3. If a metal wire carries a current of 80.0 mA, how long does it take for 3.00 x 1040 electrons to pass a given cross-sectional area of the wire?

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

i believe the answer is a hope it and is correct
