Suppose the maximum safe average intensity of microwaves for human exposure is taken to be 1.50 w/m2. if a radar unit leaks 10.0 w of microwaves (other than those sent by its antenna) uniformly in all directions, how far away must you be to be exposed to an average intensity considered to be safe? assume that the power spreads uniformly over the area of a sphere with no complications from absorption or reflection.

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
