What is the moment of inertia of a uniform rod of mass m and length L? Moment of inertia of a uniform rod of mass m and length l is 712ml2 about a line perpendicular to the rod. What do you mean by parallel axis theorem? The mass properties of a rigid body that is […]

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. […]

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 […]

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 causes all the objects to move? When a force pushes or pulls the object, the object will move in the direction of the force. Force can make things move, change shape or change their speed. Some forces are direct and happen when two things touch (like a foot kicking a ball) or over a […]

What would happen if there was no sun for 24 hours? With no sunlight, photosynthesis would stop, but that would only kill some of the plants—there are some larger trees that can survive for decades without it. Within a few days, however, the temperatures would begin to drop, and any humans left on the planet’s […]

Are atoms mass? The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D)….Atomic Masses. (6) (7) (8) (9) What is the weight of one hydrogen atom? We now know that a hydrogen atom has a mass of 1.6735 […]

Can a stick be used as a machine? Wait, how is a stick a machine? It doesn’t take gas or electricity. Cooper: It is a machine! The way to figure it out is to think about whether it can transmit work. When you raise or lower a flag on a flagpole you are using a? […]
