However, the characteristics of the world span an enormous range of numbers. The mass of an electron is 0.000000000000000000000000000000911 kg (incredibly tiny!). The mass of the Sun is 1,989,000,000,000,000,000,000,000,000,000 kg (incredibly massive!). If you had to write, interpret, or use these numbers as written, you could very easily end up making a minor math error. Scientific notation was invented to easily express numbers that are too large or too small to be conveniently written in decimal form. The advantages of scientific notation are it 1) is compact, 2) helps articulate significant figures, and 3) works with numbers of any size. The traditional format for numbers written in scientific notation is m × 10 n is where m is a number between 1 and 10 and n is an integer (either positive or negative). For the examples above, the mass of an…arrow_forward
- Which of the following is least reasonable regarding the "water hole"? Group of answer choices It consists of frequencies which are greater than the frequencies of atmospheric emissions. It relates to the natural frequencies of vibration of hydroxyl (OH) and hydrogen (H), respectively. It occurs in that part of the electromagnetic spectrum where the galactic "noise" from stars and interstellar clouds is minimized. It is considered the "electromagnetic oasis" for interstellar communication. It corresponds to wavelengths in the 18-21 cm range.arrow_forwardHow do we know? How does the scientific method give scientists a way to know about nature?arrow_forwardYou record the spectrum of a distant star using a telescope on the ground on Earth. Upon analysing the spectrum, you discover absorption lines spaced at intervals typical of oxygen atoms. Which of the following are possible interpretations of this evidence? Select all that apply. The width of the spectral lines gives the diameter of the star The star is likely orbited by habitable planets with breathable atmospheres. The height of the spectral lines above the star's general blackbody spectral curve tells us how much oxygen is in the star The atmosphere of Earth contains oxygen The red or blueshift of the set of lines can tell us the speed of the star's motion toward or away from usarrow_forward
- Think of our Milky Way Galaxy as a flat circular disk of diameter 100,000 light-years. Suppose we are one of 1000 civilizations, randomly distributed through the disk, interested in communicating via radio waves. How far away in light years would the nearest such civilization be from us on average? Show your working. (Hint: Begin by calculating the area of the disk. Find the area of one of a 1,000 squares. Consider the separation of the centres of two adjacent squares.)arrow_forwardThere is only one part to this question and I need to know the particles per second.
