2. Two point sources vibrating in phase create waves with a wavelength of 3.0 cm. The distance between a point on the third antinodal line to one of the sources is 68.0 cm. What is the
distance between the other source and the same point?

Panel bc in fig. p2.76 is semi-circular, with the 3 meter radius and horizontal straight edge through point b. compute (a) the hydrostatic force of the water on the panel, (b) its center of pressure, and (c) the moment of this force about point b. assume atmospheric pressure on the dry side of the panel

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?

What electron configurations do atoms usually achieve by sharing electrons to form covalent bonds?
