What is a correlation matrix? A correlation matrix is simply a table which displays the correlation. The measure is best used in variables that demonstrate a linear relationship between each other. The fit of the data can be visually represented in a scatterplot. A correlation matrix consists of rows and columns that show the variables. […]

Which position is correct for a left turn? When making a left turn to and from a single-lane street, the proper position is to start and end your turn slightly to the left of the centre of the lane. At what distance should the warning triangle be placed if a vehicle breaks down on the […]

What is the relationship between the velocity and the acceleration of a particle undergoing simple harmonic motion? Velocity and Acceleration in Simple Harmonic Motion. A motion is said to be accelerated when its velocity keeps changing. But in simple harmonic motion, the particle performs the same motion again and again over a period of time. […]

How many 12×12 tiles do I need for 100 square feet? When you are planning your project and purchasing supplies it is important to be able to estimate approximately how many tiles you will need based on the size of the space. For a 100 square foot tile project, you will need to install a […]

What does the Zeroth Law of Thermodynamics concern? The Zeroth Law of Thermodynamics states that if two bodies are each in thermal equilibrium with some third body, then they are also in equilibrium with each other. This says in essence that the three bodies are all the same temperature. What does Zeroth law state? The […]

How much does it cost to make a 3D printer? Conventional 3D printer prices start at about $250 and go up and up! I was able to make one for about $87 (Prices may vary slightly based on where you live) with the same functionalities, resolution and a large build volume. Can you 3D print […]

What is the length of a pendulum with a period of 2 seconds? Using the SI recommended acceleration due to gravity of g0 = 9.80665 m/s2, the length of the string will be approximately 993.6 millimetres, i.e. less than a centimeter short of one metre everywhere on Earth. How do you calculate the period of […]
