What is the approximate radius of a nitrogen nucleus that has seven protons and seven neutrons? a 1.2 × 10–15 m b 2.2 × 10–15 m c 2.7 × 10–15 m?

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.

the body's situation won't change the forces are equal opposit and on the same body

gravity

explanation:

iron would move it is magnetic there is a mag field around the current in the wire
