What is a sample space diagram? A sample space diagram is a maths table showing all the possible outcomes or results of events. It is used for probability questions. For example, the sample space of flipping a coin is heads or tails! What is possibility diagram? A Probability Space Diagram, or Sample Space Diagram, shows […]

What is the L quantum number? The angular quantum number (l) describes the shape of the orbital. Orbitals have shapes that are best described as spherical (l = 0), polar (l = 1), or cloverleaf (l = 2). They can even take on more complex shapes as the value of the angular quantum number becomes […]

Which device is used to break a circuit? switch Why is switch used in a circuit? The purpose of a switch in a series circuit is to make it easy to open or close the electrical circuit, turning the flow of electricity on or off. The purpose of the wires in a series circuit is […]

What is range of normal distribution? The area under each curve is one but the scaling of the X axis is different. Note, however, that the areas to the left of the dashed line are the same. The BMI distribution ranges from 11 to 47, while the standardized normal distribution, Z, ranges from -3 to […]

What happens if you triple the distance between two objects? If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power). What is the formula of gravitational force? The mathematical formula […]

Can tsunamis be stopped? Tsunamis could be stopped before they hit the coastline, a Welsh mathematician has proposed in a study of deep-ocean sound waves. Dr Usama Kadri, from Cardiff University’s School of Mathematics, has suggested that firing deep-ocean sound waves at an oncoming tsunami could save lives and reduce on-shore damage. What disaster will […]

Is it possible to cure myopia naturally? Myopia can be cured: MYTH Once this excessive eye growth has commenced, we can attempt to slow it down with myopia control treatments but we can’t stop the eyes from growing or reverse the excessive growth.
