Agirl tosses a stone into the air with an initial upward velocity of 8.00 meters/second8.00 meters/second and hears the splash when it hits the water 4.20 seconds4.20 seconds later. how deep is the water level in the well below where she tossed the stone

When using the scientist method, which step comes last?

Matter that emits no light at any wavelength is called

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
