for Review test4 Chapter 22 chapters 22, 24, 25, and 26 Like charges repel and unlike charges attract. Electric force between two charges is proportional to the product of the charges divided by the square of the distance between the two charges. Gravitational force is much weaker than the electric force. What are the three modes for electric charging? What is polarization of charge? Which force binds atoms together to form molecules? A. gravitational B. nuclear C. electrical D. centripetal E. Neither of these The fundamental force underlying all chemical reactions is A. gravitational. B. nuclear. C. centripetal. D. electrical. E. none of these. In an electrically neutral atom the number of protons in the nucleus is equal to the number of A. electrons that surround the nucleus. B. neutrons in the nucleus. C. both of these. C. neither of these. A positive ion has more A. electrons than neutrons. B. electrons than protons. C. protons than electrons. D. protons than neutrons. E. neutrons than protons. ___ Strip electrons from an atom and the atom becomes a A. positive ion. B. negative ion. C. different element. D. proton. E. electron ______________ A main difference between gravitational and electric forces is that electrical forces A. attract. B. repel or attract. C. obey the inverse-square law. D. act over shorter distances. E. are weaker. The electrical force between charges is strongest when the charges are A. close together. B. far apart. C. the electric force is constant everywhere. D. not enough information. E. need more info. The electrical force on a 2-C charge is 60 N. What is the value of the electric field at the place where the charge is located? A. 20 N/C B. 30 N/C C. 60 N/C D. 120 N/C E. 240 N/C Two charged particles repel each other with a force F. If the charge of one of the particles is doubled and the distance between them is also doubled, then the force will be A. F B. 2F C. F/2 D. F/4 E. None of these The electric field inside an uncharged metal ball is zero. If the ball is negatively charged, the electric field inside the ball is then A. Less than zero B. Zero C. Greater than zero Two charged particles held close to each other are released. As they move, the force on each particle increases. Therefore, the particles have A. The same sign B. Opposite signs C. Not enough information Chapter 24 What is the source of magnetism? Like poles attract and unlike poles repel. What is the direction of the magnetic field between the north and south poles? What a is domain? How can a magnet attract a piece of iron that is not magnetized? What is the effect of a magnet on a moving charge? Do electric current produce magnetic fields? Do current carrying wires experience magnetic forces when they are placed in a magnetic field? Review questions What I the source of magnetic force? In what way are magnetic poles different than electric charges? What two kinds of rotational motion are exhibited by electrons in an atom? What is the difference between an umagnetized iron nail and a magnetized iron nail? What effect does the Earth's magnetic field have on the intensity of Cosmic rays striking Earth? Review questions continued Why will dropping an iron magnet on a hard floor make it a weaker magnet? What is meant by magnetic declination? What is the cause of aurora borealis (northern lights)? Chapter 25 In 1831, Michael Faraday discovered how to use magnetism to generate electric currents. This is called magnetic induction. There are three ways a current (voltage) can be induced in a loop of wire: Moving the loop near a magnet Moving a magnet near the loop Changing a current in a nearby loop Faraday's Law The magnitude of the induced voltage in a coil depends on the number of turns of loops and the rate at which magnetic field strength changes the area of the loops. Transformers V V P= S Np Ns Example: Vp = 100 V; Np = 100; Ns = 1000 100 V VS = 100 1000 Vs = 1000 V Chapter 26 How is an electromagnetic wave generated? Moving charge is an electr...
