What are the difference between positive and negative slope? A higher positive slope means a steeper upward tilt to the line, while a smaller positive slope means a flatter upward tilt to the line. A negative slope that is larger in absolute value (that is, more negative) means a steeper downward tilt to the line. […]

Why does a ray of light bend when travel from one medium to another? A ray of light bends while going from one medium to another because of the phenomena of refraction. When the ray of light travels from one medium to another as the velocity of the light ray will either increase or decrease […]

How do you slow down a sled? To slow down or stop on flat terrain, put both feet out into the snow. In steep terrain we recommend sitting towards the back of the sled, putting both feet flat on the ground and holding on tight to the front of the toboggan. If you need to […]

What is an example of natural disaster limiting population growth? A strong thunderstorm destroys many of the nests of a bird population. A month of colder air in the spring delays the growth of plants that provide food for a deer population. What are the limiting factors to population growth? In the natural world, limiting […]

What do you mean by kilo joule? A kilojoule (or Calorie) is a unit of energy. In Australia, we use kilojoules (kJ) to measure how much energy people get from consuming a food or drink. 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? Learning styles were developed by Peter Honey and Alan Mumford, based upon the work of Kolb, and they identified four distinct learning styles or preferences: Activist, Theorist; Pragmatist and Reflector. understand their learning style. seek out opportunities […]

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 […]
