Which describes a ferromagnetic material? Ferromagnetic materials, such as iron, are those that exhibit strong magnetic effects. The atoms in ferromagnetic materials act like small magnets (due to currents within the atoms) and can be aligned, usually in millimeter-sized regions called domains. What is meant by Ferrimagnetism? Ferrimagnetism, type of permanent magnetism that occurs in […]
What happens to the sound an object makes when the speed of vibrations decreases slow down?
What happens to the sound an object makes when the speed of vibrations decreases slow down? Explanation: because when the speed of vibrations decrease the pitch of sound becomes lower tone. How do air molecules enable sound to travel? How do air molecules enable sound to travel from a radio’s speaker to your ears? They […]
What happens to the temperature of the air around the cooling fins?
What happens to the temperature of the air around the cooling fins? Cooling fins rely on conduction to diffuse the heat away from what is being cooled. The fins are designed to increase the surface area with another liquid (air for example). Here the heat is transfered using convection, cooling the fins and warming the […]
Which macromolecule can we live without?
Which macromolecule can we live without? 1.) Nucleic acids: Nucleic acid is the most important major macromolecule. Nucleic acids are the most important, as without these no one would be around, where as without the other ones we might be able to evolve to survive. Without nucleic acids, none of us would be alive, as […]
Do seeds have life?
Do seeds have life? A seed is living. Although seeds are dormant (resting) their cells are still alive and performing typical cellular functions. Answer 3: They are just typically in a dormant state, which means they require very little of the resources necessary to stay alive, until they are in the appropriate conditions to grow. […]
What should you do before you form a hypothesis?
What should you do before you form a hypothesis? In order to form a hypothesis, you should take these steps: Collect as many observations about a topic or problem as you can. Evaluate these observations and look for possible causes of the problem. Create a list of possible explanations that you might want to explore. […]
Does higher density mean higher volume?
Does higher density mean higher volume? Density is determined by an object’s mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density. It is about how heavy something is compared to the same amount (volume) of water. Is density directly proportional […]
Why is there an energy shortage?
Why is there an energy shortage? Overconsumption. The energy crisis is a result of many different strains on our natural resources, not just one. There is a strain on fossil fuels such as oil, gas, and coal due to overconsumption – which then, in turn, can put a strain on our water and oxygen resources […]
What are some of the typical problems that a school psychologist might encounter?
What are some of the typical problems that a school psychologist might encounter? What are some of the typical problems that a school psychologists might encounter? Family problems, learning disorder, learning to read, write or do math. What is the difference between school psychology and school counseling? School counselors focus more on improving mental health […]
Why is the heart called a double pump?
Why is the heart called a double pump? Your heart is a single organ, but it acts as a double pump. The first pump carries oxygen-poor blood to your lungs, where it unloads carbon dioxide and picks up oxygen. It then delivers oxygen-rich blood back to your heart. The second pump delivers oxygen-rich blood to […]
