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.

Explanation:
because i don't he asking me
Answer:
a) I = 0.01029 A
, b) Q = 4074.05 J
Explanation:
a) Let's work in parts, let's start by looking for the energy consumed.
For this we use a rule of three or direct proportions if 1 kWh costs $ 0.09, how much kWh is $ 8.80
Energy = 8.80 / 0.09
Energy = 97,778 kWh
to calculate the current, we must have the energy consumed per second
Let's use a rule of three if 97,778 kWh were consumed in 24 h = 86,400 s how much was consumed in 1 s
E₀ = 97.778 1/86400
E₀ = 1.13168 Ws
the power consumed is
P = E₀ / t
P = 1.13168 / 1
P = 1.13168 W
power is
P = I V
I = P / V
I = 1.13168 / 110
I = 0.01029 A
b) the heat is given by
as the efficiency is 100%
E = P t = Q
Q = 1.131368 3600
Q = 4074.05 J
