Ice or compacted snow sublimes to a saturated vapor in cold climates. Estimate the rate at which ice will sublime per unit area on an iceberg if the ice is -30ºC and the air is - 10ºC. Assume a convective heat transfer coefficient of 20 W/m^2?K.
What will be an ideal response?
Potential of Point-Charges: Three point charges are placed at the following points in a horizontal x-y plane: +4.0 ?C is at (0.00 m, 0.50 m), + 1.0 ?C is at 0.20 m, 0.00 m), and -5.0 × ?C is at (0.20 m, 0.50 m). Calculate the electrical potential (relative to infinity) at the origin due to these three point charges. (k = 1/4??0 = 9.0 × 109 N ? m2/C2)

Time Dilation: A pion is an unstable particle that has a mean lifetime of 2.55 × 10-8 s. This is the time interval between its creation in a nuclear process and its extinction into decay products, as measured in a frame of reference at rest with respect to the pion. An average pion is traveling at 0.230c relative to Earth. How far does it travel in its lifetime, relative to Earth?
A. 2.07 m B. 1.81 m C. 2.23 m D. 3.22 m E. 3.50 m
