab #1: Projectile Motion Purpose: To determine experimentally the initial and final velocities of an air powered projectile. Hypothesis: If the angle of the rocket is launched at 45 degrees than the distance and velocity will maximize. Materials: Rocket launching platform Rocket launcher Rocket body Air pump Safety goggles Rubber washer Nose cone 40‚ 45‚ 50‚ 55 and 60 angle wooden blocks Measuring wheel Procedure: 1. The rocket was assembled by the rocket launcher

A superconductor is a metallic alloy that conducts electricity without resistance‚ below a certain temperature. Once in motion‚ an electrical current will flow in a closed loop within a superconducting material. This is the closest to scientists of a perpetual motion machine. In 1911‚ Heike Kamerlingh Onnes first observed superconductivity. He used mercury and cooled to four degrees Kelvin. When the mercury reached that temperature‚ the resistance disappeared. That meant that the electrical current

Flight is a phenomenon that has long been a part of the natural world. Birds fly not only by flapping their wings‚ but by gliding with their wings outstretched for long distances. Smoke‚ which is composed of tiny particles‚ can rise thousands of feet into the air. Both these types of flight are possible because of the principles of physical science. Likewise‚ man-made aircraft rely on these principles to overcome the force of gravity and achieve flight. Lighter-than-air craft‚ such as the hot

Miriam Yanez Physics 018-01 Literature Review 25 April 2012 Biophysics and protein dynamics have shaped our lives when it comes down to advancements in medicine. In living cells‚ proteins are the main components that keep the organism running at its best with every single protein and enzyme having their own function. The discovery of DNA‚ RNA‚ and other protein synthesis became the structures of life in a new perspective in the smallest ways leading to the continuing studies to uncover more

DNA almost immediately transformed the American Criminal Justice System. Law Enforcement‚ District Attorneys‚ Defense Attorneys‚ Criminal Court and Family Court all work with DNA on a daily basis. DNA that can be utilized in a criminal investigation may be collected from a crime scene in many different forms: skin tissue‚ hair‚ blood‚ semen‚ saliva‚ vaginal fluid‚ anything that may be collected from a human that may contain cells can be utilized and tested for DNA. DNA testing is the most

Groyne Investigation FINAL Report‚ Alice Cearns ABSTRACT The purpose of the investigation is to analyse the effect a groyne has on a beach’s formation and sand deposition‚ and the seasonal impact the ocean has on its shoreline. South Cottesloe beach contains native plants‚ from berry saltbushes to red-eyed wattles; it has accumulated sea wrack and rocky surfaces especially south of the groyne‚ and sand dunes running down to the swash zone. With fences running parallel to the water line‚ this
