According to Kepler's third law,the orbital period T of a planet is related to the radius R of its 相关知识点: 试题来源: 解析 即T ^ 2=t ^ 2 * R ^ 3 / r ^ 3 (R / r=4.97,故R ^ 3 / r ^ 3 =122.763473) 两边开方:T=t * (R ^ 3 / r ^ 3) ^ 0.5=11.07986791 (years...
Third law of Kepler – the law of periods: You can obtain the simplified form of the third law of Kepler by comparing the centripetal force to the gravitational force (see gravitational force calculator). The full corresponding formula states that the orbital period of a satellite TT is given...
Then, a mechanical long-period grating is applied on the two-mode fiber to convert the fundamental mode to the LP1,1LP1,1 mode. Then, a rotator is used to adjust the intensity orientation of the LP1,1LP1,1 mode to the pressure applying slabs. When the orientation angle is 45∘45∘...
Especially when the phase singularity approaches the geometric center of the beam, Equation (2) degenerates into Equation (1). Based on the off-axis single vortex beam, the off-axis double vortex beam can be regarded as the superposition of two off-axis single vortex beams [17]. Accordingly...
