The beginning of the universe is from the big bang which is a massive explosion.
The Big Bang is the moment when the universe began 13.8 billion years ago with the explosion of a small, dense fireball. However, what caused the explosion in the first place remains a mystery.
A Big Bang event is a physical theory that explains how the universe expands from a dense and hot initial state. Various cosmological models of the Big Bang explain the evolution of the observable universe from the earliest known epochs to later large-scale forms.
In 1929, Edwin Hubble provided the first observational evidence that the age of the universe is finite. Using the largest telescope of its time, he discovered that the farther away a galaxy is from us, the more it appears that the space is expanding from us in all directions.

Answer:
C. It is converted into another form, mainly kinetic energy
Explanation:
Potential energy is energy available to be used in an object that isn't currently moving. When an object begins moving, potential energy becomes kinetic energy.
Answer:
When the electrons jump to a higher energy state, they release energy as electromagnetic radiation, light.
Explanation:
When the solar wind gets past the magnetic field and travels towards the Earth, it runs into the atmosphere. As the protons and electrons from the solar wind hit the particles in the Earth's atmosphere, they release energy – and this is what causes the northern lights.
We have:
s=3,7km (3700m)
u=0
v=26m/s
a=
t=
We look up for a formula to solve for a:
v²=u²+2as u²=0 so
v²=2as
(26m/s)²=2a3700m
676/7400=a
a=0,09m/s²
