The total amount of calories that you take in, and how much you exercise during the day, are what affect your weight. However, many people do tend to overeat and choose high-calorie foods as snacks at night, both of which will cause weight gain.
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
Note about the question:
I failed to find the complete question, but I am going to give two possible options about the Punnett square that might be useful. In any of the cases, the answer is the same.

Explanation:
Due to technical problems, you will find the complete explanation in the attached files.
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
