Answer:

Explanation:
Angular momentum, L = m v r
areal velocity = 
according to kepler's 2nd law

since, we know that

areal velocity= 
now substituting value of v in areal velocity we get

hence from above equation of rate of change of area swept i.e. areal velocity is proportional to 
Chesapeake Bay is located east of D.C.
