Tags Lifetime Stellar In summary, the equation for calculating the lifetime of a star is k*m/l, where k is a constant, m is the mass of the star, and l is the star's luminosity. Using this equation, it can be determined that a star with 24 solar masses and 300,000 times the...
What is the formula for velocity? Vector Form of Speed: The quantities such as mass, speed, electric current, velocity, acceleration, etc. are classified into two categories. These categories are vectors and scalars. The vectors are such type of quantities which are defined completely if we kno...
In this article, we will talk about agile processes to build your startup iteratively. The most important formula for success in a startup is by ensuring that you’re improving your product/service consistently to provide great value to your customers. Instead of waiting for the perfect product...
To calculate the phase constant of a wave, use the equation 2π/λ for wavelength "lambda" λ. The wavelength is the length of a full cycle of the wave; for example, if you place a point at the top of a "peak" on a waveform and another point at an identical spot on an adjacent...

What is the formula for degrees of freedom and when do you use this calculation in statistics? What are the degrees of freedom associated with the interaction term? Determine the correct degrees of freedom, and calculate the ratio of sum of squares to degrees of freedom....
if a is a constant that is independent of the summation index (k for example). So using these formulae, you should be able to solve your problem. edit: And keep in mind that ∑k=1n1=1+1+1+...+1=n because you go from k=1 to n while summing 1 each time (hence n t...
gaining a sound knowledge of the basics is of vital importance for students to master an academic subject."You can make comments, cite examples or use your personal experiences to develop your essay. You should write at least 15...
We use Faraday’s constant to calculate the amount ofelectric chargethat flows through a circuit per unit of time. The Faraday constant is equal to the electric charge per mole of elementary charges (like electrons). One mole is defined as the number of atoms or molecules in exactly 12 gra...
Here are some other important constants to know alongside the Boltzmann constant: Boltzmann and Planck The Boltzmann constant also occurs in the law of black body radiation of Planck and Boltzmann’s entropy formula. It’s currently one of the seven defining constants with precise definitions and ...
