![]() ![]() (9) The nonzero electric field inside the wire is created by excess charges on the surface of the wire and in and on the mechanical battery. (8) At every location inside the wire the direction of the electric field is parallel to the wire. (7) The nonzero electric field inside the wire is created by the moving electrons in the wire. (6) Mobile electrons inside the wire push each other through the wire. Correctly label the diagram showing the drawings of laboratory equipment. (5) The magnitude of the electric field inside the wire is the same at all locations inside the wire. In the scientific method, what do we test with an experiment. ![]() (4) At location 3 the electric field points to the left. If an inductance is connected in one arm of bridge and resistances in the remaining three arms. (3) The electric field is zero at all locations inside the metal wire. EQUIPMENT AND SAFETY QUIZ Name: Due date: 1 This piece of equipment is called a: 3 If there is an accident in the laboratory, you must: 4 The Bunsen burner. (2) At location 3 inside the wire the electric field points to the right. (1) The electric field inside the wire varies in magnitude, depending on location. Which of the following statements about the circuit are true? List all that apply. In the circuit in Figure 18.98 a mechanical battery keeps a steady-state current running in a wire that has rather low electron mobility. Burette A graduated glass tube with a tap at one end, for delivering known volumes of a liquid, especially in titrations Electronic Balance Allows the user to quickly and accurately measure the mass of a substance to a level of accuracy impossible for traditional balances to achieve. pH sensor Scientific instrument that measures the hydrogen-ion activity in water-based solutions, indicating its acidity or alkalinity expressed as pH. Tongs Large pincers for grasping and lifting vessels of heat-resistant material used in high-temperature chemical reactions. Identify which activity should be avoided prior to starting an experiment in the microbiology laboratory. Safety Goggles Forms of protective eyewear that usually enclose or protect the area surrounding the eye in order to prevent particulates, water or chemicals from striking the eyes. This quiz and worksheet allow you to test the following skills: Reading comprehension - ensure that you draw the most important information from the related science lesson. It is used for holding a test tube in place when the tube is hot or should not be touched. Unlike the mercury-in-glass thermometer, the contents of an alcohol thermometer are less toxic and will evaporate quickly Test Tube Clamp Used to hold test tubes. Alcohol Thermometer Is an alternative to the mercury-in-glass thermometer and has similar functions. ![]()
