This type of solution is characterized by water molecules moving into and out of the cell at the same rate A long coil of wire with many loops used to create a large magnetic field Slide 14 What is: a solenoid What is: a solenoid Slide 15 A device that converts electric energy to rotational kinetic energy Slide 16 What is: an electric motor What is: an electric motor Slide 17 Maintaining conditions suitable for survival A device that is used to detect very small currents Slide 18 What is: a galvanometer What is: a galvanometer Slide 19 The process in which current is generated in a wire due to the relative motion between the wire and the magnetic field Slide 20 What is: EM induction What is: EM induction Slide 21 Of the following diagrams, the one most similar to what you would expect to see inside the iron of a solenoid Slide 22 What is: What is: Slide 23 How many electrons pass through a circuit in 1 second? Of the following, the electromagnet that would produce the magnetic field with the maximum strength: one with 10 loops, 20 loops, or 40 loops Slide 24 What is: the one with 40 loops What is: the one with 40 loops Slide 25 One of two ways to increase the magnitude of the magnetic field in an electromagnet Slide 26 What is: increase the current or the number of loops What is: increase the current or the number of loops Slide 27 Of the following materials, the one that should be used in addition to a spool of wire to create an electromagnet: glass rod, iron rod, or wood rod Slide 28 What is: the iron rod What is: the iron rod Slide 29 What happens to the electromagnet when you reverse the direction of current flow Slide 30 What is: the poles are reversed What is: the poles are reversed Slide 31 The part of your hand that indicates the direction of the current when using the right-hand rule Slide 32 What is: your thumb What is: your thumb Slide 33 The direction of the magnetic field above the following wire if the current is flowing to the right Slide 34 What is: out of the page or toward you What is: out of the page or toward you Slide 35 What is the attractive force between water molecules called? Strands of DNA; contain directions for making protein The direction of the magnetic field inside the following loop if the arrow indicates the direction of the current Slide 36 What is: out of the page or toward you What is: out of the page or toward you Slide 37 The direction of the magnetic field to the left of the following wire if current is flowing upward Slide 38 What is: out of the page or toward you What is: out of the page or toward you Slide 39 The direction of current if the direction of the magnetic field is clockwise Slide 40 What is: into the page or away from you What is: into the page or away from you Slide 41 The relationship between the number of turns on the primary coil compared to the number of turns on the secondary coil of a step- down transformer Slide 42 What is: primary is greater than secondary What is: primary is greater than secondary Slide 43 A transformer can step this up but in no way can step up this Slide 44 What is: voltage then power or energy What is: voltage then power or energy Slide 45 How power delivered to the secondary circuit relates to the power delivered to the primary circuit of a transformer Slide 46 What is: they are equal to one another What is: they are equal to one another Slide 47 A step-up transformer does this to voltage and this to current Slide 48 What is: increase voltage and decrease current What is: increase voltage and decrease current Slide 49 The voltage across the secondary circuit of a step- up transformer that has 250 turns on its primary coil, 7000 turns on its secondary coil, and a primary voltage of 18.0 V Slide 50 What is: 504 V What is: 504 V Slide 51 FinalJeopardy Slide 52 Transformers Slide 53 The current in the primary circuit of a step-up transformer if the primary coil has 40 turns, the secondary coil has 1200 turns, and the current in the secondary circuit is 1.50 A Slide 54 What is: 45.0 A What is: 45.0 A Slide 55 DailyDouble!
