Question 12 The electricity from a household outlet can be dangerous because It uses alternating current 120 Volts can be stronger than nerve signals O It can source enough current to cause harm O It uses direct current Question 13 A cell phone wrapped in metal foil is observed to not be able to get a signal and ring when ca Which concept that best explains why this happens?
Question 5 8.75 pts Which force is involved in holding atoms together? O gravity the strong force electrostatics magnetism D Question 6 8.75 pts A transformer is used to convert from one voltage to another. Which concept best describes how this is done? Ohm's law Cole's law Wien's law Faraday's law
Question 7 8.75 pts Can a magnetic field cause a current in a coil of wire? yes, but only if the field is changing yes, any magnetic field can create a current no, it is currents that make magnetic fields Ono, magnetism and electrostatics are not related Question 8 8.75 pts Based on the screen this test is displayed on, if a charged particle was moving left to right through a magnetic field pointed up,^ the force on the particle...
A moving charge or current can produce a magnetic field. O True O False
A moving charge or current can produce a magnetic field. True False
Moving charges will produce a local magnetic field, but the reverse is also true a changing magnetic field will similarly induce charges to move (ie. produce current). Consider a magnet moving into a coil of wire: A spinal coil of wire with many closely-spaced tums this is called a solenoid is connected to a micro-ammeter as shown in the diagram above. As the magnet moves into the coil, any induced current will be measured by the micro-ammeter. Question On the...
