A 88-kg sample of liquid water is cooled from 0 degrees Celsius to -43 degrees Celsius. It freezes in the process. How much heat is liberated? For water Lf=334 kJ/kg and Lv=2257 kJ/kg. The specific heat capacity of ice is 2.05 kJ/kg x degrees Celsius.

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.)

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
