Arigid tank with a volume of 1.0 m3 initially contains h2o at 0.07 mpa and 100°c. it is filled from a steam line at 0.70 mpa and 200°c. the tank is filled to a level of 90 % liquid on a volume basis. the tank is maintained at 100°c during the process. evaluate the required heat transfer (kj) to maintain the tank at the constant temperature.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.

explanation:

force tends to be low and long diustance masses are high
