Two spheres are made of conducting material. Sphere #2 has twice the radius of Sphere #1 . What is the ratio of the capacitance of Sphere #2 to the capacitance of sphere #1?
a. 1, since all conducting spheres have the same capacitance. b. 2
c. 4
d. 8
e. A single sphere has no capacitance since a second concentric spherical shell is necessary to make a spherical capacitor. Thus, none of the answers above is correct.

A beaker of negligible heat capacity contains 456 g of ice at -25.0°C. A lab technician begins to supply heat to the container at the rate of 1000 J/min
How long after starting will the ice begin to melt, assuming all of the ice has the same temperature? The specific heat of ice is 2090 J/kg ? K and the latent heat of fusion of water is 33.5 × 104 J/kg.

What observational evidence supports the galactic fountain model (which describes how gas cycles between the disk of the galaxy and regions high above the disk)?
A) We have discovered a jet of ionized gas shooting out of the bulge of our galaxy. B) We have discovered that the entire galactic disk is being uniformly "rained on" by cool gas coming from the halo. C) We see hot gas high above the region of the disk near our solar system, along with cool gas that appears to be raining down from the halo. D) We have observed a lot of water molecules in the interstellar medium.
