For exoplanets that can be observed with both the Doppler Method and Transit Method, astronomers can determine what? :
Group of answer choices
evidence for liquid oceans
average temperature on the surface
composition of the atmosphere
average density of the planet material
Homework Answers
Answer)
An exoplanet is a kind of planet which is outside the solar system. The exoplanets revolves around the star unlike other planets which revolves around the sun. The first exoplanet was discovered in the year 1988.
For exoplanets that can be observed with both the Doppler Method and Transit Method, astronomers can determine the mass and radius of exoplanets and thus average density of exoplanets can be determined when both the method is used together. Hence, last option is correct.
Hope this helps you !!!

HD209458b was discovered in 1999, becoming the first exoplanet to be discovered using the transit method: this planet’s orbit is oriented just right, so that it regularly passes in front of its star, as seen from Earth. When this happens, it blocks out a portion of the star’s light. If astronomers notice the star’s brightness dipping for a short time over and over with a consistent period, it suggests a planet is responsible. Further observations of the star’s Doppler shift...

8. A satellite is in circular orbit about planet Rosseforp at an altitude (above the surface) h. When h = 1.75 × 104 km, the period of the orbit is T = 12 hours. If Rosseforp has a mass of 7.0 × 1024 kg, what does the satellite weigh on the surface of Rosseforp if it weighs 850 N on the surface of Earth? You are part of an expedition to planet Rosseforp (same planet as in the previous question)....

Temperatures of gases inside the combustion chamber of a four-stroke automobile engine can reach up to 1000℃. To remove this enormous amount of heat, the engine utilizes a closed liquid- cooled system which relies on conduction to transfer heat from the engine block into the liquid and then into the atmosphere by flowing coolant around the outside surface of each cylinder Assume you have a 4-cylinder engine, and each cylinder has a diameter of 8.00 cm and height of 11.9...

1. A hypothetical investigation on rider satisfaction with a particular public transit system serving commuting residents of British California (BC) and Prince Edward’s County (PEC) offers some interesting findings. The proportion of commuters from BC that indicated low satisfaction with the transit system’s service in the 2018 calendar year was 65 percent, and the proportion from PEC was 70 percent. These point estimates were based on samples of 5,380 BC commuters and 6,810 PEC commuters, whose system-using commuters number in...
