What are three physical factors that determine a star's brightness?
Three physical factors that determine a star's brightness are its temperature (hotter stars are brighter), size (larger stars are generally brighter), and distance from Earth (the closer a star is, the brighter it appears).
How do you use a scale bar?
A scale bar on a map or diagram provides a visual representation of the ratio between a unit of length on the map and the corresponding distance on the ground. To use a scale bar, simply measure the distance on the scale bar that represents the desired distance on the map, and then apply the scale ratio to determine the actual ground distance.
The distance from one crest to another crest is call?
In a wave train, the distance between successive wave crests is called the "wavelength".
What is another word for blue planet?
Earth. It looks blue from a distance
Why one star may appear brighter than other star?
One star may appear brighter than another star due to several factors, including its size, temperature, distance from Earth, and luminosity. A larger, hotter, closer, or more luminous star will typically appear brighter in the night sky compared to a smaller, cooler, more distant, or less luminous star.

How can you determine if an object has moved?
Judge by the distance it has moved in relation to another object.
What are two factors that determine gravitational force on another object?
Mass and Distance
What feature on a map helps determine distance from one place to another?
Scale
What are two factor the determine an object gravitatoinal potencial energy?
Mass and distance to another object with mass.
How is the calibration thermometer used?
A calibration thermometer is used to check the accuracy of another thermometer. By comparing the readings of the two thermometers at various temperature points, you can determine if the thermometer being tested is displaying correct temperature measurements. This is important for ensuring the reliability of temperature readings in various applications, such as scientific experiments or food preparation.
How can you determine the relative motion of another object?
You can determine the relative motion of another object by observing its motion in relation to a fixed reference point or another object. This can involve comparing the speed, direction, and distance of the object relative to yourself or another point of reference. Calculating the velocity or acceleration of both objects can also help determine their relative motion.
Why you calculate enthapy?
Generally enthalpy is analgous to the energy of a material at a particular temperature and pressure. It is calculated to determine the energy a material holds, or more often, enthalpy differences are calculated to determine how much energy is required to bring a material from one temperature and pressure to another temperature and pressure.
What is an instoment used to measure the stars?
An instrument used to measure stars is called a spectrometer. It analyzes the light emitted or absorbed by stars, allowing astronomers to determine their composition, temperature, distance, and velocity. Another important tool is the telescope, which magnifies distant celestial objects, enabling precise observations and measurements of stars’ positions and brightness. Together, these instruments enhance our understanding of the universe.
What methods can be used to determine a kitten's gender ID?
To determine a kitten's gender, you can look at their genitalia. Male kittens have a small distance between the anus and genital opening, while female kittens have a larger distance. Another method is to consult a veterinarian for a professional opinion.
When it is hotter is it closer?
Not necessarily. The temperature of a planet or star is not directly related to its distance from another object. Multiple factors, such as the object's composition, atmosphere, and proximity to a heat source, can influence its temperature.
How are scientist able to determine the distance between genes?
Scientists can determine the distance between genes on a chromosome using techniques like genetic mapping. By analyzing the frequency of genetic recombination events between genes, they can estimate the distance between them. Another method is to sequence the DNA and use physical mapping to measure the actual physical distance between genes on the chromosome.
