If the radius of Betelgeuse varies by 60% within three years, its luminosity will also change proportionally. Since absolute magnitude is related to luminosity, the ratio of the two absolute magnitudes will be the square root of the ratio of the luminosities. So, the ratio of the two absolute magnitudes will be approximately 1.22.

What is the relative humidity when the dry-bulb temperature is C and the wet bulb temperature is C?
50 percent
When the relative humidity is 100 percent the air temperature is equal to the dew point temperature?
Yes, when the relative humidity is 100 percent, it means the air is holding the maximum amount of moisture it can at that temperature. At this point, the air temperature is equal to the dew point temperature, causing condensation to form as the air becomes saturated with moisture.
IF The weight of a rock is measured at 2.5 pounds what is the percent error in this measurement?
The percent error is calculated by taking the absolute difference between the measured value and actual value, dividing it by the actual value, and then multiplying by 100. If the actual weight is not provided, the percent error cannot be calculated.
The smallest intensity of a stimulus that you can detect 50 percent of the time is?
The smallest intensity of a stimulus that you can detect 50 percent of the time is called the absolute threshold. This threshold varies depending on the sensory system and the specific stimulus being measured.
Why does the percent error calculation have to be performed in celsius rather than kelvin?
That is just utter nonsense. Kelvin is the absolute scale so percentages should be calculated in Kelvin and not Celsius.
What temperature would the cold reservoir need to be for a Carnot engine to achieve 100 percent efficiency?
For a Carnot engine to achieve 100 percent efficiency, the temperature of the cold reservoir would need to be absolute zero (0 Kelvin). This is because the efficiency of a Carnot engine is given by 1 - (Tc/Th), where Tc is the temperature of the cold reservoir and Th is the temperature of the hot reservoir, and efficiency is maximized as Tc approaches absolute zero.
The absolute value of 8 percent?
0.08
What temperature is required to transfer waste heat to the environment for a heat engine to be a 100 percent efficient?
In order for a heat engine to be 100 percent efficient, the temperature of the cold reservoir where waste heat is transferred should be absolute zero (0 Kelvin). This is not achievable in practice, as it violates the second law of thermodynamics.
What covers 40 percent of Idaho?
absolute nothingness
What is the absolute value of 25 percent?
The absolute value of a positive number is the same as the number. So, the answer is 25%.
What percent live in absolute poverty?
13% to 17% of all Americans live in absolute poverty in the U.S.
What is a high percent error mean?
high percent error is the absolute value of something that is multiplied
Absolute percent error?
Absolute percent error is the Percent Difference between two values.Applying the equation for Absolute error.For example: 21.571 is the True value 20.000 is the Recorded Value.Thus: (Recorded Value) - (True value) = Absolute error (21.571) - (20.000) = 1.571We modify this to match the following:(Recorded Value ) - (True value) / True value * 100This will give us a percent error of:(20.000 - 21.571) / 21.571 *100 = -7.28%
Is 0.08 percent less than 1.0?
Yes, in absolute terms. But 0.08 percent of 1,000,000 is bigger.
What is the volume percent of Toluene in room temperature?
percent volume of toluene at room temperature is 31.84%.
What is 35 percent in Fahrenheit?
Percent is not a unit of temperature.
What is mean absolute percentage error?
The mean absolute percent prediction error (MAPE), .The summation ignores observations where yt = 0.
