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.

Answer:
answer d
Explanation:
methy group is in the second position while the double bond is in the third position
solution:
You need to find the frequency, and they have already given you the wavelength. And since you already know the speed of light, you can use formula (2) to answer this problem. Remember to convert the nano meters to meters because the speed of light is in meters. 
Answer:
-65.897°C.
Explanation:
- Adding solute to water causes depression of the boiling point.
- The depression in freezing point (ΔTf) can be calculated using the relation: <em>ΔTf = Kf.m,</em>
where, ΔTf is the depression in freezing point of chloroform solution.
Kf is the molal depression constant of chloroform (Kf = 4.70°C.kg/mol).
m is the molality of the solution (m = 0.51 m).
∴ ΔTf = Kf.m = (4.70°C.kg/mol)(0.51 m) = 2.397°C.
∴ The freezing point of the solution = (freezing point of chloroform) - ΔTf = (-63.5°C) - (2.397°C) = -65.897°C.
