Once more a mysterious metallic sphere has come to ground in Kansas, and the citizens of Hoxie have called in your consulting firm for help in identifying the material in the meteorite, which appears to have magnetic properties. You rush to Hoxie to investigate, but unfortunately your Hall probe device fails, leaving you with only a strong bar magnet and a sensitive compass. Nevertheless, you manage to identify samples from three parts of the meteorite as being diamagnetic, paramagnetic, and ferromagnetic. For your later report, you jot down the measurements and observations you made to establish the identifications. Briefly summarize these for the:

A. Diamagnet
B. Paramagnet
C. Ferromagnet

Give an example in which the electrical energy changes to light energy

If you wanted to move an electron from the positive to the negative terminal of the battery, how much work w would you need to do on the electron? enter your answer numerically in joules.

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
