Answer:
Carbon and oxygen
Explanation:
White dwarfs are the stars which have used all their hydrogen and helium fuel and now exists with only carbon and oxygen in their core. Their size reduces up to one hundredth times of the size of their sun in early stages and yet they possess the same mass.
Due to loss of fuels and impact of gravity, a young star collapses on itself leading to formation of dwarf star.
To solve this problem we will use a free body diagram that allows us to determine the Normal Force.
In general, the normal force would be equivalent to
Since the skier is standing on two skis, his weight will be divide by two
Pressure is given as the force applied in a given area, that is
Replacing F with N'
Our values are given as,
Replacing we have that
Therefore the pressure exerted by each ski on the snow is 776.01Pa
Answer:
The formula for force according to Newton's second law of motion is F=ma or force for an object to move is equal to mass times acceleration.
Acceleration or average acceleration defined as change in velocity per time.
F=ma
F=1.2x10³kg*(20m/s)(1/5s)=4.8x10³ Newtons

fthat's not the answer then i'm sorry
