ok i have finals this week and i have a study guide for astronomy that ive been working on for the last 2 days. ive gotten most of the questions done but there are still soe i cant seem to find te answers so if u could help me that would be cool. ive gotten most of them but still i need help on some of them.
1.waht is the range of values for right ascension?
2.scientists do not accept the petolimiac model because? now i think the answer to this one is because it stated that athe earth was the center of the universe and didnt name all of the planets)
3. how did kepler describe the orbits?
4.what was brahes contribution to astronomy?
5.who developed the law of universal gravitation?
6.how does the force of gravity change with mass and distance?
7.how is wave velocity calculated?
8. what is wave amplitude?
9.waht is true about sound wave and emr?
10. what is constant for all types of emr in a vacuum?
11.what is the relationship between the waves in electric and magnetic fields?
12. whicch type of emr has the lwesst frequency
which types can penatrate the atmospere?
why are x-ray telsecopes in orbit?
emr with a wavelength of 700 nm is?
why are there no radio telescopes in space?
what emr are our eyes most sensitive to?
who developed the3 laws dealing with spectral lines?
what can emmision spectra identify?
what are fraunhaufer lines?
what information about an astronomical object can be determined by observong its spectrum?
wat is the pimary purpose of an astronomical telescope?
thats all for now.
