Engineers must understand the thermal properties of materials to be able to predict the performance of any given material over its lifetime in a specific application. Engineers apply their understanding of the thermal properties of materials to the design of efficient heat transfer materials for better engines, spacecraft and electronic devices. They also examine the thermal properties of insulation to design more efficient buildings and homes. Engineers develop ways to minimize heat transfer from a motor to the surrounding environment. Often they find ways to insulate the motor to decrease the convective heat transfer from the motor. They design a refrigerator to keep heat out of the inside, as well as keep the refrigerator contents cool. hope this helped
Answer;
Bedrest with bathroom privileges
Explanation;
-Cardiac catheterization is a procedure used to diagnose and treat cardiovascular conditions. During cardiac catheterization, a long thin tube called a catheter is inserted in an artery or vein in the groin, neck or arm and threaded through the blood vessels to your heart.
-A child should not have a tub bath or go swimming for 5 days after the catheterization. After a child goes home from the hospital, they should be able to eat normally.
Answer:
The two abiotic conditions in the coral reef that contribute to the high biodiversity are:
- Temperature
- Sunlight
Whilst the abiotic factors are
- Plant and
- Bacteria
Explanation:
The coral reef which covers a space of 115,831 square miles (or 30 million hectares os space) is home to a rich diversity of aquatic life (plants and animals alike). Being the largest coral reef on earth a lot of attention is given to it to ensure that its health and functionality is preserved.
The above factors contribute immensely to the stability and operability of the great reef.
The coral reef abounds with many aquatic animals such as crabs, herbivorous fish, sea turtles, sea urchins etc Many of these feed off microscopic plants such as the phytoplankton (that is tiny plants) and microscopic animals referred to as zooplankton. The zooplankton in turn feed off microscopic plant, bacterioplankton and even other zooplankton.
It is easy to see that at the base of the food chain lies Phytoplankton and bacterioplankton. This group require sunlight to thrive.
The smaller herbivorous fish, crabs, sea turtles and urchins on the other hand, constitute food for larger animals such as sharks, Baracuda etc.
It is also important to note that these microscopic life (plant and animals) require a certain temperature to thrive. If the water body in these eco system were to exceed a certain temperature, it is highly doubtful that they would survive. The death the the plant and animal life at the base of the food chain will completely disrupt the entire biodiversity and may even lead to its extinction.

The answer is d.) relative dating
Answer:
We determined that if phosphorus is provided at the required level of 0.33%, the optimal ratio of calcium to phosphorus is 1.39:1 or 1.25:1 to maximise daily gain and gain-to-feed, respectively. To optimise bone ash, which is important for breeding sows, the ratio is 1.66:1,”
