The shock wave produced by the supernova expended from the center and is currently at the edge of the observed Cas A remnant. Using the information in the previous problem, compute the average speed of the shock wave in units of km/s.
Transcribed Image Text:Consider the image above of the
Cassiopeia A (Cas A) supernova
remnant. The supernova explosion that
caused this remnant was observed on
earth about 300 years ago. It is about
3000 pc away. Since that time, the
shockwave from the supernova has
expanded to form the roughly spherical
cloud pictured above. From the center
point to the edge of the cloud is about
3 pc. Compute the angular diameter of
the Cas A supernova remnant as viewed
from Earth. Express your answer in
arcminutes.

Expert Answer
Step1
a)
The distance from the eanth of supernova Cas A is d= 3000pe
The radius ef the spherical clovd P= 3 pc
Step2
b)
supornere
The angulan diarmeter d = 20
From the geometry
tan@ =
> 9 = ten 3
3000
» e = 0.0573°
* 0 = 0-057 X 60 ancmin
Then engulan dimeter
d = 20 = 6. g8 arcmin
