The kilojoule content of foods depends on the amount of carbohydrates, fats and proteins present in the food, and the […]

How many different learning styles are there? Seven Learning Styles What is the Honey and Mumford Learning Style?

Can you walk to the North Pole? If you opt for an on-board expedition to the North Pole, your Arctic cruise will venture northbound through the Arctic Ocean seeking out whales in the Barents Sea (read our Arctic whales guide) before crossing the boundary of the North Pole, 90 degrees North, so you can literally […]

What does negative permeability mean? Negative magnetic permeability is when a material, in response to an imposed magnetic field, forms a magnetic dipole in the opposite direction to the imposed field. As regards PLASMA in a Magnetic Field the particles gyration results in a magnetic moment countering the external field. Therefore plasma is diamagnetic. Can […]

How do you find the power of a power property? This is an example of the product of powers property tells us that when you multiply powers with the same base you just have to add the exponents. This is called the power of a power property and says that to find a power of […]

Can a fact be disproven? A basic principle in science is that any law, theory, or otherwise can be disproven if new facts or evidence are presented. If it cannot be somehow disproven by an experiment, then it is not scientific. Take, for example, the Universal Law of Gravitation. What is a opinion statement? An […]

What are 3 examples of a chemical property? Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion. Iron, for example, combines with oxygen in the presence of water to form rust; chromium does not oxidize (Figure 2). Is size a chemical property? Any such characteristic of a material that […]

Is the phosphorus cycle fast? Phosphorus moves slowly from deposits on land and in sediments, to living organisms, and than much more slowly back into the soil and water sediment. The phosphorus cycle is the slowest one of the matter cycles that are described here. How does the phosphorus cycle start? Phosphorus moves in a […]

Why is US East Coast colder than West? Land has a lower heat capacity than oceans, and it also heats and cools faster than oceans. During the winter, land is much colder than the oceans. When the westerly winds blow over it, the air cools substantially. Thus, the East Coast experiences extreme cold weather during […]
