详细解释: 以下为句子列表: 英文: After the ball leaves, the racquet mass center (balance point) moves at a slower speed, and this means a loss of its kinetic energy (kinetic energy = 1/2 mass times velocity squared). 中文: 球离开之后,球拍开始减速,球拍减速的过程就是能量释放的过程,释放能...
31, assuming that model errors are independently, identically, and normally distributed, the AIC can be written in terms of the number of free parameters, k, number of samples, \(\rho\), and the sum of squared residuals: $$AIC=2k+\rho {\text{ln}}\left(\frac{{\sum }_{j=1}^{\...
For the logisitic function 62 per cent are above Laplace's 5 per cent point. The percentage of samples above VB's 5 per cent points are 5.1 per cent for the squared function and 4.2 per cent for the logistic-map function. So, for this example, Laplace can tell you the posterior ...

(we are talking about classical mechanics here; in relativistic mechanics mass and energy can be exchanged). This is easily verified by applying a uniform translational velocity and checking that linear momentum is conserved. Higher order conditions, such as conservation of angular momentum, are ...
with |αN- |2 = 1 - 1αc-|2 the corresponding composition-dependent squared amplitude of the nitrogen character of the given conduction band state. Before deriving the electron effective mass in a GaNAs/GaAs QW structure, we first recall the calculation of the in-plane (parallel) effective...
1 slug is defined as a mass that accelerates by 1 foot per second squared when one pound-force is applied to it. It is about 14.59 kilograms. The solar mass is 1.9884×1030 kg Solar Mass The solar mass is used in astronomy to measure masses of astronomical objects such as stars, ...
During the last 20 years, geophysicists have developed great interest in using gravity gradient tensor signals to study bodies of anomalous density in the
The mass, below $10^{-55}$ kg, is proportional to $|\\vec V|$, while the group velocity exhibits a classic dBP dependence on the inverse of the frequency squared. For the CPT even classes ($k_{F}$ breaking tensor), the DRs display a massless but subluminal non-Maxwellian ...
An empty elevator of mass 2.7 \times 10^2 kg is pulled upward by a cable at an acceleration of 1.2 m/s. What is the tension in the cable? What would the tension be if the elevator were accelerating do A 2100...
