6. A car traveled on a flat road. The car's kinetic energy increased over time, while its potential energy remained constant. How did this change
affect the car's mechanical energy? *

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

The amount of potential energy possessed by an elevated object is equal to what?

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?
