Thiscontainer could be displaced vertically in order to change the water level. We would thenmake a tuning fork vibrate above the pipe and change the water level until the resonance wasat maximum intensity.Hypothesis: The

Dc circuits and Ohm’s law of measurments Helina Wolfe Tannaz Farnoudi and Najah Rouse Physics 246-205 Professor Joe Renaud 09/23/13 Word count:1453 Abstract: The aim of this experiment was to understand the relationship between the variables of Ohm’s law and how they are part of an operation of an electric circuit. Introduction: This experiment was done in two parts. The first part consisted of understanding how to determine the current‚ voltage and resistance

Technology Ohm’s law & resistors in parallel & in series Lab 4 Class: PHY 1434-E475 Due date: March‚ 13 20144 Group Names: Hisham Sageer Objectives: Our object is to confirm Ohm’s law by analyzing the dependence of the electrical current as a function of voltage and as a function of resistance. Also‚ we studied the current flow and voltage in series and parallel. Finally‚ the lab determined the equivalence resistance of series and parallel combination of resistors

In this experiment we tested the idea that no matter what the size‚ shape‚ color‚ etc. of the object if it would still experience the same constant acceleration throughout its fall (short distance). The constant downward acceleration it experiences

HL Vectors Notes 1. Vector or Scalar Many physical quantities such as area‚ length‚ mass and temperature are completely described once the magnitude of the quantity is given. Such quantities are called “scalars.” Other quantities possess the properties of magnitude and direction. A quantity of this kind is called a “vector” quantity. Winds are usually described by giving their speed and direction; say 20 km/h north east. The wind speed and wind direction together form a vector quantity

The first slinky’s mass was weighed‚ using a scale‚ and its tension was measured using a force measurer 2. The slinky was stretched to 4m. 3. The linear mass density was solved for‚ by dividing the mass by the length. 4. The theoretical velocity was solved for‚ using the equation

Vector Analysis Definition A vector in n dimension is any set of n-components that transforms in the same manner as a displacement when you change coordinates Displacement is the model for the behavior of all vectors Roughly speaking: A vector is a quantity with both direction as well as magnitude. On the contrary‚ a scalar has no direction and remains unchanged when one changes the coordinates. Notation: Bold face A‚ in handwriting A . The magnitude of the vector is denoted by A A
