Home astronomy homework solutions

Remember that multiplications and divisions are done before additions and subtractions. The time is takes an object to fall from a height h is:

Some of these questions may also appear on the exams. B The star will set at the same position, but will be *astronomy homework solutions* hours past setting at 10 p.

A Stars rise, transit and set 4 minutes earlier per day or 1 hour earlier every 15 days. B b where will that star set?

Therefore, the farther an object is away from us, the farther back in time we are looking to see it.

The meridian altitude of the celestial equator is equal to the observer's co-latitude 90o - latitude.

Therefore in astrknomy hours, Betelgeuse will be **astronomy homework solutions** west of the celestial meridian. The rocket equation can be rewritten to find how much payload we can lift if we are given a value for Part II - Staying in Space.

Therefore, the farther an object is away from us, the farther back in time we are looking to *astronomy homework solutions* it. CourseMerit is not sponsored or endorsed by any college or university.

The earth's revolution around the sun at **astronomy homework solutions** rate of about 1o per day accounts for the 1o shift in the stars location relative to the horizon. If you lived at a latitude of 25o North

For full credit, always show your work and explain how you got your answer. Therefore what would be the meridian altitude of the celestial equator?

*Astronomy homework solutions* Angle a How long until the next transit if a star has an hour angle of -5h b How long until the next transit if a star has an hour angle of 3h?

What are the pros and cons of the Celestial Coordinate System R. At the equator, the celestial equator runs from cardinal point east to the zenith to cardinal point west.

B b where will that star set? In one month, the star will set two hours earlier - 8 p. B The star will set at the same position, but will be two hours past setting at 10 p. Set up another ratio: Staying in space is hard. This is the nearest large galaxy. Show all work, including units. Use a calculator whenever necessary. A Since the celestial equator is the projection of earth's equator perpendicular to its surface, it projects from your feet to your head to the zenith if you were standing at the equator.

If you can throw an object horizontally, fast enough, so that is goes 3, meters before it falls 1 meter, that object will never hit the surface of the Earth. Set up a ratio: Numbers such as , are written as 2. A The diurnal rate of the stars is 15o per hour to the west with respect to the horizon. Attachment Astronomy Homework 1 Solution. Be careful about units! Please be as neat as you can. You need, and therefore must measure, Vega's declination Therefore, the star will be rising in 6 months at 10 p.

Hour Angle a How long until the next transit if a star has an hour angle of -5h b How long until the next transit if a star has an hour angle of 3h? NO stars are circumpolar at the equator. What are the pros and cons of the Celestial Coordinate System R. The time is takes an object to fall from a height h is: The meridian altitude of the NCP is simply equal to the observer's latitude.

If you lived at a latitude of 25o North For the star in question, it will be above the horizon for exactly 12 hours. For full credit, always show your work and explain how you got your answer. The Earth is really big so the curve is very slight.

In order to throw and object, straight up, to a height h, you have to throw it with a velocity v:
