Nebulae formed about 109 years after hydrogen and helium formed, which is the statement that most accurately sums up Kathy's mistake. The third option is the best answer.
<h3>What is the universe?</h3>
The entire cosmic system of matter and energy is the universe. The universe is made up of the Earth, the Sun, the Moon, the planets, the stars, as well as dust, gases, and rocks.
As given in the problem Kathy drew a timeline to show some of the major events that occurred during the evolution of the universe. a timeline with the smallest time labeled as big bang occurred 0s, quarks and electrons formed 10⁻¹⁰ baseline seconds, protons and neutrons formed 300 seconds, nebulae formed 3000 years and hydrogen and helium formed 300000 years
Thus, Nebulae developed about 109 years after hydrogen and helium originated, which best sums up Kathy's mistake. Therefore the correct answer is option C.

Answer:
a) t=24s
b) number of oscillations= 11
Explanation:
In case of a damped simple harmonic oscillator the equation of motion is
m(d²x/dt²)+b(dx/dt)+kx=0
Therefore on solving the above differential equation we get,
x(t)=A₀
where A(t)=A₀
A₀ is the amplitude at t=0 and
is the angular frequency of damped SHM, which is given by,
Now coming to the problem,
Given: m=1.2 kg
k=9.8 N/m
b=210 g/s= 0.21 kg/s
A₀=13 cm
a) A(t)=A₀/8
⇒A₀ =A₀/8
⇒
applying logarithm on both sides
⇒
⇒
substituting the values
b)
, where is time period of damped SHM
⇒
let be number of oscillations made
then,
⇒
