Why will insulators affect how long a test tube of hot water stays hot? Background Information I know that there are many different ways of insulating this test tube‚ shiny foil can be used because it’s a poor emitter of radiation and it will reflect escaping heat by reflecting‚ because this method is used in flasks to keep hot drinks warm. Though it is a good conductor so will lose heat through to surfaces its touching but it shouldn’t matter because it will be touching air and glass which both

In 1932‚ in the area surrounding the Tuskegee‚ Macon County‚ Alabama‚ the U.S. Public Health Service created a government funded study to be conducted on 600 African American men that were lured in with the promise of free health care. What this study consisted of was testing these men for the sexually transmitted disease syphilis. After the testing was completed 399 infected and 201 healthy men were not told anything except that they had a condition called “bad blood” and that they must continue

EXPERIMENT 201: WORK‚ ENERGY AND POWER John Michael A. Ramos‚ Phy11l/A5 Abstract The essential conditions to be satisfied for work to be done are: Some force must act on the object. The point of application of force must move in the direction of force. W = F x s. SI unit of work is joule. Energy is the capacity to do work. The two types of mechanical energy are kinetic energy and potential energy. Kinetic energy is the energy possessed by an object by virtue of its motion. Potential energy is

Breaching Experiment In the eye contact experiment I decided to do this in a room with about six of my friends while watching the All Star game‚ I used my Girlfriend. I waited until everyone was focused on the game and then begin to stare at her from across the room‚ at first her reaction was to wave at me and smile then she started to look around to see if I was starring at someone else‚ then she told her best friend "I don’t know what’s his problem‚ he is being too weird."

English 10a 6 March 2012 Tuskegee Experiments This is possibly one of the most inhumane things to ever happen in the 20th century in the Untied States. The experiments that took place were the root of medical misconduct and blatant disregard for human rights that took place in the name of science. The ghastly medical expirements that took place between 1932 and 1972 was merely an observation of the different stages of syphilis. The men in these experiments for the most part were illiterate

The graph should show an increase in arbitrary units the further away from the light source the beaker is because the greater the distance from the light source‚ the lower the light intensity and so less photosynthesis
