How can a magnet be used to find direction

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?

Multiply or divide to make this english distance conversion. 174 inches = feet (14.5, 58, 2,088, 23)

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same
