According to archimedes' principle, the mass of a floating object equals the mass of the fluid displaced by the object. a 150-lbm swimmer is floating in a nearby pool; 95% of his or her body's volume is in the water while 5% of his or her body's volume is above water. determine the density of the swimmer's body. the density of water is 0.036lbm/in^3.

What can you increase the strength of an electromagnet by

How many neutrons does plutonium -196 with an atomic number of 78.

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
