To calculate the volume of a rectangular, we have to multiply the value of height, length and width.
8x5x4 = 160 cm ^3
Mechanical waves are those waves that require a material medium for propagation.
<h3>What are mechanical waves?</h3>
Generally, we define a wave as a disturbance along a medium which transfers energy. It then follows that waves move energy from one point to another.
Waves can be classified as;
- Mechanical waves
- Electromagnetic waves
Mechanical waves are those waves that require a material medium for propagation such as sound, and waves on a strings.

In a hydrolysis reaction between a strong acid and a weak base, the salt formed will have a pH less than 7. By virtue of this phenomenon between <span>weak bases and strong acids</span>, the anion of the strong acid will fail to attract the hydrogen ion<span>, while the cation from the weak base will donate a </span>proton<span> to the water forming a hydronium ion</span><span>.

As we know that power is defined as rate of work done
so we will have
so in order to increase the power as per above formula we know that either we need to increase the work or we need to decrease the time to complete that work
So here the correct answer will be
increase the work being done or decrease the time in which the work is completed.
