Visit this density simulation at the link provided and click the "turn fluid into water" button to adjust the density of liquid in the beaker to 1.00 g/mL. Use the water displacement approach to measure the mass and volume of the unknown material (select the green block with question marks). What are the mass and volume of the material?

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

we need to know the time interval during which the force acts. impulse of force = momentum change

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
