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.

That depends on which angle you picked first, because that determines
which angles "the other two" are.
If you picked the right angle (90°) first, before you asked the question,
then the other two are acute angles, and they're also complementary
Hello
We know that the water's kinetic energy upon leaving will be converted into potential energy as it is projected straight up. The maximum height attained by the water is 29.6m.
We know Kinetic Energy is
1/2 * m * v^2
And Potential energy is
m*g*h
Equating,
(m*v^2)/2 = m*g*h
The mass cancels out from each side, making an object's mass irrelevant when its Kinetic and Potential energies are interchanging.
v = sprt(2gh)
v = sqrt(2*9.81*29.6)
v = 24.1 m/s

Explanation:
The region a represents the distance of the electron from the nucleus.
According to the wave mechanical model of the atom, the probability of finding an electron within a given volume element (representing the atom) is the square of the wave function psi.
Since a is the region in space where there is the greatest probability of finding the electron in the atom, it follows that distance of the electron form the atom is always a.
