Answer:
A. 2.36
Explanation:
This is the right answer for Plato users!
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.

Answer:
The ratio of kinetic energy of accord to the truck is 1 : 3.
Explanation:
Speed, v = 30 m/s
Ratio of mass of accord to truck = 1 : 3
The kinetic energy is given by
As the speed is same so the ratio of the kinetic energies is same as the ratio of masses.
