Answer:
Explanation:
information we have:
mass:
lenght:
frequency:
time:
and from the information we have we can calculate the angular velocity . which is defined as
----------------------------
Now, to calculate the torque
We use the formula
where is the moment of inertia and
is the angular acceleration
moment of inertia of a uniform rod about the end of it:
substituting known values:
for the torque we also need the acceleration which is defined as:
susbtituting known values:
and finally we substitute and
into the torque equation

The characterization of paraffin/ultrasonic-treated diatomite for use as phase change material in thermal energy storage of buildings and it provides the highest surface area with least to no structural degradation.
<h3>What are the characterization of paraffin/ultrasonic-treated diatomite?</h3>- Paraffin/ultrasonic-treated diatomite is used as a phase change material or PCM in thermal energy storage of buildings.
- The diatomite is treated multiple times in ultrasonic sound for approximately sixty minutes or DA-60.
- This is done to achieve the optimum condition to improve the surface area.
- When the surface area reaches the highest, the structural degradation reaches minimum.
- 59°C is the melting point of the DA-60 composite phase change material. The latent heat of the same is 45.90
.
- A stable PCM will have proper thermal reliability which is attained through thermal cycling test of 500 cycles.
