A beaker of water sits in the sun until it reaches an equilibrium temperature of 30 degrees C. The beaker is made of 100g of aluminum and contains 180g of water. In an attempt to cool this system, 100g of ice at 0 degrees C is added to the water.
A) determine the final temperature. If Tf = 0 degree C, determine how much ice remains.
B) Repeat this for 50g of ice.
Consider a half-infinite hollow cylindrical shell (that is, one that extends to infinity in one direction) with uniform surface charge density. Show that at all points in the circular end face, the elec- tric field is parallel to the cylinder's ax..
