Answer:
A.
Explanation:
If its at a height the Gratitude of it falling down with only Gravity if Any other Forces are acting on it so as Friction But Sideways.
Answer:

Explanation:
ΣF=ma
The two forces at play are the force applied and the force due to friction. As they are opposing forces set the direction being pushed as the positive in the x direction. the equation you come out with is 60 - 15=(15)A (we know mass to be 15kg). Solve for 3 m/s^2.

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.
