Each supernova type is distinct in initial components, process, and observational properties. sort the following characteristics as to whether they describe a type i or type ii supernova.

a. low-mass star
b. high-mass star
c. carbon-detonation supernova
d. hydrogen-poor
e. hydrogen-rich
f. core-collapse supernova
g. graph with green line (initial increase followed by steady decrease)
h. graph with red line (higher initial luminosity but luminosity constant from 25 to 100 days before decrease)

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

Astate of matter all that has define volume and can flow is a(n)
