15 мар. 2018 г. · In Einstein's formula E=mc2, c is the speed of light. However the speed of light is not a unique number. It can be expressed in kilometres per ... |
15 мар. 2013 г. · The value of c isn't physical - it is an arbitrary conversion factor between the unit of time and length, in arbitrary man-made SI units. |
9 авг. 2019 г. · “Setting c=1” is a convenient shorthand in several unit systems including Planck units, to try to normalize the units of energy and mass (say) ... |
7 нояб. 2016 г. · c is inversely proportional to how easy it is to magnetise free space, and inversely proportional to how difficult it is to create an electric field in free ... |
21 янв. 2013 г. · Setting c=1 shows the true symmetry between space and time. Some theoretical physicist like to do that just to avoid constants while ... |
15 февр. 2016 г. · You can also calculate $ c=sqrt (E/m), from Special Relativity, but now you must measure the energy derived from a change in mass. Both of these ... |
25 мая 2022 г. · From the equation of E=mc2, where E is the energy, m is the mass and c is the speed of light, so from that we can get c=√Em, again from the ... |
18 дек. 2016 г. · There is a theoretical "prove" that c is constant, though it could be considered "weak". Let me explain. |
22 янв. 2012 г. · The reason c is important is not because it is the speed of light. It's important because it is a universal conversion factor between time and distance. |
