Why did Aristarchus make his measurements of the Sun's distance at the time of quarter moon?
Because when the Moon is at a "Quarter Phase", exactly half of the Moon's face is lit by the Sun. That means the Sun-Moon-Earth angle is 90 degrees. He could use that fact to estimate the Moon's distance by geometry.
How many light years is the heliopause to the sun?
Voyager 1 was able to perform measurements and establish the distance as 121 AU (18 billion km). This would make the distance about 0.0019 light years.
The force between a planet and a spacecraft is 1 million newtons.What will the force be if the spacecraft moves to half its original distance from the planet?
The force is inversely proportional to the square of the distance. So, half the distance means four times the force. So, the answer is: 4 million newtons. additional note: This is true only if the distance referred to is the distance to the center of the planet or if the distance to the planet is great enough to make the radius of the planet insignificant.
What are the uses of michelson's interferometer?
Michelson's interferometer is used in interferometry to make precise measurements of distance, wavelength, and index of refraction. It is also used in the field of spectroscopy to analyze the interference patterns of light to determine the properties of materials. Additionally, it is used in the detection of gravitational waves.
How do you properly make the word half-moon plural and possessive?
The plural form of the compound noun half-moon is half-moons.The plural possessive form is half-moons'.Example: The necklace was made up of silver half-moons. The half-moons' shimmer lit up her face.

Who measured the distance around the earth?
Aristarchus, a Greek ScientistWait till the moon is EXACTLY half full. Then the Earth, the Moon, and the Sun form a right triangle with the right angle at the moon. Measure the angle between the Moon and the Sun, and with the Moon's distance (previously found by triangulation), derive the Sun's distance as Moon's distance divided by the cosine of the angle. The uncertainties in that "exactly' make this a shaky method. Aristarchus himself got the Sun 30 times as far away as the Moon, when the correct value is nearly 400 times.
What measurements are necessary to make in order to compute the average speed of an object?
1) The total distance travelled.2) The total time taken.Speed = Distance/Time
How many measurements make an inch?
No measurements necessarily make an inch.
How many light years is the heliopause to the sun?
Voyager 1 was able to perform measurements and establish the distance as 121 AU (18 billion km). This would make the distance about 0.0019 light years.
What does a ruler measure?
A ruler is used to make linear measurements like length, width and height.
What is to make smaller measurements that are in proportion to the measurements of the large object?
Scaling.
What equipment can be used to make accurate measurements of distance traveled during an attempt on land speed record?
To make accurate measurements of distance traveled during an attempt on a land speed record, equipment such as GPS devices, accelerometers, and wheel encoders can be used. These tools can provide precise data on speed, distance, and acceleration throughout the record attempt. Additionally, utilizing high-quality cameras or laser-based systems can help validate and cross-reference the measurement data for improved accuracy.
Distance from Pittsburgh to mcallen tx?
The distance is about 1705 miles. It should take 27 and a half hours to travel it. The time is going to vary depending on traffic and how many stops you make.
What equipment is used to make accurate measurements of these two quantities during an attempt on the LSR?
the equipment used to make accurate measurements of is a watch
Why are do scientist use different distance measurements?
For most purposes, scientists will use SI units.Astronomers sometimes use astronomical units, light-years, or parsecs to express distance. The reason is that they make the distances easier to grasp. In particle physics, a different system of units called "natural units" is often used. The reason is that it makes certain formulae simpler. For instance, the speed of light is defined to be 1 - so if an object has a speed of 0.5, it means that it is moving at half the speed of light.
Is meter in both the US and metric system?
The meter is not part of the U.S. system of measurements. The unit of length in the U.S. system is the foot (or inch or or yard or mile, depending on what one considers the "foundational" measure of distance). However, many Americans are quite able to make measurements in meters and kilometers.
