What are some advantages to the use of hydrokinetic energy? What might be some disadvantages?.
Hydro-kinetic energy has advantages of being a clean, domestic, and renewable source with effective production. The disadvantages have been affected marine environment, along with water quality, and electricity on drought.
Hydro kinetic energy has been the energy produced by the movement of water bodies in the form of tides, waves, and oceanic current. The hydro-kinetic energy has been composed with high energy entrapped in the water bodies.
Some of the advantages of hydro-kinetic energy has been:
It has been a clean energy source and has been pollution free.It has been used as domestic source of energy.It has been a renewable source of energy.It has been produced by the tidal waves, thus can be produced effective and in need.Some of the disadvantages of hydro-kinetic energy has been:
Application of water bodies affects the marine environment.It has been producing low BOD and thereby affects the water quality.Conditions such as drought result in the affected electricity production.For more information about hydro-kinetic energy, refer to the link:
https://brainly.com/question/13120577
Answer:
Some advantages to using hydrokinetic energy are that it can be used without mining materials, it is not associated with waste production, and that it does not contribute to air pollution. The main disadvantage to using hydrokinetic energy is the fact that it uses waves and tides as an energy source. This technology could not be used in all locations.

Explanation:
the valence electrons of metals jump easily to a higher energy orbital when light shines on them then they all fall emiting the excess energy as light which property of metals is explained by this?
Answer:
Lustrous
Explanation:
Metals are lustrous which gives them a property of having Shiny surfaces
The valence electrons of metals jump easily to a higher energy orbital when light shines on them then they all fall emitting the excess energy as light show lustrous property of metals.
What are valence electrons?Valence electrons are defined as a negatively charged particle that can be shared or transmitted between atoms that is found in the outermost shell of an atom. Valence electrons have a crucial role in determining how an atom will behave. The electrical configurations of elements can be used to find valence electrons. The total number of valence electrons in that element is then determined by counting the number of electrons in the outermost shell.
When newly treated, polished, or broken, a material takes on a bright look and conducts electricity and heat reasonably well. Metals are typically ductile and malleable. These traits are the result of the metallic bond that connects the atoms or molecules of the metal.
Thus, the valence electrons of metals jump easily to a higher energy orbital when light shines on them then they all fall emitting the excess energy as light show lustrous property of metals.

What is the volume, in liters, of 1.4 moles of CO2 gas at STP?
Answer:

Explanation:
Please Help Will Mark Brainliest!!!
Liquid water can be separated into hydrogen gas and oxygen gas through electrolysis. 1 mole of hydrogen gas and 0.5 moles of oxygen gas is produced from 1 mole of liquid water collected in separate 10 L containers at 1 atm. Will the temperatures of the gases be equal? In one to two sentences, use the ideal gas law to explain your answer. (20 points)
Answer:
The ideal gas law specifies the mechanical behavior of ideal gases. It is capable of calculating the volume of gases produced or consumed.
In chemical equations, these equations are widely used to convert between volumes and molar quantities.
Use ideal gas law
Therefore
is the same for both So, = same for both.
When n increases, T decreases, so, n is 1 for and 0.5 for , implying that is hotter.
The temperatures of the gases will not be equal.
The ideal gas law specifies the mechanical behavior of ideal gases. It is capable of calculating the volume of gases produced or consumed. In chemical equations, this equation is widely used to convert between volumes and molar quantities. The ideal gas law states that the pressure, temperature, and volume of gas are related to each other[tex]PV=nRT[/tex]
∵V is the same for both
∴T= same for both.
When n increases, T decreases, so, n is 1 for hydrogen gas and 0.5 for oxygen gas ,implying that oxygen gas will have more temperature than hydrogen gas since its number of moles are lower than hydrogen gas.

~AH1807the bradford assay only works at low protein concentrations
Answer:
Dilute the sample
Explanation:
The statement is not entirely accurate. The Bradford assay is commonly used to determine protein concentrations in a sample.
However, it is true that the Bradford assay is more accurate and reliable for measuring protein concentrations at low to moderate levels rather than at very high concentrations.
The Bradford assay is based on the binding of Coomassie Brilliant Blue dye to proteins. The dye undergoes a color change from brown to blue when bound to proteins, allowing for the measurement of protein concentrations. At low protein concentrations, the binding of the dye to proteins is well-calibrated and results in a linear relationship between protein concentration and color intensity, making it suitable for accurate quantification.
At high protein concentrations, the binding capacity of the dye may become saturated, leading to non-linear and less accurate measurements. The excess protein can also cause interference and affect color development. In such cases, dilution or alternative protein quantification methods may be more suitable, such as the BCA assay or the Lowry assay.
Therefore, while the Bradford assay can be used to measure protein concentrations across a range of concentrations, it is generally more reliable for low to moderate protein concentrations.

Rubia was given a type of inclined plane called a ramp in her science class. Her teacher told her that the ramp should have a mechanical advantage of 3.
Rubia pulled a block up the ramp, but afterward she calculated that the mechanical advantage of the ramp was 2.8 instead of 3. Her teacher said she did not make a mistake. What did Rubia calculate?
A.
the actual operating power of the ramp
B.
the actual mechanical advantage of the ramp
C.
the ideal mechanical advantage of the ramp
D.
the ideal operating power of the ramp
Answer: B. The actual mechanical advantage of the ramp.
Explanation:
The professor saying that the ramp SHOULD have a mechanical advantage of 3 indicates that that would be the ideal mechanical advantage. Since Rubia calculated it to be 2.8, that means that it is the acutal mechanical advantage. The actual advantage will be reduced from the ieal due to things like friction.
