Lab 4: Methods of limits Elizabeth Bryan Florida State University Lab 4: Method of limits. Sound waves are created when an object vibrates. They have two main components: frequency (pitch; measured in Hertz (Hz)) and amplitude (loudness‚ intensity; measured in decibels (dB)). The method of limits is a psychophysical method in which a particular dimension of a stimulus‚ or the difference between two stimuli‚ is varied incrementally until the participant responds differently. The change in stimulus

Practical 6 -Determining the Gas Constant Aim: To verify the gas constant as 8.31 J/mol/K ( ) and to calculate the molar mass of butane. Theory: The ideal gas law‚ PV=nRT‚ is used to model an ideal gas‚ which is a gas with no intermolecular forces other than those of collisions‚ perfectly spherical and elastic particles. Although an ideal gas is a theoretical model and so cannot exist in practice‚ most gases behave fairly similarly to an ideal gas. Gases behave more like an ideal gas when they are

Should Highway Speed Limits Be Increased? Should highway speed limits be increased? Should we strike down every sign that the government posts and uses to regulate the speed limit on the thousands of highways around the country? Should we trust the driving ability of each and every person to drive within a reasonably safe speed? The response that most people lean toward is one of negativity. People automatically assume that the speeds presently posted on our highways are there only for our

Following the Seven Years War‚ Parliament looked upon the colonies as an ATM and began enforcing numerous taxes without their consent. This concept of “taxation without representation” was the prompting factor for the American Revolution. Parliament justified their action by “virtual” representation: stating its members had the best interest of the colonist in mind. However‚ the hypocrisy of Parliament is evident in the Tea Act of 1773. The East India Company was granted a monopoly to import tea

may not be saturated and tissues would fail to get enough oxygen. In order to combat this‚ animals can alter the amount of oxygen carried in their bloodstream by increasing the concentration of hemoglobin‚ increasing the hematocrit‚ or by changing how well hemoglobin binds oxygen. Animals that travel from low elevations to higher ones usually increase the number of red blood cells and increase DPG concentrations so that hemoglobin binds oxygen less well (which increases delivery). However‚ this is
