Some types of variable star vary very regularly, and their time of maximum and minimum can be found from data. Others are irregular and the only way to find the maximum and minimum is to keep observing them and measuring the brightness.
No, it is a continuous process but not a continuous variable. The magnitude of star-shine, across all stars is a continuous variable. The magnitude of a star's shine over time is a continuous variable.
If I am not mistaken, the question should be "What is an independent variable?" The answer is this: An independent variable is a variable whose results are independent of all the other variables measured in the data sets/experiment. For an exaggerated example, if one were to perform Van de Graff Machine experiment where the values measured are Static Energy, Time, and The Number of Stars Present in the Sky, one would be likely to find the Statics Energy and Time would have a direct relationship whereas The Number of Stars Present in the Sky would have no relationship to Static Energy or Time.
Variable stars and main sequence stars can have similar brightness. Variable stars, like Cepheid variables, can fluctuate in brightness over time, while main sequence stars maintain a relatively stable brightness due to their fusion processes.
Stars that brighten and then fade are known as variable stars. Their brightness changes over time due to various factors, such as pulsations, eclipses in binary systems, or eruptive events. Studying variable stars can provide valuable information about the stellar properties and their evolution.
When graphing in science, the independent variable is the variable graphed on the x-axis; the dependent variable is the variable graphed on the y-axis. To determine the name of the variable, one only needs to find the variable changed by the other variable and the variable remaining unaffected by the other variable. For example, someone wanted to find the the increased temperature of water over a stove during a period of time. Since increasing water temperature cannot affect time and increasing time can affect the water becomes the dependent variable and time becomes the independent variable.
there are three variable are to find but in newton only one variable is taken at a time of a single iteration
To find the minimum deceleration, you would need to calculate the change in velocity and time over which the deceleration occurs. Then, you can use the formula a = Δv / t, where a is the acceleration, Δv is the change in velocity, and t is the time. The minimum deceleration would be the smallest value calculated using this formula.
who to control one variable at time
Get in your car.Drive to the main office.That will give you a minimum time.How long it actually takes is highly variable and it's not really possible to give you an answer.
The manipulated variable is what you change (the shape of the container) The responding variable is the result (the temperature at which the water in the container freezes). (Don't forget the time factor!)
In a position versus time graph, time is typically considered the independent variable because it is controlled by the experimenter and is used to measure the dependent variable, which is position. The position of an object (dependent variable) changes over time (independent variable), and thus position is plotted against time to show how it varies based on the passage of time.
Nothing, but you can speak about the lifetime of a variable: the time-interval in which the variable exists.
