2 A torch uses four cells connected in series that provide a total potential difference of 6.0V. The power rating of the torch is 24W.
a What is the potential difference across one cell?
Tick one box.
• A 1.5V
B 3.0V -
C 12V
• D 24V

What is the magnitude of the resultant vector round your answer to the nearest tenth

Oxygen undergoes an isentropic expansion from 120 degree c and 280 kpa absolute to 140 kpa absolute. determine the final temperature of the oxygen and the amount of work per kg of o_2 produced in the process if it is adiabatic.

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?
