What do supernova have to do with heavy elements?
Answer:
When a star dies, it is called a supernova. A supernova contains massive amounts of energy, and the hydrogen and helium that was originally in the star turns into heavier elements ranging from oxygen to iron to gold.
Let me know if this helps!
Answer:
Read Below
Explanation:
During the supernova nucleosynthesis, the r-process creates heavy isotopes, which decay after the event to the first stable isotope, thereby creating the neutron-rich stable isotopes of all heavy elements. The neutron capture occurs in high neutron density with high-temperature conditions.

Electromagnetic Spectrum Lab Report
if you've done this assignment or know what im talking about please helps me! if you get it correct i will give you brainliest!!!!!!!!!!!!!
Objectives(s):
In your own words, what is the purpose of this lab?
Hypothesis:
In this section, please include the predictions you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.
Procedure:
The materials and procedures are listed in your virtual lab. You do not need to repeat them here. However, you should note if you experienced any errors or other factors that might affect your outcome. Using your summary questions at the end of your virtual lab activity, please clearly define the dependent and independent variables of the experiment.
The dependent variable is the one that changes as a result of the independent variable. The spectrum emitted by the unknown celestial object in this situation.
What is the electromagnetic spectrum?The electromagnetic spectrum refers to the variety of frequencies (the spectrum) of electromagnetic radiation, as well as the wavelengths and photon energies associated with each frequency.
The goal of the electromagnetic spectrum experiment is to determine what elements are present in the atmospheres of the planets and moons by examining their absorption spectrums.
The electromagnetic spectrum encompasses electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz,
The frequency corresponds to wavelengths ranging from thousands of kilometers to a fraction of an atomic nucleus's size.
The electromagnetic waves within each frequency band are given various names, starting at the low frequency (long wavelength) end of the spectrum.
Hence the dependent variable is the one that changes as a result of the independent variable.

A wave is traveling at the speed of light. If it has a frequency of 4 x 10^15 Hz, what is its wavelength?
Answer:
7.5x10-^8m
Explanation:
the formulae is v=fh ,where f is frequency
h is wavelength
hence wavelength=v/f
since the speed of light is 3x10^8
then the wavelength =3 x 10^8/4 x 10^15
=7.5x10^-8m

What is electromagnetic spectrum ?The electromagnetic spectrum encompasses electromagnetic waves with frequencies ranging from less than one hertz to greater than 1025 hertz, corresponding to wavelengths ranging from thousands of kilometres to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are given different names; beginning at the low-frequency (long-wavelength) end of the spectrum, these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

WHAT IS THE DENSTY OF ALL THE LAYER IN THE ATMOSPHERE
Answer:
The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. Almost all weather is in this region.
Explanation:
The troposphere contains roughly 80% of the mass of Earth's atmosphere. The troposphere is denser than all its overlying atmospheric layers because a larger atmospheric weight sits on top of the troposphere and causes it to be most severely compressed.

Why can scientists ignore the gravitational force when
studying the physies of an atom?
Answer:
When studying atoms, scientists can ignore the Gravitational force between charged particles that make up the atoms because it is many millions of times smaller than other forces in the atom. Explanation: Scientists can ignore the gravitational force because the gravitational force is considered to be negligible as compared to the other forces due to its smaller value.

Explain How do the attractions between particles in a fluid determine viscosity?
Answer: Viscosity is due to particle mass, particle shape, and the strength of the attraction between the particles of a liquid. In general, the stronger the attractive forces between particles, the higher the viscosity. For many liquids, viscosity decreases when heat is applied.
