What are the strengths and limitations of the Doppler and transit methods? What kinds of planets are easiest to detect with each
mojhsa [17]

Answer:

Yes, there are certain planet that are not detected even if they are large.

Explanation:

  • The Doppler method is the radial-velocity method, and also an indirect method finding the extra solar planets and the brown dwarfs. While the transit method is a phenomenon only the celestial bodies are directly between a large body and an observer body.
  • However, the transit method of the transiting planet is low as it depends on the alignment of the three objects that are in a near perfect straight line patterns. And that of the Doppler method that it can only measure movements along that line of sight, and this depends on the estimates of inclination of the planet's orbit to determine its mass.  
  • <u>Thus of a planet is found by both these methods we can find its density, and an indication of its composition.</u>

Using complete sentences, identify the three major mountain ranges in the United States, and describe the relative location of e
Tpy6a [65]

The 3 major mountain ranges in the United States are the Pacific ranges and Rocky Mountains in the west and the Appalachian mountains in the east. The Pacific ranges are on the northwestern coast of the United States. The Rocky Mountains are in the western United States but east of the Pacific ranges. They extend all the way from Canada into Mexico and cover 8 states. The Appalachian Mountains are near the East Coast of the United States. They extend from Canada to Alabama. The main difference between the eastern mountain ranges and the western mountain ranges is their ages and heights. The Appalachian Mountain range is the oldest range in the United States. Because of this, the range has faced weathering and erosion, which has worn the mountains down. The highest peaks in the Appalachians are only 6,000 feet. The ranges in the west are much younger and in some cases still growing. The mountains in the west are much higher than those in the east, with peaks over 14,000 ft.
