Is jumping a normal force? When we jump, the chemical energy in our muscles get converted to kinetic energy that exerts a force on the ground (that using Newton’s 3rd law), will trigger a reaction that will ‘push’ us up- and thus a jump. This resultant normal force = Mass x Distance of jump. Is […]
What is dependent and independent variable in regression?
What is dependent and independent variable in regression? The outcome variable is also called the response or dependent variable, and the risk factors and confounders are called the predictors, or explanatory or independent variables. In regression analysis, the dependent variable is denoted “Y” and the independent variables are denoted by “X”. How do you know […]
What happens to air pressure as altitude decreases quizlet?
What happens to air pressure as altitude decreases quizlet? As air pressure decreases altitude increases. As air pressure decreases so does density. What happens to air pressure and density as altitude increases? Altitude and Density The density of air decreases with height. There are two reasons: at higher altitudes, there is less air pushing down […]
Which element has a mass of 24?
Which element has a mass of 24? Chromium Why are lanthanides Coloured? Lanthanides or more precisely lanthanides ions are coloured mainly because of their partly filled f orbitals. This allows a certain wavelength from the visible region of the spectrum to be absorbed which leads to the formation of f-f transition. Is lanthanides are Colourless? […]

What is the difference between tables charts and graphs?
What is the difference between tables charts and graphs? Same, but Different Charts present information in the form of graphs, diagrams or tables. Graphs show the mathematical relationship between sets of data. Graphs are one type of chart, but not the only type of chart; in other words, all graphs are charts, but not all […]

Does specific heat depend on temperature?
Does specific heat depend on temperature? Therefore specific heat does not depend on temperature. What are the three factors affect the heat transfer that is necessary to change an object’s temperature? Experiments show that the transferred heat depends on three factors—the change in temperature, the mass of the system, and the substance and phase of […]
Is it better to get fit before playing sports or play sports to get fit?
Is it better to get fit before playing sports or play sports to get fit? Being fit is very important to overall health. However, when looking at sports performance the goals tend to be more specific and the level of training higher. Just by being fit does not necessarily mean that one is ready for […]
Is fracking good or bad?
Is fracking good or bad? In the U.S. alone, around 13 million metric tons of methane is released annually from natural gas wells alone. Fracking well sites are the source of a number of other air pollutants, which are less common than methane, but arguably more harmful to local populations. Where is fracking banned? Four […]
