Research Question: What is the effect of external temperature(c) on the rate of hand squeezes on hand strengthener in the dominant hand of homo sapiens? Independent variable: External temperature of water. ( 8, 16, 24, 32, 40 ) Dependent Variable: Rate of hand squeezes on the hand strengthener. Number of times the strengthener is squeezed (50) / time it takes to complete squeezes (seconds) Controlled Variable: Rate of hand squeezes (50) / time (seconds) in regular classroom without hand

1. Degree measure is more commonly used by the average individual. Most people can just look at an angle and tell its 90 degrees. However, measuring angles in radians is not as common. It is more so used in higher more advanced maths. Degrees measure the rotation of an angle while radians measure the angle of the center of a circle, or an arc. I think degrees would be a better choice in terms of measuring due to the fact that it is simpler and more commonly known about than radians. 2. No, Adam

The best way to observe the effects of training is in exposure to cold air as well as cold water. Makinen (2010) tested numerous amounts of subjects in different exposures such as cold air as well as exposure to cold water. Possibly over hundreds of people were tested as a total for her experiment. Her results consisted of multiple explanations and responses towards the different temperatures and climates. Makinen et al (2008) tested 10 male subjects who were exposed to control 25° Celsius and

Part A: Effect of Concentration Gather materials. Prepare hot-water and ice-water baths, use 250 mL beakers and fill them halfway with tap water. Place one on a hot plate and heat to 65-70 degrees Celsius for use in Part B. In a second 250 mL beaker, add water and ice to make an ice-water bath for use in Part B. Add 3 drops of iron (III) nitrate solution to different spots in the Petri dish. Swirl the solution until the color is the same throughout the entire solution. Add ½ pea-size amount of

Temperatures in the Artic Over the last several years, researchers in the Arctic have begun closely monitoring the temperature and the alarming effect it seems to be having on the climate. According to researchers, the Arctic is having abnormally high air temperatures and sea surface temperatures, which are causing the melting of the ice leading to record breaking lows of ice. To the north, the Arctic is almost 100% ice and snow. The southern parts of the Arctic are where you can find more vegetation

Identifying an unknown substance can be accomplished with the use of multiple scientific tests, which help narrow down the possibilities of the unknown compound. The unknown substance that I was given was unknown number A84841BIR, and posed to be a real challenge since I needed to test two different molecular combinations for this specific substance. Once the number of moles in substance was calculated using the ideal gas law, I divided it from the sample mass number after heating and obtained that

1. What is your evaluation of each of the three businesses? What is your evaluation of the managers who run them? French Division Units  ('000) Profit Plan (Master Budget)  Profit before Interest and Taxes = 1027 Flexible Budget  Profit before Interest and Taxes = 2,002 But Actual Profit earned = 1242 which is 760 less than profit anticipated in flexible budget. Increase in the profits above the actual budget can be attributed to 20% increase in sales in 2009. Although Jean’s profits

Results The hypothesis tested in this experiment was, if the temperature of enzyme catalysis were increased, then the reaction rate would increase, because enzyme-catalysis reacts by randomly colliding with substrate molecules, and the increase in temperature increases the speed of collision or reaction rate. The final data collected for the experiment was positive with my hypothesis. The coffee filter, covered in potato solution, sank and rose at a faster pace in the hydrogen peroxide when the temperatures

Introduction In the 19th century, Samuel Hunter Christie invented the diamond method for circuits, the initial idea to the Wheatstone bridge. However, bridge circuits, circuits with parallel resistors, bridged by a branch between them, were used to measure small voltages; but, the Wheatstone bridge is used to measure an unknown resistance using all the others three known resistance in the circuit. During the lab, the Wheatstone Bridge concept for a bridge circuit was used to determine the unknown

The independent variables are the following: * Boiling temperature of 1 ½ cups of tap water (Fahrenheit) * 3 ½ oz. of each type of chocolate * Same pot, containers, and thermometer used in a consistent manner The dependent variables are the following: * The amount of time each chocolate spends in the boiling water * How long the thermometer
