Match the items below with the correct type of supernova.

MSS:

WD:

Can only occur in a galaxy with ongoing star formation.

Can only occur in a binary system.

Star explodes completely, leaving no compact object behind.

Black hole or neutron star left behind.

Spectra always lack strong hydrogen lines.

Has a brighter peak luminosity.

Can occur in a very old star cluster.

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
