This is a <span>John Kanzius Research. </span>Radiofrequency Ablation (RFA) which is a type of Electrical Energy is used to treat cancer. It u<span>ses heat made by </span>radio waves<span> to kill </span>cancer<span> cells. Ablation means destroying completely. The method is putting RFA  a probe (electrode) that goes through the skin into the tumour. A</span> CT scan is needed so to check that the probe is in exactly the right place. An electrode in the probe creates radiofrequency energy to produce heat and kill the cancer cells.

Destroying cancer cells requires a lot of energy.

High-frequency waves have high energy.

--

The destruction of cancer cells requires a lot of energy, so high-frequency radio waves can be used in this technology because they have high energy.

Select the correct location on the image.<br> Identify the magnetic north pole of Earth’s magnet.
OverLord2011 [107]

The magnetic north pole of the earth's magnet is in the geographic south pole.

  • There are two magnetic and geographic poles each, north and south
  • The two geographic poles are the locations where the earth's axis of rotation passes through which is imaginary
  • The magnetic north and south poles are not the same as the geographic north and south poles
  • In a compass, the needle points to the magnetic north pole
  • By convention, the magnetic north pole corresponds to the geographic south pole
  • The magnetic south pole corresponds to the geographic north pole
  • The magnetic field lines of a magnet start from the magnetic north pole and end at the magnetic south pole

The magnetic north pole of the earth's magnet is the geographic south pole.
