In physics, the letter μ is commonly used to represent the coefficient of friction and magnetic permeability. The coefficient of friction refers to the ratio of the frictional force (F) resisting the motion of two surfaces that are in contact to the normal force (N) that's pressing the two...
What if BR(h-->μμ)/BR(h-->ττ) does not equal m_μ^2/m_τ^2? Measurements of the Yukawa couplings of the recently discovered boson h to\nfermion pairs will provide a new arena for studying flavor physics. We analyze\... Aielet Efrati,Avital Dery,Yonit Hochberg,... 被引量:...
How far does light travel in a decade? The kilowatt hour is a unit for measuring ___. What does it mean when something is 4 or 5 light years away from us? What is the unit of sqrt(mu/epsilon)? How do we measure the speed of light?
Why does charge/area = current/(width*speed)? wo point charges, 1.0nC each, are located at points (17m, 0) and (-17m, 0). What is the potential at point (0, 2m)? What is the charge of positive 11 microCoulomb? How far from a 1.3 \muC point charge is the potential 12 V?
A few German mathematicians named Richard Courant, Kurt Friedrichs, and Hans Lewy derived a stability condition for explicit time-marching solutions for partial differential equations in their original paper titled On the partial differential equations o
However, even if RQ AGN does not launch relativistic jets, there is evidence for non-relativistic jets in some RQ AGN (see Section 2 below). We expect low-power, non-relativistic jets to interact with their environments much differently than high power, relativistic jets (e.g., [61,62,...
The same dose of vegetable protein does not produce the same effects [26]. Vegetable proteins can also cause a more significant decrease in blood pressure than animal proteins, according to the INTERMAP study on micronutrients and macronutrients in blood pressure [41]. 6.2. Regarding Micronutrients...
Measurements of the Yukawa couplings of the recently discovered boson h to fermion pairs will provide a new arena for studying flavor physics. We analyze the lessons that can be learned by measuring the h decay rates into the charged lepton pairs, τ +τ −, μ + μ − and τ ± μ...
In particular, it does not matter if the variations are of known or unknown origin, or fall under a deterministic or an indeterministic kind of physics. Continuing our detour into biology, the well-known Hardy–Weinberg equilibrium law in population genetics, which gives the relative frequencies ...
In physics, angular wave numbers are generally used rather than linear wave numbers. This means the wave number is measured in radians per unit time, not wave cycles. As a result, the wave number formula must be modified to take into account the differences in measurement and their relationshi...
