Comparing the two waves, wave B has a...
A) higher frequency.
B) greater amplitude.
C) shorter wavelength.
D) longer wavelength.
Answers
Answer: D) longer wavelength.
Explanation:
As far as I know, you calculate frequency on a graph using the number of peaks you can see. Since the wavelength is shorter (the distance between two peaks on the wave), the frequency should also be higher as more fit on the graph.

how do you study things that your not interested. Im studying about rocks and it isnt my type
Answers
Answer:
I say you fake it til’ you make it. You have to also train your mind to have the energy and interest in wanting to study. I’m sure lots of people hate math and I myself hate as well. I watched a video on how to study and the best way to study wether you like it or not is to pretend your teaching a class or someone. This is why alot of people find studying with others helps them do better as well. However if you have no one to study with, do the pretending method. I believe it works best :3

It's very simple student. You can study things you're not interested in only if you can discipline yourself.
As students, you usually, frequently and most of the times dislike some topics or subjects due to some reasons below:
When you don't like your teacherWhen you miss classesWhen you're lazyWhen you don't understand the your teacher's teaching methodologyWhen any of this sets in, you're likely not to have interest in a topic
Remember: that topic you don't have interest in is part of your curriculum and must be understood in order to pass your upcoming examination
Above all, the greatest key to study what you're not interested in is discipline
What is discipline?It is the act of training people to obey rules or observe good morals or behaviour.
So therefore, try as much as possible to always attend classes, like your teachers and discipline yourself to study well

Why is it easier for most metal elements to gain electrons rather than to lose them?
PROPER EXPLANATION
Answers
Because it is easier for metals to shed their valence electrons and form cations for a stable configuration, they have comparatively few chances of acquiring electrons.
The metals usually complete their octet in each reaction. The outermost electron shell often contains more electrons in metals. Metal atoms lose electrons when they interact with other non-metals because the energy of an electron in its outermost shell is very weak.
Metals often have low ionization energy because their electrons are positive in nature. Metals lose their electrons and trade them with non-metals to achieve a stable configuration.

Develop models bonds can be placed on a scale that ranges from 100% ionic to 100% covalent. Use what you know about the types of bonds that specific elements tend to form to place each of the following compounds in the correct location on the scale: CO2, N2 , NaF, H2O
Answers
Answer:
Bonds can be placed on a scale that ranges from 100% ionic to 100% covalent.
CO2: CO2 is a covalent compound, with each carbon atom sharing electrons with two oxygen atoms. Therefore, it can be placed closer to the 100% covalent end of the scale.
N2: N2 is a covalent compound, with each nitrogen atom sharing electrons with another nitrogen atom. Therefore, it can be placed closer to the 100% covalent end of the scale.
NaF: NaF is an ionic compound, consisting of a sodium cation (Na+) and a fluoride anion (F-). Therefore, it can be placed closer to the 100% ionic end of the scale.
H2O: H2O is a polar covalent compound, with the hydrogen atoms sharing electrons with the oxygen atom, but the electrons are not shared equally, therefore the oxygen atom has a partial negative charge and hydrogen atoms have a partial positive charge. Therefore, it can be placed closer to the middle of the scale, between ionic and covalent.
Overall, the scale can be represented as follows:
100% Ionic <-------> NaF <-------> H2O <-------> CO2 <-------> N2 <-------> 100% Covalent

Hello..!
There are 2 main types of ions one is an atom where the electrons are shared between the atoms. the other is an electron where one atom loses an electron to become a neutral in a charged ion, and the other atom gains the electron to become a charged lon anion.
\( \sf \red {\underline{ \underline{Explantation:}}}\)
Ions with a positive charge are known as cations. Those that are negatively charged are called anions.
¿Doubts? in the comments Greetings.
The two main types of bonds formed between atoms are ionic bonds and covalent bonds. An ionic bond is formed when one atom accepts or donates one or more of its valence electrons to another atom. A covalent bond is formed when atoms share valence electrons.

PLEASE HELP!! Phytoplankton are one of the most important parts of the food web in the Hudson river. what evidence supports the conclusion? A) The population of phytoplankton dropped sharply soon after zebra mussels invaded the river. B) The decrease in phytoplankton caused a decrease in the river's zooplankton, fish, and native mussel populations. C) The decrease in phytoplankton meant that the river's turbidity, or cloudiness decreased. D) Zebra mussels caused oxygen levels in the river to drop, partly by removing the phytoplankton that produce oxygen.
Answers
Answer:
Your answer is b
Explanation:
the answer is b because if there is no phytoplankton then there will be no fish and if you take out one part of the food chain then the whole chain comes apart. So meaning if there is no phytoplankton, then there is no fish, if there isn't any fish, then the other animals that come to eat at the river will eventually starve to death or move somewhere else to get more food.
The statement that supports the fact that phytoplankton are one of the most important parts of the food web in the Hudson river is; "the decrease in phytoplankton caused a decrease in the river's zooplankton, fish, and native mussel populations."
Phytoplankton refers to the microscopic and photosynthetic organisms found in water bodies. They are able to trap energy directly from the sun to produce their own food by photosynthesis.
If this primary productivity is hampered in the food web in the Hudson river, there will be nothing for the small fishes to and other native populations to eat and their population will begin to decrease.

Mitosis: Mitosis is a process where a single cell divides into two identical daughter cells (cell division). The major purpose of mitosis is for growth and to replace worn out cells.
Cytokinesis: Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. ... Mitosis and each of the two meiotic divisions result in two separate nuclei contained within a single cell.

The toucan uses its long beak to reach fruits and berries growing on trees in the forest. The energy stored in the fruit and berries is passed on to the toucan when it is eaten. What is the source of energy for the fruits and berries growing on the trees in the tropical forest?
A: Soil
B. Sunlight
C. Heat
D. Water
Answers
Answer:
The type of adaptations of the Toucan and Monstera Plant are physical adaptions. Both of these adapted physical characteristics help these organisms to survive. The difference in their physical adaptation is that in the Toucan, the physical characteristic helps the Toucan consume nutrients. Meanwhile, the adaptation of the Monstera Plant helps prevent harmful things such as mold.
Plants use photosynthesis to convert light into cellular energy, which allows them to make “food” out of the water and nutrients from the soil.
