What is the difference between the meaning of measurement and the value of measurement in physics? why is distance usually on the bertical axis even if the distance is the independent variable? What principle can a physicist use to calculate the distance of the closest approach? a) ...
The center of mass of a system is the unique point in which the sum of all parts of the system is zero. This is basically the average position in which this unique point is located.Answer and Explanation: The center of mass is defined as the average position of all the parts of a gi...
Conservation is assumed to be born in the phase, just as momentum is for instance. In other words, all known phenomena in physics are deterministic, classical and real, in the sense that information does propagate locally and experiments conducted statistically do hide latent variables....
However, I don't see why we can use R here rather than the distance from the center of the pulley to the mass. Isn't the moment of inertia = mr^2, where r is the distance the center of the pulley to the position of m1? When we use ##\Sigma m_i r_i^2## to find an ...
Let’s consider a recent example of use and misuse of a P-value. When physicists discovered the Higgs boson, they said the strength of the data supporting it is 5-sigma, meaning a P-value of 3 × 10E−7 or about 1 in 3.5 million. Contrary to what you may think, this is not ...

The same r as in the polar coordinates. It is the distance of point (X, Y) to the origin, where z = X + i Y. Btw, I used capital letters to distinguish them from the "x" in your equation which is actually phi. Taking it one step further, you ha...
Uniform Distribution has a constant probability. It is important to practice examples of uniform distribution after learning it’s formulas. The Uniform distribution is denoted by X U (a,b).
