What if there is two medians? If there is an even number of numbers add the two middles and divide by 2. The result will be the median. How do you get rid of mean? How to Find the Mean. The mean is the average of the numbers. It is easy to calculate: add up […]
How do you read contour intervals?
How do you read contour intervals? How To Read Contour Lines Index lines are the thickest contour lines and are usually labeled with a number at one point along the line. Intermediate lines are the thinner, more common, lines between the index lines. Supplementary lines appear as dotted lines, indicating flatter terrain. What is another […]
What happens when water cools below 4?
What happens when water cools below 4? Right when the water freezes to ice, the ice becomes significantly less dense than the water and continues to float on the lake’s surface. Below 4° Celsius, water becomes less dense as it gets colder, causing water about to freeze to float to the top. What happens when […]
What two forces are balanced in any star?
What two forces are balanced in any star? Gravitational forces act to contract the star. Fusion reactions and heat convection act to expand the star. The two forces are balanced and the star remains stable in size and reactions. What does it mean that the energy in the sun is balanced? What does it mean […]
How do you solve accuracy and precision?
How do you solve accuracy and precision? Find the difference (subtract) between the accepted value and the experimental value, then divide by the accepted value. To determine if a value is precise find the average of your data, then subtract each measurement from it. This gives you a table of deviations. Then average the deviations. […]
Will a 220v bulb work on 120V?
Why there is a need for scientific knowledge in education?
Why there is a need for scientific knowledge in education? Problem-solving and critical thinking are two of the most important skills students learn in school. In this way, science is one of the most important subjects students study, because it gives them the critical thinking skills they need in every subject. What is the impact […]
Do electrons know they being observed?
Do electrons know they being observed? This process is sometimes referred to as decoherence. We also see phrases such as “wavefunction collapse”. By virtue of such an interaction of a quantum system with a classical measurement device, one could quite misleadingly assert that the electron “knows” it is being observed. It doesn’t. Why do wave […]
