A steel wrench feels 3N lighter in water.
a. what is the mass of the wrench?
b. how would your answer change if it took a more dense fluid to make the wrench feel 3N lighter?
a. ok so i know that density x volume=mass. The density of water is 1,000kg/m^3. That's about all I have. I don't really know where to go when i only have the weight of the steel and the density of water.
What are your thoughts?
