The gas shell of a planetary nebula is expanding (away from the central star) at 20 km/s. The nebula currently has a diameter of 1 light year. What is the age of the planetary nebula(time since the gas was ejected)?© BrainMass Inc. brainmass.com October 24, 2018, 6:02 pm ad1c9bdddf
This problem uses the basic formula relating velocity, distance and time
v = d / t or, for this problem, t = d / v.
What is moving in this problem is the outer layers of the ...
This solution computes the age of the nebula.
Compare and contrast relative age dating with radiometric age dating. Discuss the limitation of each?View Full Posting Details
