BRANLY IS GIVEN You have been selected to choose new sinks for bathrooms in a doctor's office. A slick sales
representative shows up with a sample of a flimsy feeling copper alloy sink. You are a little skeptical
the alloy provided by the slick sales representative has the requisite percentage of copper required
for antimicrobial properties. So, you check online with the EPA approved manufacturer and the
alloy produced by the company is 96.2% copper with a density of 8.89 g/cm3
The size of the cylindrical sample is 0.52 cm radius and a height of 7.00 cm. What is the volume of
the cylinder in cm3?
Volume of cylinder = TT r2h

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?

Consider each of the electric- and magnetic-field orientations given next. in each case, what is the direction of propagation of the wave? a)\vec ein the +xdirection,\vec bin the +ydirection. choose+ x direction- x direction+ y direction- y direction+ z direction- z direction b)\vec ein the -y direction,\vec bin the +x choose+ x direction- x direction+ y direction- y direction+ z direction- z direction c)\vec ein the +z direction,\vec bin the -x direction. choose+ x direction- x direction+ y direction- y direction+ z direction- z direction d)\vec ein the +y direction,\vec bin the -z direction. choose+ x direction- x direction+ y direction- y direction+ z direction- z direction

When can a theory be modified if a new type of technology allows for new observations that raise new questions? a-immediately, while the questions about the theory are being asked b-after new hypotheses related to the theory are tested in experiments c-only after the new observations disprove all parts of the theory d-while scientists begin to think about how the theory could improve
