Force is equal to mass multiplied by acceleration. Hope this helps!
Answer:
Decreasing in altitude and increasing in velocity
Explanation:
The formula for potential energy is:

where m is mass, g is constant gravitational energy and h is the potential altitude.
The formula for kinetic energy is:

where v is the velocity
Since m,g are constant, to convert from potential energy to kinetic energy, h must decreases while v increases. For example dropping an object from a height.
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.
The "newton-meter" that is a unit of work or energy
is identical to the Joule.
