Time of flight is the total time taken to complete the projectile motion, it will be double the time taken to reach the maximum height.
1 dzień temu · Hubble's law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. In other words, the farther they are, the faster they are moving away from Earth. The velocity of the galaxies has been determined by their redshift, a shift of the light they emit toward the red end of the visible ...
1 dzień temu · Physics is the natural science of matter, involving the study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. A scientist who specializes in the field of physics is called a physicist.
2 dni temu · Instead, optical clocks supported by optical time-transfer methods are needed for those experiments. Free-space optical time transfer is a technique that uses frequency combs—trains of equally spaced ultrashort pulses—to compare time between optical clocks at the femtosecond level across hundreds of kilometers of air.
3 dni temu · Coulomb’s law, mathematical description of the electric force between charged objects. Formulated by the 18th-century French physicist Charles-Augustin de Coulomb, it is analogous to Isaac Newton’s law of gravity. Learn more about Coulomb’s law in this article.
2 dni temu · Wavelength λ can be measured between any two corresponding points on a waveform. Animation of two waves, the green wave moves to the right while blue wave moves to the left, the net red wave amplitude at each point is the sum of the amplitudes of the individual waves. Note that f(x, t) + g(x, t) = u(x, t). in the direction in space.
3 dni temu · We analyze data on \(B\rightarrow K\mu ^+\mu ^-\) and \(B\rightarrow K^*\mu ^+\mu ^-\) decays in the whole dilepton invariant mass spectrum with the aim of disentangling short- vs. long-distance contributions. The sizable long-distance amplitudes from \(c \overline{c}\) narrow resonances are taken into account by employing a dispersive approach. For each available \(q^2=m^2_{\mu \mu }\) bin ...
