Two balls with masses of 2.00 kg and 6.20 kg travel toward each other at speeds of 9.0 m/s and 4.00 m/s, respectively. If the balls have a head-on inelastic collision and the 2.00-kilogram ball recoils with a speed of 8.00 m/s, how much kinetic energy is lost in the collision

According to the phase diagram for water, how is the state of water determined? proceed up a vertical line at any given temperature read the phase at the intersection of any given temperature and pressure at a given pressure, proceed horizontally to the s-l or l-g line

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?

What quantity do units represent in value
