Ymorist [56]
First is the Nebula, a cloud of gas and dust in space where stars are born.
Second is a Star, Luminous globe of gas producing its own heat and light through nuclear reactions.
Third is Red Giant, a large bright star with cool surface, it is formed during the later stage of evolution of a star like our sun.
Fourth is the Red Dwarf, which is very cool, faint and small star.
Fifth is White Dwarf, this is a very small and the last stage in the life cycle of a star.
Sixth is the Supernova, the explosive death of a star
Lastly is the Blackhole, where it is believe to form from a massive stars at the end of their times

HELP PLEASE IM STUCK ON THESE QUESTIONS
Diano4ka-milaya [45]

Answer:

a = 10 m/s²

F = 2000 N

m = 8.57 Kg

Explanation:

1) What is the acceleration of a 40 kg object pushed with a force of 400 N?

Acceleration of object = ?

Mass of object = 40 Kg

Force on object = 400 N

Solution:

Formula:

F = ma

by putting values,

400 N = 40 Kg × a

a = 400 N/ 40 Kg   ( N = Kg.m /s²)

a = 10 m/s²

2) What is the force on an 800 kg rock being thrown at 2.5 m/s2?

Acceleration of object = 2.5 m/s²

Mass of object = 800 Kg

Force on object = ?

Solution:

Formula:

F = ma

by putting values,

F = 800 Kg × 2.5 m/s²

F = 2000 Kg. m/s²  ( N = Kg.m /s²)

F = 2000 N

3) What is the mass of a ball being rolled at 3.5 m/s2 from a 30 N force?

Acceleration of object = 3.5 m/s²

Mass of object = ?

Force on object = 30 N

Solution:

Formula:

F = ma

by putting values,

30 N = m ×  3.5 m/s²

m = 30 N / 3.5 m/s²   ( N = Kg.m /s²)

m = 8.57 Kg
