Parachute experiment Aim: The aim was to find the effect of holes on a parachute‚ varying their size and number. Hypothesis: 1. By increasing the number of holes‚ the time it will take to the parachute to reach the ground will be longer and its flight will be more balanced. 2. By increasing the size of the hole on the parachute‚ the time it will take to the parachute to reach the ground will be shorter and its flight will be less balanced. Apparatus: - garbage bag (squared shape

the hot water from combining it with the cold water. As discussed in a page titled Heat Capacity2‚ the heat capacity is defined as the amount of heat it takes to raise the temperature of a substance by one degree (in this case C). In the experiment performed in lab‚ the heat capacity of the calorimeters was calculated by subtracting the heat gain from the heat loss and then dividing that by the difference in the temperatures between cold water and the combination of the hot and cold water‚ . The heat

Why does the addition of sodium chloride elicit and action potential? The addition of sodium chloride elicits and action potential because it increases the concentration of sodium outside of the cell which generates an active transport of sodium into the cell and potassium outside of the cell. 8. What was the effect of ether on elicitation and an action potential

Adsorption Experiment This paper will be discussion the adsorption experiment conducted in Dr.O lab class. This paper will cover what Chitin/Chitson are but before explaining what these are it is best to get an understanding of what adsorption‚ absorption and sorption are. Adsorption is the accumulation of gases‚ liquids‚ or solutes on the surface of a solid or liquid. This binding is very weak. Almost anything such as fluids that dissolves can break the binding of the molecules. In addition adsorption

ABSTRACT The Stroop experiment focuses on the interference of a person’s reaction time on a given task. Certain tasks can be performed with more accuracy due to the fact that our brain becomes conditioned to react automatically after exposure of the stimuli. In this particular experiment‚ eight-teen college students underwent the Stroop experiment in individualized laboratory rooms. Four students were male and fourteen were females. The experiment helped us examine the horse race model

The purpose of this lab that was completed was to observe standing wave patterns in clamped strings‚ and understand the effect of the standing wave frequencies of changing the length (L)‚ tension (T)‚ and linear density (p) of the strings. Standing wave patterns in strings are observed at certain excitation frequencies for special values of L‚ T‚ and p. A standing wave can be defined as a vibration of a system in which some particular points remain fixed while others between them vibrate with the

is by eating chocolates. To confirm this assumption‚ the experimenter‚ Victor Seo has developed an experiment to prove the hypothesis: “people who consume lots of chocolate will produce more acne than people eat less chocolate. 400 students of teenagers with grades ranging from 9 to 11 will be examined divided into four groups each consuming 1 bar‚ 3 bars‚ 6 bars‚ or 10 bars daily. This experiment will remain over a time period of a month. Meals will be served in equal amounts and the amounts of

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
