There are 3 main pieces of evidence that support the big bang theory:

a.Evidence of the expansion of the universe.
In the year 1929, Edwin Hubble observed that galaxies were generally receding from us provided the first clue that the big bang theory might be right.

(Edwin Hubble announced that galaxies found outside our own galaxy (Milky Way), as observed in the year 1929, were systematically moving away from us, at a rate proportion to their distance from us.)

b.The abundance of light elemets ( h, he, li) in the universe is almost exactly as what the big bang predicts. elements were first fused within the protons and neutrons after the big bang

(Nucleosynthesis is a term that refers to the formation of heavy elements from the fusion of lighter elements. A second after the Big Bang occurred, the temperature of the universe was extremely hot and filled with neutrons, protons, electrons, positrons, photons and neutrinos.)

c.Cosmic Microwave Background (CMB) radiation is the remnant heat leftover from the big bang.

(First predicted by Ralph Alpherin, the existence of CMB radiation was first observed by Arno Penzias and Robert Wilson. The Big Bang was theorized as a hot place and expanded. The gas within that cooled down leaving radiation of the heat that was left.)

If x = 9 units, y = 3 units, and h = 11 units, find the area

Volgvan

Answer:

297 units^2

Explanation:

Let's keep the area or volume as 'v'

$v = x \times y \times h$

So if we substitute in the values we get,

$v = 9 \times 3 \times 11$

$v = 297$

So therefore, the total volume is 297 units^2

Describe 1 environmental issue in Europe and how they affect the environment and its citizens. What can be done to correct this

Answer: Plastic Pollution

In 1950, the world produced more than 2 million tons of plastic per year. By 2015, this annual production swelled to 419 million tons and exacerbating plastic waste in the environment.

A report by science journal, Nature, determined that currently, roughly 11 million tons of plastic make its way into the oceans every year, harming wildlife habitats and the animals that live in them. The research found that if no action is taken, the plastic crisis will grow to 29 million metric tons per year by 2040. If we include microplastics into this, the cumulative amount of plastic in the ocean could reach 600 million tons by 2040.

Shockingly, National Geographic found that 91% of all plastic that has ever been made is not recycled, representing not only one of the biggest environmental problems of our lifetime, but another massive market failure. Considering that plastic takes 400 years to decompose, it will be many generations until it ceases to exist. There’s no telling what the irreversible effects of plastic pollution will have on the environment in the long run.
