The frequency of the musical note F3 is 1.85 102 hertz. What is its period?
A 5.40 x 10-3seconds
B. 1.05 x 10-3 seconds
C. 3.09 x 10-3 seconds
D. 5.31 x 10-1 seconds
Answers
Answer: 0.0054 s
Explanation: There is an inverse relation between the frequency and the period of a wave (a sound wave in this case):
T=1/F
Where f = 1.85 (10)² H z
Hence : T = 1/1.85 (10)² H z T =0.0054s
1. A student predicted the reaction between hydrogen and oxygen gas would yield 125
mL of water. However, after measuring the water formed in the reaction, the
student determined that only 110mL of water was actually formed. What is the
percent yield of this reaction?
Answers
Answer:
88%
Explanation:
percent yield is the actual yield divided by the theoretical (predicted) yield, then multiplied by 100 to get a percentage.
110/125 = 0.88
0.88 x 100 = 88%

Choose ALL that apply for NEAP tides Moon and Sun are at right angles to the Earth gravity of the Sun and Moon work against each other Moon, Sun, and Earth are in alignment smaller than normal range of highs and low tides
Answers
Answer:
i think it is..... smaller than normal range of highs and low tides
Moon and Sun are at right angles to the Earth
Explanation:
Moon and Sun are at right angles to the Earth and gravity of the Sun and Moon work against is the right statement about NEAP tides.
What are tides?Tides are the cyclic deformation of water body occur due to external gravitational force.
NEAP tides are also known as small tides as their heights are not very much and this is occur due to opposite attraction of water towards the gravity of the sun and moon. As sun and moon are present in the right angle direction with respect to the earth.
Hence, option (1) & (2) is correct, i.e. gravity of sun and moon is opposite and they are present at the right angle to the earth.

Answers
Answer:
A. Antibiotic resistance can sometimes be shared among bacteria.
B. Mutation can cause antibiotic resistance.
D. Antibiotics killing bacteria while allowing mutated bacteria to live is an example natural selection.
Explanation:
Identifying: Archaea have cell walls that lack peptidoglycan and have membranes that enclose lipids with hydrocarbons rather than fatty acids (not a bilayer). ... Bacteria: cell membrane contains ester bonds; cell wall made of peptidoglycan; have only one RNA polymerase; react to antibiotics in a different way than archea do.
Hope this helps, I reported some answer that was absurd, not applicable, incomplete and confusing
Mutation can cause antibiotic resistance, Bacteria that become resistant are an example of evolution. Antibiotics killing bacteria while allowing mutated bacteria to live is an example natural selection The correct options are B, D, and C.
What are archaebacteria and bacteria?Archaea, like bacteria, lack interior membranes but have a cell wall and swim with flagella.
Archaea differ from bacteria in that their cell wall lacks peptidoglycan and their cell membrane contains ether linked lipids rather than ester linked lipids.
The dispersion of antibiotic resistance in pathogenic bacteria is a simple and elegant example of natural selection at work.
Bacteria can develop antibiotic resistance through mutations that alter antibiotic cellular targets or by acquiring dedicated resistance genes from other bacteria.
Antibiotic resistance can be caused by mutation; bacteria that become resistant are an example of evolution. Natural selection is demonstrated by antibiotics killing bacteria while allowing mutated bacteria to live.
Thus, B, D, and C are correct options.

Los alcoholes de cadenas largas presentan ________ puntos de ebullición. Asimismo, éstos al tener ________, el punto de ebullición disminuye
Answers
Answer:
Los alcoholes de cadena larga tienen altos puntos de ebullición. Además, cuando tienen ramificación, el punto de ebullición disminuye
Explanation:
El punto de ebullición de un alcohol se ve afectado, las interacciones dipolo-dipolo, las fuerzas de dispersión de van der Waals y los enlaces de hidrógeno.
Las fuerzas de las interacciones dipolo-dipolo y los enlaces de hidrógeno son más o menos las mismas en la serie de alcohol en serie, sin embargo, a medida que aumenta la longitud del alcohol, las fuerzas de dispersión de van der Waals aumentan debido al aumento de la atracción dipolo-dipolo.
Sin embargo, a medida que el alcohol se vuelve más ramificado, el área de la superficie aumenta, lo que disminuye las fuerzas de van der Waals, de modo que se requiere menos fuerza para separar las moléculas y hervir una muestra del alcohol.
Por tanto, los alcoholes de cadena larga tienen puntos de ebullición elevados. Además, cuando tienen ramificación, el punto de ebullición disminuye.

A sample of sodium hydroxide of volume 13.9 mL was titrated to the stoichiometric point with 20.6 mL of 0.209 M HCl(aq). What is the initial molarity of NaOH in the solution? Answer in units of M
Answers
Answer:
Explanation:
NaOH + HCl = NaCl + H₂O
1 mole 1 mole
moles of hydrogen chloride reacted = .0206 x .209
= 4.3054 x 10⁻³ moles .
moles of sodium hydroxide reacted will be same = 4.3054 x 10⁻³ moles
Let x be the molarity of NaOH
13.9 mL of x molarity will contain
.0139 x moles
.0139 x = 4.3054 x 10⁻³
13.9 x 10⁻³ x = 4.3054 x 10⁻³
x = .3097 M .
= .31 M .

How is energy converted in a hydroelectric plant?
The potential energy of water is converted to electrical energy when water flows past a generator.
The kinetic energy of water turns turbines; the mechanical energy of the turbines turns the generator, which produces electrical energy.
The kinetic energy of water is converted to electrical energy when water flows down the dam's channel and into the transformer.
The potential energy of water turns the generator's turbines, which results in the production of electrical energy.
Answers
Answer:
Energy is converted in a hydroelectric plant as follows;
The kinetic energy of water turns turbines; the mechanical energy of the turbines turns the generator, which produces electrical energy
Explanation:
The water in an hydroelectric plant is given potential energy by building an artificial dam to raise the height of the water above the turbine
The high potential energy of the water is converted to kinetic energy which provides the power that turns the turbine transforming the kinetic energy of the water into rotational kinetic energy of the turbine by conservation of mechanical energy;
The shaft connected between the turbine and the generator, turns the generator by the mechanical energy of the turbine and as the generator turns in a magnetic field, electricity is produced by magnetic induction according to Faraday's law.
