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

1. A single disturbance that moves from point to point through a medium is called a ___. a. period b. periodic wave c. wavelength d. pulse Answer: D A wave is a continuous and repeating disturbance of a medium and a pulse is a single disturbance. 2.

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

Critical Thinking Stanley Milgram Experiment I feel the reason the Milgram Experiment subjects were lacking the moral and critical thinking of how they reacted to the experiment was a multitude of things such as. The subjects felt they had to because they were being told to by “people of authority” They also felt that since they were participating in the experiment and they were only doing “as told” then they were okay to proceed. Some also stated that do to the trust they had for the school and

I don’t think this experiment should be replicated today. The reason being is that the Generation we have today has a different mindset and that the experiment is unethical in my view. In 1961‚ Milgram was able to make the participants agree with the experiment. These results led to people trying out these trails because the participants knew the shock would be painful but not dangerous. With that being said‚ it shows you the mindset of the people during that time. People were laid back and were

Griffith’s experiment‚ reported in 1928 by Frederick Griffith‚[1] was one of the first experiments suggesting that bacteria are capable of transferring genetic information through a process known as transformation.[2][3] Griffith used two strains of pneumococcus (Streptococcus pneumoniae) bacteria which infect mice – a type III-S (smooth)
