Answer:
Astronomers use radar measurements, telemetry and exploration of solar system to get precise measurement of astronomical units.
Astronomers use parallax techniques. They measure the distance between the Earth and solar planets. Astronomers use parallax techniques to conduct parallax measurements which gave them accurate and precise values of the length of astronomical units
Explanation:
Astronomical unit is a unit length which is the average distance between the Earth and the sun which is about 150 millions kilometers.

Answer: Chlorine gas is produced when sulfuric acid is mixed with chlorine bleach.
Explanation: This reaction is a function of the change in pH of the solution from alkaline to acidic combined with the strong oxidant properties of hypochlorous acid.

Answer:
Explanation:
Search for "Rosalind Franklin: DNA's unsung hero - Cláudio L. Guerra" which basically summarizes what Rosalind did and how we was snubbed from receiving the noble prize even though she had vast and critical evidence to highlight the structure of DNA. You can look for more sources but I can tell you a quick recap:
Rosalind Franklin was born in an era where women scientists or workers were very uncommon and they were even discriminated and looked down upon. After her phD., she was working to find the structure of DNA and soon she was able to form an x-ray image of it. However, her lab colleague took the picture and showed it to other scientists (Watson and Crick) without the knowledge or permission of Rosalind. Here Rosalind was working on analyzing her data and on other part of world Watson and Crick were doing the same. Based on Watson and Crick's analysis, they came up with the correct structure of DNA and soon Rosalind got done as well. Both submitted their paper to journal, however, the journal placed Watson and Crick paper before Rosalind (making it look like Rosalind just confirmed what Watson and Crick proposed). This made it look like Watson and Crick were geniuses behind DNA structure whereas, in reality, it was Rosalind. She would have received Nobel Prize but she died of Cancer and Nobel prizes are not awarded to dead people.
Answer:
False, the object is stationary therefore the object is balanced.
