Calculate the energy and momentum of a photon of wavelength 710 nm. What is the mass of a photon? What are the frequency, wavelength, and momentum of a photon whose energy equals the rest mass energy of an electron? An electron has the same energy as a photon of green light (530 nm)...
The change in linear momentum of an object is equal to the change in the linear momenta of a moving object at any two points in space. Mathematically, it is expressed as: Δp=pf−pi Where, pi and pf are the initial and final linear momenta of an object....
For over 30 years, extensive research has found corroborating evidence that past winners continue to yield higher returns than past losers. This momentum effect is robust across various asset classes and across the globe and presents perhaps the most pervasive contradiction of the efficient market hypo...
that is not the case. Honey is characterized by its thick consistency, which is a direct result of its very strong intermolecular forces. These intermolecular forces give rise to high internal frictions within the layers of the fluid (honey), which makes the fluid resist the motion of the ...
Undoubtedly the most famous equation ever written is E=mc². This equation says that energy is equal to the rest mass of the object times the speed of light squared (c is universally accepted as the speed of light). What is this equation actually telling us? Mathematically, since the spe...
This equation can lead to the drawing of a trendline with varying periods used in the calculation. Understanding Market Momentum Positive momentum can indicate a potential bullish trend while negative momentum can indicate a bearish trend. Broadly, momentum can be measured across both asset classes an...
As shown from the above equation,CAPM involves the risk-free rateof an investment like a U.S. Treasury bond, an asset’s beta, and the expected return of the market. It is important to ensure that these values are all taken from the same time period. Here we use a 10-y...
The construction of a relativistic thermodynamics theory is still controversial after more than 110 years. To the date there is no agreement on which set of relativistic transformations of thermodynamic quantities is the correct one, or if the problem ev
Example 1:Calculate the distance necessary to stop a carmoving at 90 km/h on a horizontal wet asphalt concrete (coefficient of friction μ = 0.4) if the driver perception time is 0.5 s and reaction time is 0.7 s. Example 2:Calculate the initial speed of the carmoving on a wet ...
