Answer:
23 W/K
Explanation:
Entropy of water at 15°C is 224.5 J/kg/K.
Entropy of water at 15.2°C is approximately 227.4 J/kg/K (interpolated).
The increase in entropy is therefore:
227.4 J/kg/K − 224.5 J/kg/K = 2.9 J/kg/K.
So the rate of entropy generation is:
2.9 J/kg/K × 8 kg/s = 23.2 W/K
Rounded to two significant figures, the rate is 23 W/K.
One of the methods that are used to separate polymers, aluminium alloys, and steels from one another is the Gravitation Separation method.
One straightforward technique is to run the mixture through a magnet, which will keep the steel particles on the magnet and separate them from the polymer.
What is the Gravitation Separation method?
When it is practicable to separate two components using gravity, i.e., when the combination's constituent parts have different specific weights, gravity separation is a technique used in industry. The components can be in suspension or in a dry granular mixture.
Polymers, Steel and Aluminium alloys can be readily split apart. The technique depends on how the two components are combined. The approach used is gravitational density. Due to the significant difference in relative specific mass values between steel and polymers (which range from 1.0 to 1.5), it is possible to separate them using flotation in a liquid that is safe and has the right density.
Therefore, the Gravitation Separation method is used to separate polymers, aluminium alloys and steels.

Answer:
A. Identify the need, recognize limitations of current toothpaste containers, and then brainstorm ideas on how to improve the existing
Explanation:
To design an improved toothpaste container, we must identify the needs of the customer, one of the major need is to make the container attractive to the sight. This is the first thing that will prompt a customer to wanting to buy the product (The reflectance/appearance).
Then recognize the limitation of the current design, what needed change. This will help in determining what is needed to be included and what should be removed based on identified customers need.
The last step is to brainstorm ideas on how to improve the existing designs. Get ideas from other colleagues because there is a saying that two heads are better than one. This will help in coming to a reasonable conclusion on the new design after taking careful consideration of people's opinion.
Answer:
Yes once a room is not rented for a couple of hours in the night then it is perishable.
Answer:
The total load carried by the fiber will be "98%".
Explanation:
The given values are:
