Answer:
This structure can be viewed as consisting of six separate parts: (1) a nucleus, (2) a central bulge, (3) a disk (both a thin and a thick disk), (4) spiral arms, (5) a spherical component, and (6) a massive halo. Some of these components blend into each other. Three views of the Milky Way Galaxy.

Answer:
1.199km/h towards west
2.17km/h towards upstream direction
3.702km/h towards east
4.2km/h towards downstream direction
5.a.149km/h towards east
b.1043km
Explanation:
1.V p,e = Vp,w + Vw,e
= 211km/h-12km/h
=199km/h towards west
2. Vb,o=Vb,r+Vr,o
Vb,o=22-5km/h
=17km/h towards upstream direction
3.Vj,w= Vj,e + Ve,w
Vj,w = 740-38km/h
= 702km/h towards east
4.Vk,r= Vk,e+ Ve,r
Vk,r=33 - 31km/h
=2km/h towards downstream direction
5.a.Vp,e=Vp,w +Vw,e
Vp,e=216-67km/h
=149km/h towards east
b. distance =speed * time
= 149km/h * 7h
=1043km
[V p,e-velocity of plane relative to earth(ground)]
[p-plane ,w-wind ,e-earth, b-boat, r-river, o-object, j-jet, k-kayaker,]
Acceleration = change in velocity / time
change in velocity = final velocity - initial velocity
because the object is slowing down, the acceleration will be negative.
acceleration = (4-34) / 60
acceleration = -30 / 60
acceleration = -0.5 m/s^2
answer : the train is accelerating at -0.5 m/s^2
conversion factors is the answer!
