How can mechanical waves help in the treatment of cancer?
Andreas93 [3]

Mechanical waves can help in the treatment of cancer due to heat generated by the high frequency waves.

<h3>What is mechanical wave?</h3>

A mechanical wave is a wave that requires material medium for its propagation, example include;

  • water waves,
  • sound waves, and
  • seismic waves.

<h3> Mechanical waves in treatment of cancers</h3>

Sound wave in example of mechanical wave because it requires material medium for its propagation.

High-frequency sound waves (HIFU) is used in the  treatment  of cancer because the strong beam generates heat which is directed to a specific part of a cancer.

The heat generated destroys the cancer cells.

Thus, mechanical waves can help in the treatment of cancer due to heat generated by the high frequency waves.

Q. How many molecules of H2O can be produced from reactants in container below?

A. 3 molecule of molecules H2O will be produced from reactants in container.

<em><u>Explanation</u><u>:</u></em>

There are seven molecules of H2 and three molecule of O2 are there in the container Q, 6 molecules of H2 will react with 3 molecules of O2 to produce 3 molecules of H2O. One molecule of Hydrogen will not take part in reaction and will be present in container Q after then reaction, and the mass in overall reaction is conserved!
