How do you calculate water flow in a pipe? If the liquid is flowing through a pipe, the area is A = πr2, where r is the radius of the pipe. For a rectangle, the area is A = wh where w is the width, and h is the height. The flow rate can be […]
Which organ in the fish is most similar to the human respiratory system?
Which organ in the fish is most similar to the human respiratory system? The Alternative Lung In a way, the Fish Respiratory system is similar to the human respiratory system.

What is the main cause of food waste? What causes food loss and waste? Food loss occurs for many reasons, with some types of loss—such as spoilage—occurring at every stage of the production and supply chain. At the retail level, equipment malfunction (such as faulty cold storage), over-ordering, and culling of blemished produce can result […]
What are the two characteristics of an atom?
What are the two characteristics of an atom? Atoms are the smallest fraction of an element that can exist, and still show the characteristics of the element. Atoms themselves are composed essentially of electrons (1 negative charge), protons (1 positive charge), and neutrons (no charge). Why does each atom have specific properties? The difference in […]
What are the examples of positive feedback mechanism?
What are the examples of positive feedback mechanism? The release of oxytocin from the posterior pituitary gland during labor is an example of positive feedback mechanism. Oxytocin stimulates the muscle contractions that push the baby through the birth canal. The release of oxytocin result in stronger or augmented contractions during labor. What are examples of […]
At what speed do airbags deploy KMS?
At what speed do airbags deploy KMS? In reality, they’re rock hard, the airbag deployment speed can reach 300 km/h or more, and it all happens in a fraction of a second. They’re meant to prevent your head from striking the steering wheel, dash, windshield or side window. How long does it take an airbag […]
Do electric motors have horsepower?
Do electric motors have horsepower? Electric Motors An electric motor’s output is measured in kilowatts. Companies that build electric cars continue to talk about horsepower because consumers are still more familiar with that type of unit. The equation is as simple as hp = kW x 1.369, so a 100-kW motor produces 136 horsepower. Are […]
