Given the speed of light (3.00×108 m/s) and a wavelength 4.3×10−7 m, what is the frequency?
Explanation:
Given :
speed of light (c) =
[tex]3.00 \times 108m/s[/tex]
wavelength (λ) =
[tex]4.3 \times {10}^{ - 7} \: m[/tex]
Equation :
c = λv
v = c/λ
[tex]v = \frac{3.00 \times {10}^{8} }{4.3 \times {10}^{ - 7} } [/tex]
Simplify
[tex]v = 6.976744186 \times {10}^{14} [/tex]

Bats have oversized ears, which help the bats use sound waves to detect the motion of their prey. Which example of the characteristics of life is most similar?
Answer:
option B = A rat hides in its hole when it sees an approaching predator.
Explanation:
In order for any organisms, whether plants or animals to be able to keep being alive they have to develop a/some functions or abilities which is going to aid in their battle battle for survival, this concept is known as the Adaptive features of organisms.
From the question above, it can be seen that the oversized ears in bats is an adaptive features for them to get their food: as it helps them to use sound waves to detect the motion of their prey.
Unlike the bats, the rats adaptive features is to have a good running legs. This will help them to avoid getting eating by predators.

Potasyum-40 küçük atom numaralı doğal radyoaktif birkaç element izotopundan biridir ve doğada K izotopları içerisindeki bolluk yüzdesi %0,012'dir. 1,65 mg K/mL içeren bir bardak sütü içtiğiniz zaman kaç tane 40K atomu yutmuş olursunuz? (1 Bardak süt 225 mL, K: 39,10 g/mol)
Answer:
6.707 × 10¹⁷
Explanation:
From the information given:
40 ^ K kütlesi = sütteki K kütlesi × 40 ^ K / 100 kütle yüzdesi
nerede;
sütteki K kütlesi = 1.65 mg of K/mL × 225 mL = 371.25 mg of K
∴
40 ^ K kütlesi = 371.25 × 0.012/100
40 ^ K kütlesi = 0,04455 mg = 4.455 × 10⁻⁵ grams
40 ^ K mol sayısı = 40 ^ K kütlesi / molar kütle
= 4.455 × 10⁻⁵/40
= 1.11375 × 10⁻⁶
Son olarak, 40 ^ K = mol × Avogadro sayısı atomları
= 1.11375 × 10⁻⁶ × 6.022 × 10^23
= 6.707 × 10¹⁷

Answer:
A. Instructions for inherited traits
Explanation:
Your traits (what makes who you are) are from your DNA, and the DNA sends instructions on how your body preforms to use/inherit those traits.
I don’t know a lot about DNA, but this is the best information I can provide.

In a group of rats, some individuals have a normal-sized body and others have a dwarf body. In this group, the gene for the body size trait has two alleles. The allele B is for a normal-sized body, and the alleles is for a dwarf body
Answer:
n a group of rats, some individuals have a normal-sized body and others have a dwarf body. In this group, the gene for the body size trait has two alleles. The allele for a normal-sized body (B) is dominant over the allele for a dwarf body (b).
Squeaky, a rat from this group, has a dwarf body.
Based on Squeaky's phenotype for the body size trait, which of the following could be Squeaky's genotype for the body size gene?

Model A shows the three-dimensional shape of the molecule, but Model B does not. Model A shows the number of atoms of each element in the molecule, but Model B does no
Answer:the answer is c babes
Explanation:
I hope I could help y’all
Have a nice day
Or whatever day u want LMA0 it’s not up to me. Ight peace loves
Model A is better than Model B as Model A shows the three-dimensional shape of the molecule, but Model B does not. The correct option is c.
What are molecules?The smallest particle of a substance possesses all of its physical and chemical properties. One or more atoms make up a molecule.
Knowing the molecular weights of the molecules allows us to calculate their sizes. The molecular weight of a molecule is the sum of the atomic weights of the atoms in the molecule.
The relative atomic mass of particles determines their size. Particles with a higher relative atomic mass weigh more than particles with a lower relative atomic mass. Larger atoms have heavier iotas and a larger relative atomic mass.
Therefore, the correct option is c, Model A shows the three-dimensional shape of the molecule, but Model B does not.

Elements in a ___ on the Period Table of Elements have similar chemical characteristics and properties.
What type of reaction will occur with the following reactants?
CaS + NaCl -->
A) double replacement
B) decomposition
C) synthesis
D) single replacement
Answer:
A) double replacement
Explanation:
Chemical equation:
NaCl +CaS → Na₂S + CaCl₂
Balanced chemical equation:
2NaCl +CaS → Na₂S + CaCl₂
The given reaction is double replacement reaction in which cation and anions of each reactant exchange with each other.
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AD +CB
Other options are incorrect because,
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
AB → A + B
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Decomposition reaction:
It is the reaction in which one reactant is break down into two or more product.
AB → A + B
WHAT DOES THE MASS OF AN OBJECT MEASURE HURRYYYYYYYYYYYYYYYYYYYYY
Answer:
object's inertial property
Explanation:
The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.

Tenemos un cuerpo de 40 g cuya densidad es 1,24 g/mL y otro objeto de 70 g con una densidad de 0,96 g/mL. Si introducimos cada uno en un recipiente con agua, ¿en qué caso subirá más el nivel de líquido?
Answer:
El nivel de líquido subirá más al introducirse el objeto de 70 g.
Explanation:
El nivel de líquido subirá más con el objeto que tenga mayor volumen.
Por lo tanto vamos a calcular el volumen de ambos objetos, usando la definición de densidad:
Densidad = Masa / VolumenSi despejamos Volumen:
Volumen = Masa / DensidadAhora usamos esa ecuación y calculamos los volúmenes:
Objeto 1 ⇒ 40 g ÷ 1,24 g/mL = 32,26 mL Objeto 2 ⇒ 70 g ÷ 0,96 g/mL = 72,92 mLPor lo tanto el nivel de líquido subirá más con el segundo objeto.
