Textbook Question
Chapter 1, Problem 49EAP

Earth Rotation Speed. Mathematical Insight 1.3 shows how to find Earth’s equatorial rotation speed. To find the rotation speed at any other latitude, you need the following fact: The radial distance from Earth’s axis at any latitude is equal to the equatorial radius times the cosine of the latitude. Use this fact to find the rotation speed at the following latitudes. (Hint: When using the cosine (cos) function, be sure your calculator is set to recognize angles in degree mode, not in radian or gradient mode.)

a. 30°N b. 60°N c. your latitude

- How far (in km) is 3.5 lightyears(ly) – the distance traveled by light in one Earth year? - How much is this same value in parsecs and (C) in astronomical units (AU)? Use 299,732 km/s for the speed of light (c) and 1 year = 365 days. Show your solution and write your answer in both regular notation and scientific notation.
Give me the right answer please and thank you, take your timeCalculate the amount of time it takes for light reflected off the surface of a distant planet to reach us.1. Sunlight takes about 8.3 minutes to travel from the Sun to Earth. What is the Sun-Earth distance in AU? (Give your answer rounded to the nearest AU).2.Light is reflected off the surface of a planet 5.2 AU away from us. How long does it take this light to reach us from the planet? Give your answer in minutes, rounded to exactly one decimal place.
Based on what you've learn on the impact of the Earth-Sun distance on the seasons, what can you say about the the cause of the seasons? (Give ALL correct answers, i.e., B, AC, BCD...)A) Earth's axis is tilted an an angle of 23.5 degrees compared to a line perpendicular (straight up and down) to its orbit, which is the main cause for the seasons.B) Earth's speed varies in its orbit around the Sun, giving us summer when Earth is moving fastest and winter when Earth is moving slowest.C) The Earth-Sun distance play a major role in creating seasons on Earth.D) The tilt of Earth's axis causes the Northern Hemisphere to be closer to the Sun than the southern hemisphere in summer, and vice versa in winter. E) The tilt of Earth's axis causes different portions of the Earth to receive more or less direct sunlight at different times of year.F) Earth's Northern Hemisphere is always tilted away from the Sun at an angle of 23.5 degrees.G) Earth's Northern Hemisphere is always tilted toward the Sun…

    For this short response assignment, your job is to demonstrate your understanding of SI units and how they can be applied on an astronomical scale. To do this, answer each of the following with a brief explanation of the mathematics used to get there.The speed of light is 3*10^8 m/s (aka 300,000,000 meters per second). What is the speed of light in centimeters per second, kilometers per second, and miles per hour? (Hint: there are roughly 1.6 km per mile and 3600 seconds per hour) Remember to show the math; If light from the closest star to our solar system takes about 4.2 years to get to us, how far away is that star in units of Gm (aka Gigameters)? Again, explain your work.
    Given the geometry shown in the picture, can you figure out where the planet is when it is moving the fastest and when it is moving the slowest?  Explain your reasoning as clearly as you can.
