There are 3 states of matter. Solid, Liquid, Gas. An example of each would be ice, water, steam,
F = ma
Rearrange this so acceleration is the subject:
A = f/m
Now input your values into this equation for the first question :
A = f/m
A = 15/45
A = 0.33333333 m/s
Then using this same equation change the force of 15 to 25 :
A = f/m
A = 25/45
A = 0.55555556 m/s
For the last question keep the force of 15N but change the mass to 70kg into the same equation :
A = f/m
A = 15/70
A = 0.21 m/s (rounded)
In a high-mass, main-sequence star energy produces at a faster rate by using carbon in a process that fuses hydrogen to helium.
A high mass star produces energy by the fusion of hydrogen to helium.
But in this process, oxygen, carbon and nitrogen act as catalyst to accelerate the energy generation process.
Energy burn very quickly and at a faster rate in a giant and high mass star than in a low mass star.
A star 10 x the mass of siun can live upto 20 million years whereas low mass start has greater lifespan than the present age of the universe.
