Beams of X-rays are targeted at a cancerous tumor from outside the body
Explanation:
Mechanical waves helps to treat cancer when beams of x-rays are targeted at a cancerous tumor from outside the body. These beams are energetic and ionizing. This will cause severe destruction of the cancerous cell.
- In cancer therapy, ionizing radiations are used to destroy cancerous cells in living organisms.
- Controlled doses of some forms of radiations are particularly known good medical procedures for curing cancer.
- Other options are not ways in which mechanical waves helps to treat cancer.

Answer:
buena suerte con las citas del futuro
Explanation:
Answer:
wavelength is 20.71 cm
Explanation:
given data
wave = 43.0 vibrations
time = 29 s
wave travels = 430 cm
time t2 = 14 s
to find out
wavelength
solution
we know here wavelength formula that is
wavelength = velocity / frequency .........................1
here frequency = 43 / 29 = 1.4827 Hz
and velocity = 430 / 14 = 30.71 cm/s
so here from equation 1 put all value
wavelength = velocity / frequency
wavelength = 30.71 / 1.4827
wavelength = 20.71 cm
so wavelength is 20.71 cm
Answer:
Ferromagnetism, physical phenomenon in which certain electrically uncharged materials strongly attract others. Two materials found in nature, lodestone (or magnetite, an oxide of iron, Fe3O4) and iron, have the ability to acquire such attractive powers, and they are often called natural ferromagnets.
