You performed an experiment in which you measured the amount of water leaking through different types of roofs. For one roof, you measured a volume
of 13.2 ounces. What is this measurement in Sl units? 1 lb = 16 oz; 1 kg = 2.2
lbs.
A. 0.375 kg
B. 0.78 kg
C. 31.2 kg
D. 5.8 kg

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

The star betelgeuse is about 600 light-years away. if it explodes tonight, a. we'll know because debris from the explosion will rain down on us from space.b. we'll know it immediately because it will be brighter than the full moon in the sky.c. we won't know about it until 600 years from now.d. none of the above.

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90
