Which of these best describes the difference between a closed and open system and the total energy in the system.
A) Since energy is always conserved, the total energy in both systems remains the same.
B) In a closed system the amount of energy remains the same. In an open system, energy is always released.
C) In a closed system the amount of energy remains the same. In an open system, energy is always absorbed.
D) In a closed system the amount of energy remains the same. In an open system, work is either done on or by the system changing the energy of the system.

Daughter element the new element produced along with a decay particle in a nuclear transmutation 2. half-life the substance that decays in a nuclear transmutation 3. parent element the change of one chemical element into another by nuclear decay or radioactive bombardment 4. transmutation the time required for the decay of one-half of the atoms in a sample of radioactive material

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?

What is the quantity which is measured by the area occupied below the velocity- time graph?
