In a right triangle‚ the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. (a^2 + b^2 = c^2 (Page 433) Pythagorean Triple A set of 3 positive integers A‚ B‚ and C that satisfy the equation A^2 + B^2 = C^2 [Ex. (3‚4‚5) (5‚12‚13) (8‚ 15‚17) and (7‚24‚25)] (Page 435) Converse of the Pythagorean Theorem If the square of the length of the longest side of a triangle (hypotenuse) is equal to the sum of the squares of the lengths of the other two sides (legs)

LABORATORY REPORT Activity 2: Twitch Contractions and Summation PREDICTIONS Effect of Muscle Fiber Length on Contraction 1. As muscle fiber length increases: contraction force increases‚ becoming maximum at an optimal length‚ then decreasing at longer lengths. Effect of Stimulation Frequency on Contraction 2. As the frequency of stimulation increases‚ the force of contraction: increases. MATERIALS AND METHODS Measurement of Threshold Stimulus 1. Dependent Variable: contraction force

the resistance of a wire is affected by the length of the wire. Theory What is resistance? Resistance is a force which opposes the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit. The circuit itself can resist the flow of particles if the wires are either very thin or very long. e.g. The filament across an electric light bulb. How is it measured? The resistance of a length of wire is calculated by measuring the current

the resistance of a wire at different lengths to see whether or not a longer wire has a larger resistance than a shorter wire. Apparatus: Wire Voltmeter Ammeter Battery 2 crocodile clips Metre rule Variable resistor Diagram: Variables: Length Thickness Resistance Material The material and diameter of the wire needs to be kept constant to keep the test fair as we are investigating resistance. The independent variable will be the length of wire as we will be changing it to

Introduction This experiment is about to test how will the nichrome wire effect the ampere of the electric current. All the possible factor that will effect to the volt of the current • The Length of the wire • The Diameter of the wire • Temperature • Magnetism Aim To determine the effect of the length of the wire on the ampere of the electric current. Hypothesis Nichrome is an alloy(a metal made by combining two or more metallic elements) that is made out of 80% nickel and 20% chromium

likely to be compliant with thigh-length SCD’s than knee-length SCD’s. The most common reason for noncompliance with thigh-length SCD’s was that the devices were hot and itchy. Thigh-length SCD’s are less likely to be reapplied after ambulation. Thigh-length SCD’s also have a tendency to be fitted improperly around the patient’s upper leg. The size of the SCD is either too large or too small causing discomfort. This is a common reason for noncompliance. Knee-length SCD’s are lighter and more comfortable

Z. K. L3 A THE SIMPLE PENDULUM • General Background: A mass m hanging from a string whose length is L and a pivot point on which this mass is fixed are what a simple pendulum (which was discovered during the 10th century by Ibn Yusuf) consists of. During the 17th century‚ it is developed by some physicist‚ especially by Galileo. When the mass hanging from the string is released with an initial angle‚ it starts to move with a periodic motion. The motion can be approximated as a simple

the extent of the effect of another variable to it‚ as in an experiment. In osmosis lab‚ the dependent variable is the length of the potato. The controlled variables are the amount of water‚ amount of salt‚ and the size of the potato. If the potato is placed in a higher salt concentration‚ then the potato will decrease its size. We started the lab by cutting the potato core length (44 mm). Each potato core are placed in test tubes. The test tubes have different salt concentration‚ test tube 1 has
