Answer:  44.8\°

Explanation:

We have a right triangle with sides AB, BC=5cm and AC=13cm (the hypotenuse). Let's apply the Pithagorean Theorem to find AB:

AC^{2}=AB^{2} + BC^{2}  (1)

AB^{2}=AC^{2} - BC^{2} (2)

AB^{2}=(13cm)^{2} - (5cm)^{2} (3)

AB=12cm (4)

Now that we know the value of each side of the triangle, we will use the trigonometric function sine to find the angles C and A (angle B is 90\° remembering we are talking about a right triangle):

For angle C:

sinC=\frac{Oppositeside}{Hypotenuse}

sinC=\frac{12}{13}  (5)

C=sin^{-1}(\frac{12}{13})  (6)

C=67.38\°  (7)

For angle A:

sinA=\frac{5}{13}  (8)

A=sin^{-1}(\frac{5}{13})  (9)

A=22.62\°  (10)

Calculating the difference between both angles:

C-A=67.38\°- 22.62\°

C-A=44.76\° \approx 44.8\°

Big Bang nucleosynthesis yielded primarily a. light elements with atomic numbers less than 5. b. all 92 naturally occurring elem
sveticcg [70]

Answer:

The correct answer out of the four given options is

option a. light elements with atomic numbers less than 5

Explanation:

Big Bang nucleosynthesis, abbreviated as BBN, also known as primordial nucleosynthesis took place after the Big Bang for about 10 s to 20 minutes and resulted in the yield of isotopes of helium-4  (^{4}He), helium-3 (^{3}He) which accounts for most of the world's helium, other isotopes of hydrogen in small amounts like deuterium (D or^{2}H) and lithium isotope, lithium-7(^{7}Li) in small amount.

Apart from these stable nuclei, it also yielded two radio-active isotopes: tritium(^{3}H) and beryllium-7(^{7}Be) which due to their unstability later decayed into (^{7}Li) and (^{3}He).

All of these isotopes are of light elements with atomic number less than 5.

C -- Explain the Big Bang Theory using astronomical evidence such as light spectra, motion
-Dominant- [34]

Answer:

Regardless of its name, the Big Bang theory found widespread acceptance for its unparalleled ability to explain what we see. The balance of light with particles like protons and neutrons during the first 3 minutes, for instance, let early elements form at a rate predicting the current amounts of helium and other light atoms.

"There was a small window in time where it was possible for nuclei to form," said Glennys Farrar, a cosmologist at New York University. "After that, the universe kept expanding and they couldn't find each other, and before [the window] it was too hot."

A cloudy plasma filled the universe for the next 378,000 years, until further cooling let electrons and protons form neutral hydrogen atoms, and the fog cleared. The light emitted during this process, which has since stretched into microwaves, is the earliest known object researchers can study directly. Known as the cosmic microwave background (CMB) radiation, many researchers consider it the strongest evidence for the Big Bang.
