Yellow light travels through a certain glass block at a speed of 3 * 108 m/s . The wavelength of the light in this glass is 3.81 * 10 - 7m . What is the frequency?
Answer:
f = 7.87×10¹⁴ Hz
Explanation:
Given data:
Speed of light = 3×10⁸ m/s
Wavelength of light = 3.81 ×10⁻⁷ m
Frequency of light = ?
Solution:
Formula:
Speed of wave = wavelength × frequency
Now we will put the values in formula.
3×10⁸ m/s = 3.81 ×10⁻⁷ m × f
f = 3×10⁸ m/s / 3.81 ×10⁻⁷ m
f = 0.787 ×10¹⁵ s⁻¹
s⁻¹ = Hz
f = 0.787 ×10¹⁵ Hz
f = 7.87×10¹⁴ Hz

Which equation best represents conservation of matter?
A 6H2O + 6CO2 → C6H12O6 + 6O2
B 6H2O + 6CO2 → C3H6O3 + 3O2
C 3H2O + 3CO2 → C6H12O6 + 6O2
D 6H2O + 10CO2 → C6H12O6 + 4O2
Answer:
A 6H2O + 6CO2 → C6H12O6 + 6O2
Explanation:
The law of conservation of matter states that matter can neither be created nor destroyed in a system. In other words, when elemental matter undergoes a reaction, the amount of elements used must be equal the amount produced.
The equations in this question depicts the overall photosynthetic process where CO2 combines with H2O to produce C6H12O6 and O2. In order for this equation to obey the "conservation of matter", each individual element must be equal on both the reactant and the product side i.e. the equation must be balanced.
The equation that fulfills this is:
6H2O + 6CO2 → C6H12O6 + 6O2
Hence, it correctly describes the conservation of matter.

During weeks 17-20, quickening occurs, which is when the
A. fetus' sense of hearing is developing at a rapid pace
B. mother can hear the fetus' heartbeat with headphones
C. fetus' heart rate increases to 150 beats per minute
D. mother is able to feel the fetus move inside her womb
A: D. mother is able to feel the fetus move inside her womb
E: ED20 CA-Psychology
During weeks 17-20, quickening occurs, mother is able to feel the fetus move inside her womb. The correct option is D.
What is gestation period?It is measured in weeks, beginning with the first day of the woman's last menstrual cycle and ending with the current date.
A normal pregnancy can last between 38 and 42 weeks. Premature babies would be those born prior to actually 37 weeks. Postmature infants are those born after 42 weeks.
It is common in mammals, but it also occurs in some non-mammals. Mammals can have one or more gestations at the same time during pregnancy, as in a multiple birth.
Pregnancy is calculated from the first day of the woman's last period, rather than the date of conception, which usually occurs two weeks later.
Quickening occurs during weeks 17-20, and the mother can feel the fetus move inside her womb.
Thus, the correct option is D.

7. Pick two of Earth's spheres (biosphere, atmosphere, geosphere, hydrosphere), and draw a model showing how these two systems interact. Your model should show components of these systems, at least one way these components interact, and inputs and outputs that move from one system to another.
Answer:
alright, the answer is biosphere
Explanation:
The earth sphere that is the biosphere is a product of the interaction of atmosphere, lithosphere, and hydrosphere. Together they are called as the geosphere.
All these spheres interact with one another and their interaction leads to life on earth. The atmosphere consists of the most essential gases known to maintain temperature and sustain life on earth such as oxygen. The other component knows as the hydrosphere has water which when interacts with air through the processes of evaporation, condensation, and precipitation all driven by the solar mechanisms.Thus the air and water cycle interaction leads to the input and output of energy in the ecosystem.

describe the effects that enzymes can have on substrates
Answer:
Enzymes bind with chemical reactants called substrates there may be one or more substrates for each type of enzyme I beleivedepending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products the enzyme's active site binds to the substrate.
Explanation:
Hope this helps.
Answer:
When an enzyme binds its substrate, it forms an enzyme-substrate complex. This complex lowers the activation energy of the reaction and promotes its rapid progression by providing certain ions or chemical groups that actually form covalent bonds with molecules as a necessary step of the reaction process

What type of protist is an amoeba and how does it move?
Answer:
Explanation:
An amoeba is a classification of protist (single-celled eukaryotic organism that is neither plant, animal, bacteria, nor fungus) that are amorphous in shape. They move via forming 'feet-like' pseudopodia, which are also used for feeding.
Answer:
Explanation: Amoeba and sarcodines are examples of protists that move by pseudopods. Some animal-like protists move by using cilia. Cilia are hair-like projections that move with a wave-like pattern. The cilia move like tiny oars to sweep food toward the organism or to move the organism through water.

Which describes electrons?
A.) Electrons move at very fast speeds inside the nucleus of an atom.
B.) Electrons are stationary outside of the nucleus of an atom.
C.) Electrons are stationary inside the nucleus of an atom.
D.) Electrons move at very fast speeds around the nucleus of an atom.
The answer is D.) Electrons move at very fast speeds around the nucleus of an atom.
The option that best describes electrons is as follows:
Electrons move at very fast speeds around the nucleus of an atom.Thus, the correct option is D.
What is Electron?An Electron may be defined as a negatively charged subatomic particle that is significantly found in all atoms and functions as a primary carrier of electricity mostly in solids.
The electrons are always revolving around the nucleus of an atom, while protons and neutrons are localized in the center of an atom known as the nucleus.
Electrons are negatively charged subatomic particles and due to this, they generate an electric field that exerts an attractive force on a particle with a net positive charge and induces a repulsion force on a particle with the same negative charge.
Therefore, the option that describes the electrons is that they move at very fast speeds around the nucleus of an atom. Thus, the correct option for this question is D.

can somebody help me make a claim , evidence and reasoning on “Do you think school days should be made longer?
i need it now please help me
Answer:
i don't think so school days must be shorter and practical session must be longer theory is boring
Answer:
I think school days should not be made longer as this would impact the students mental health. Students attend school for approximately 7 hours a day in which they learn new content, this time being increased would cause stress and burden on students as classes would be longer and time spent at home would be less. Students need enough time to rest and relax their minds, as well as, spend time with their families. If extending school hours, students will have less time for self-care and family time which can lead to depression and loneliness. However, there are benefits of extending school hours such as more time to finish homework. But, a student's health must come first. In conclusions, school days should not be made longer.

Dear water,
I love you, You are highly special to me as you are attracted towards you own molecules(cohesion) and others as well(adhesion). Your density is so compatible that its used as standard for almost all reactions. You are neither acidic nor basic and you hold a PH of 7. You can also be used as temperature moderators as you have the highest specific heat capacity. You hold special bonds with selected molecules and form hydrogen bonding, Polarity of you molecules makes you bend just like ammonia and your solubility is exceptional as you are considered a good solvent these qualities of your makes me love you even more.
