Answer:
0.0804 m / h
Explanation:
r = 1 m, dr / dt = 8 cm/h = 0.08 m/h
the volume of sphere is given by
V = 4/3 x π x r^3
Differentiate with respect to r.
dV / dr = 4 / 3 x π x 3 r^2 x dr/dt
dV/dt = 4 x π x r^2 x dr/dt
dV/dt = 4 x 3.14 x 1 x 1 x 0.08
dv/dt = 0.0804 m / h
Imaging techniques that use wave behaviors are -
- sonography
- X-ray radiography
- CT scan
<h3>How can mechanical waves help in the treatment of cancer?</h3>
Ultrasound is used to improve absorption of a radioactive pellet by a tumor. The radioisotope in a radiopharmaceutical releases sound waves into surrounding cells. Beams of X-rays are targeted at a cancerous tumor from outside the body.
<h3>How can mechanical waves help the treatment of cancer?</h3>
HIFU is a cancer treatment that uses high-frequency sound waves. You have HIFU from a machine. The machine gives off the sound waves which deliver a strong beam to a specific part of a cancer. This heats and destroys the cancer cells.
HIFU can treat a single tumour or part of a large tumour. But it is not suitable for people with cancer that has spread to more than one place in their body.
