Will give brainlest if correct

1  is black hole and description is atract all matter and energy

2 is nebula  a low mass star that has shed its outer layer

3 is white dwarf shells that are cast awat from a low mass star

4 is red super giant a heavy star that expands and gives off large amounts of light

1- black hole (attracts all matter and energy that come near by)

2- Planetary Nebula ( shells that are cast away from a low-mass star)

3- Red Supergiant ( a heavy star that expands and gives off large amounts of light)

4- white dwarf ( a low mass star that has shed its outer layers)

Step-by-step explanation:

white dwarf is the core of planetary nebula ,planetary nebula are the shells that have been " removed "

black hole basically just takes in everything in that comes near it and a red supergiant is a large star

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
