How do scientists know what the sun is made of?
Scientists know what the sun is made of by studying its spectrum. By analyzing the light emitted by the sun, they can identify the different elements present in its atmosphere based on the unique patterns of absorption and emission lines. This approach allows scientists to determine that the sun is mainly composed of hydrogen and helium, with trace amounts of other elements.
Describe Two ways scientists calculate the age of the universe?
By measuring the rate of expansion of the universe using the Hubble constant and then calculating backwards to determine when the universe started expanding, scientists can estimate the age of the universe. By studying the cosmic microwave background radiation left over from the Big Bang, scientists can infer the age of the universe by measuring the temperature fluctuations and using them to determine the time since the universe began.
What is the difference between Aston's mass spectrograph and Dempster's mass spectrometer?
Aston's mass spectrograph is a magnetic sector mass spectrometer that separates ions based on their mass-to-charge ratio using magnetic and electric fields. Dempster's mass spectrometer is an early design of a mass spectrometer that used electric and magnetic fields to separate ions based on their mass-to-charge ratio. Aston's design was an improvement over Dempster's, offering higher resolution and precision in analyzing isotopic composition.
How can scientists keep track of tornadoes?
Scientists track tornadoes using Doppler radar and reports from eyewitnesses.
What sentence can you make using the word Big bang theory?
The Big Bang Theory is widely considered by scientists and theologians as the way in which the universe started. Even the Pope accepts it.
What is a calutron?
An electromagnetic apparatus for separating isotopes of uranium and other elements according to their masses, using the principle of the mass spectrograph. It lost me at 'mass spectrograph'.
What are the evidences for Helium and Hydrogen in sun?
Scientists can determine the contents of stars using spectrometer (spectrograph or spectroscope.) Basically different compounds give off different wavelengths of of light. By measuring the light you can identify the compound.
How have scientists determined the age of earth?
Scientists have determined the age of the Earth using various methods, most notably radiometric dating of rocks and minerals. By measuring the decay of certain radioactive isotopes within these materials, scientists are able to calculate the age of Earth to be approximately 4.54 billion years old.

What is the roundest object in the universe and how is its shape determined?
The roundest object in the universe is a silicon sphere created by scientists. Its shape is determined by using advanced technology to measure its roundness at the atomic level, ensuring it is as close to a perfect sphere as possible.
What instrument photographs light wavelengths to find movements of space objects?
Spectrograph for anyone using the Basic Skills/ Earth and Space Science workbooks!
What scientists have made discoveries about planet uranus?
It was William Herschel he discovered it in 1781 when he was using a telescope he built himself when he spotted a dim object he watched it for years and determined it was a planet.
How did scientists determine the location and size of the underwater mountain chain?
Scientists determined the location and size of the underwater mountain chain through methods such as bathymetric mapping using sonar, satellite data, and submersible vehicles. By studying these tools and data, scientists were able to create detailed maps of the seafloor, revealing the location and size of underwater mountain chains.
A sentence using the word determined?
I am determined not to answer your question.

Why solar eclipses can be determined in advance?
Because the sun and moon's paths are regular (i.e they follow an orbit that is well-known to scientists), the time that they align themselves with the Earth can be calculated by using their velocity on their paths using relatively basic maths
What is a carbon arc emission spectrograph?
A carbon arc emission spectrograph is a piece of scientific equipment. Emission spectography is used to measure radiation intensity, and provides information about atoms and molecules as well as chemical composition of objects.
