So simply it to 120m/m for 120 minutes. So then you multiply 120x120 and that equals 14,400
Answer:
formation of gas bubbles at electrodes
deposition of metals at electrodes
changes in solution colour
electroplating
electrolysis
The work function is what we call the minimum energy that is required by an electron to leave the metal target in the photoelectric effect.
To find the impulse you multiply the mass by the change in velocity (impulse=mass×Δvelocity). So in this case, 3 kg × 12 m/s ("12" because the object went from zero m/s to 12 m/s).
The answer is 36 kg m/s
