10. Which statement is true about the Milky Way Galaxy? It is a spiral galaxy. It contains no more than 100 million stars. New stars are not being created in It.

When Rutherford ran his gold foil experiment, he expected to see results like those in the Plum Pudding Atom simulation. Instead, his experimental results were closer to those seen in the Rutherford Atom simulation. Why can't the plum pudding model of the atom explain Rutherford's experimental results? Since some alpha particles were deflected, the atom must contain a small region with a strong electric charge. Since most of the alpha particles were not deflected, the atom's positive charges must be spread thinly across a large region. Since some of the alpha particles were deflected, the atom's negative charges must not be attracted to the alpha particles. Since most of the alpha particles were not deflected, the atom's negative charges must exist in a thin cloud around the atom.

Which of these is a random error? Using a balance scale or a digital scale Physical effects not considered in the analysis Miss-calibrated instrument A physical defect in the instrument

59. Conduction is A) the direct transmission iof energy without the need for a medium of transfer. B) the transfer of heat via bulk motion of the medium. C) the transfer of heat by electron and atomic collisions. D) the only way to transfer heat from a colder object to a warmer ones. 60. Convection is A) the direct transmission of energy without the need for a medium of transfer. B) the transfer of heat via bulk motion of the medium. C) the transfer of heat by electron and atomic collisions. D) the only way to transfer heat from a colder object to a warmer ones. 58. When you touch the metal handle of the room -temperature stainless-steel frying pan, it feels cool to your touch. When you grab a room-temperature sauce pan by its plastic handle, A) it feels cooler than the metal handle because plastic conducts heat better than the metallic steel. B) it feels warmer than the metal handle because the steel handle conducts heat better than the plastic. C) it doesn't feel cooler or warmer than the steel. Why would it? Both handles are at room temperature! 2 points 2 points 2 points
