How do you know when a particle is a beta emitter?
In the physics laboratory, an investigator might use a proportional detector or a scintillation counter to determine when a source is beta emitter. The problem is that a lot of "generalized" detectors (like a Geiger counter) are not specifically set up to detect only beta radiation, and that makes them unsuitable to the task of looking at just that one type of particulate emission. Let's look a bit further.Beta radiation, which is emitted from a radioactive source that decays by beta emission, is either a positron or an electron. Either one is emitted in beta decay (but not both), and different isotopes decay by one type of beta decay or the other. Further, the beta particle emerges from the beta decay event with considerable kinetic energy. But beta radiation can be stopped by a sheet of paper, so the counter must be set up with a thin window that will allow beta radiation to penetrate it. By choosing an appropriate thickness of material, any alpha radiation will be stopped by the window, and beta radiation will penetrate it. Gamma rays will easily penetrate a window, but the design and construction (as well as the settings) of the detector will minimize any response to gamma radiation.It might be possible to test the source material to determine what element it is. By knowing the element and its "history" as such, the particular isotope of that element might be determined. The isotopes of the elements have been researched, and a good table of nuclides will allow an investigator to determine whether the isotope being investigated is one that undergoes beta decay.
How many protons will uranium have after releasing a beta particle?
It depends on whether the beta decay sequence is beta- or beta+. In beta-, the atom will gain a proton, changing into neptunium. In beta+, the atom will lose a proton, changing into protactinium.
How can you determine whether a measured value of a substance represents an extensive property?
Its value will be reduced as the numbers of moles of the materials is reduced
How can you determine the number of protons in an atom changes?
For the alpha decay the number of protons decrease with 4; for the beta minus decay the number of protons ih higher with 1.
What is beta perticle?
The beta particle is an electron.
How do you determine a portfolio's beta value?
The beta of a portfolio is the weighted average of individual betas of assets in that portfolio. There is an example of portfolio beta calculation here: http://www.riskyreturn.com/portfolio_beta.html
Importance of beta value in investment decision?
In investment decision, beta is associated with
What is McDonald's beta coefficient?
Standard & Poor's gives McDonald's beta as 1.32. Value Line says 0.75.
Why is beta the correct measure of a stock riskiness?
Beta measures a stock's volatility (the swings up and down in price). The market as a whole has a beta of 1.0, but each stock is determined a beta value from a history of it's stock movements. Riskiness equates to the stock losing value and high beta stocks are more prone to falling faster.
Rf value of beta-carotene?

What are the common application of kirchhoff's laws?
-determine the direction and value of current -determine the potential difference -determine the value of resistance
Can beta particles pass through aluminum?
Yes, beta particles can pass through aluminum. However, the thickness of the aluminum and the energy of the beta particles will determine how many particles can pass through. Thicker aluminum will block more beta particles compared to thinner aluminum.
There are 20 stocks in portfolio with a total beta of 1.65 you sell 5 stocks from portfolio with a total beta of 2.0 each stock weighs 5 after selling the 5 stocks what is the beta?
Say, you hold 1,000 shares of Bharti Airtel, 300 shares of Infosys, 500 shares of Reliance Industries and 700 shares of Hindustan Unilever. In order to completely hedge the portfolio, you need to arrive at the total beta value of your holdings. To begin with, get the beta of individual stocks against the index (available in NSE monthly newsletters). Now, multiply individual beta value of stocks to the current value of investment in that stock. Then, divide the sum of all these numbers with the total value of your investment (current) to arrive at the overall beta of your portfolio.
How is beta detected?
Beta particles can be detected using instruments such as Geiger-Muller counters or scintillation detectors. These instruments can measure the ionizing radiation produced by beta particles as they interact with matter. The detection process involves counting the number of interactions to determine the presence and intensity of beta radiation.
If the terminal side of an angle beta is in quadrant III what is the sign of each of the trigonometric function value of beta?
Tangent and cotangent positive; other 4 negative.
How does an insurance company determine the value of a stolen motorcycle?
A.C.V. (Actual Cash Value)and or (loan to value) blue books. Your purchase receipt will help determine the real value.
What is Hypothesis Testing of Beta Value?
Probability of failing to reject a false null hypothesis.
