Where‚ F = the restoring force used to displace the mass. K= the spring constant. X = the displacement of the mass with respect to the equilibrium. The most commonly encountered form of Hooke’s Law is probably the spring equation‚ which relates the force exerted by a spring to the distance it

The wheelchair experiment introduced me to a world that I have never known. I have never been in a wheelchair or been affected by any form of hearing‚ visual‚ or physical disabilities. So‚ this experiment caused me to really think about how the layout of a space‚ weight of doors‚ etc. could affect someone. While using the wheelchair‚ I felt as if I was in the spotlight every time I entered a room or crossed paths with a group of individuals. People would look on as I posed in the wheelchair and give

During World War II‚ German doctors and physicians conducted harmful and cruel experiments with victims of the Holocaust; mainly in the concentration camp “Auschwitz.” Nazis’ goals were to improve their medical science‚ prove that they were the “Master Race‚” and they also wanted to have better treatments for the personnel of the German Military. The experiments performed were often deadly‚ but the physicians didn’t care‚ and tested the prisoners anyway. Some of the many victims were Jews‚ Romans

Materials and Methods In the experiment‚ a frog was obtained and dissected in a way to expose its heart and then tested using Lab Tutor software‚ a force transducer‚ and the PowerLab hardware (ADInstruments 2014). Frog dissection: Frogs that had been killed by being double-pithed were dissected as described in Lab Tutor. The frog was pinned down with the ventral side up. A longitudinal and a lateral incision were made along the frog’s abdomen. The skin was peeled back and the tissue and sternum

Psychology Experiment No. 2 Effect of Inconsistency of Objects in Scenario on Perception Introduction: In our everyday lives‚ we are used to seeing objects within their particular characteristic scenarios. For example‚ it is nothing to wonder if we see a person browsing the internet in a computer lab or a car speeding on a road.

Osmosis Experiment Subject: Professor Egg-avier Duration: 3 weeks (Oct 2nd – Oct 16th) Week 1 On October 2nd my group was giving a raw egg (weighing 58.8 grams) and placed it into a clear mason jar with 200mL of vinegar. The ph levels of our vinegar equaled a 2 which tells us that vinegar is a fairly acidic liquid. Once submerged in the vinegar‚ little bubbles began to appear around the egg’s shell. We believed this to be carbon dioxide escaping from the shell. We left our egg to sit in the
