PHYSICS FOR SCIENTIST AND ENGINEERS LABORATORY EXPERIMENTS EXPERIMENT 5 (Assignment) EXPERIMENT 5 – MAGNETIC FIELDS OBJECTIVES 1. To study the workings of magnetic fields. 2. To determine the North and South poles of magnets and magnetic field lines. 3. To understand the attractive and repulsive forces acting on it. INTRODUCTION Electric current is defined as the rate at which charge flows through a surface. As with all quantities defined as a rate‚ there

measurements. With this lab we had to understand how to analyze the data using measurement bounds. Theory: In this experiment we were to find the density of the wood we are measuring by using the method of upper bound and lower bound. Density is a physical property of matter. Every element and compound has its very own unique density associated with it. Density can be defined in a qualitative manner as the measure of the relative heaviness of objects with a constant volume or also as the amount per unit

heavier‚ it will sink. The force of buoyancy is important in many different areas‚ and especially in the making of ships. The surface area that is touching the water of the ship is very large‚ due to the shape of the hull‚ and that‚ beside the density of the ship‚ is what keeps the ship floating. An important example of how surface area affects buoyancy is when people float in the water. Everyone knows that it is much easier to stay afloat when we are lying on our backs than when we are in a standing

Yeung Results and Discussion Biology Lab 017 04/02/12 Marigold Lab The Purpose of this was to analyze how the Marigold plants grew under certain conditions. The Objective was to determine the amount of growth these plants went through by measuring the changes in the selected variables. The Variables that we selected were stem length‚ root length‚ the amount of leaves that grew on a plant and the overall size of the plant measured in height. For this experiment‚ we had three test groups‚

other forces acting on the drop‚ such as gravity‚ buoyant forces from the air‚ electrical forces‚ etc. In this experiment an electrical force of varying magnitude is introduced to change the motion of the falling drop by an ionization source. By measuring the velocity of the oil drop under different conditions the amount of charge on the drop may be determined. If the charge on the drop is an integer multiple of the fundamental unit of charge (the electron)‚ then one will be able to confirm the quantization

Cavite ( Use Arial 10) ABSTRTACT The objectives of this experiment were to determine the densities of some solids and liquids and to apply the rules of significant figures in computing laboratory data. For liquids‚ a dry‚ empty 100-ml graduated was weighed

obtaining an average density & boiling point for my liquid and comparing them with the known densities & boiling points of liquids in the CRC handbook of Chemistry & Physics. I will perform these experiments using three different measuring tools (graduated cylinder‚ burette & pipette) to evaluate the precision of each one. Results: Density 1‚ 2 & 3 calculated by using graduated cylinder to obtain volume. Density 4‚ 5 & 6 calculated by using volumetric pipette to obtain volume. Density 7‚ 8 & 9 calculated

Chemistry design: Fuel energy lab Research question: What is the energy density of cyclohexane‚ and how does it compare to the energy density of normal hexane? Variables: Independent variable – The independent variable in this experiment will be the type of fuel that will be used. This will be either Hexane or Cyclohexane. Each type will be given to us and labelled so it will be quite simple to control this variable. This cannot be measured using any apparatus so the lab assistant must be entrusted
