Si se aplica a un muelle una fuerza de 30N provocamos que se alarguen 0.2m . Calcular la constante del resorte. Y que fuerza que habra que aplicarle para que se alargue 0.45m

Answers

Answer 1

Answer:

I. Constante de resorte, k = 150 Nm.

II. Fuerza = 67.5 Newton.

Explanation:

Dados los siguientes datos;

Fuerza, F = 30 N

Extensión, e = 0.2 m

Para encontrar la constante del resorte;

Fuerza = constante de resorte * extensión

F = ke

30 = k * 0.2

Constante de resorte, k = 30 / 0.2

Constante de resorte, k = 150 Nm

A continuación, para encontrar la fuerza para una extensión de 0,45 m;

Fuerza = 150 * 0.45

Fuerza = 67.5 Newton.

After TELOPHASE II of meiosis, what is the chromosomal makeup of each daughter cell?

Diploid, and the chromosomes are each composed of two daughter cells
Diploid, and the chromosomes are each composed of a single daughter chromosome
Haploid, and the chromosomes are each composed of a single daughter chromosome
Haploid, and the chromosomes are each composed of two daughter chromosomes

plz remember its telophase 2 not 1

Answers

Answer:

Haploid, and the chromosomes are each composed of a single daughter chromosome

Explanation:

Meiosis is a type of cell division that reduces the chromosomal number of the daughter cells by half. Meiosis produces four daughter cells, which have half of the chromosomes of the parent cell. Meiotic process occurs in two division steps i.e. meiosis I and meiosis II, which each involves four stages namely: prophase, metaphase, anaphase and telophase.

- During meiosis I, homologous chromosomes (similar but non-identical chromosomes from parent), are separated into opposite poles while

- During meiosis II, sister chromatids (replicated chromosomes) separate into opposite poles.

Based on the above explanation, after TELOPHASE II of meiosis II, each daughter cell will be HAPLOID (n), and the chromosomes are each composed of a single daughter chromosome.

Answers

Answer:

The atmosphere: is mostly made of nitrogen, protects the Earth from harmful radiation, and contains water vapor.

Explanation:

The atmosphere can be defined as the gassy wrapping covering a planet, in this case, the Earth.

The Earth´s atmosphere is composed of water vapor, N₂ (78.08%), O₂ (20.95%), Ar (0.93%), CO₂ (~0.03%), and Oz (0.01%). There are also other gases in reduced concentrations. Water vapor might reach 4% of the atmosphere near the Earth's surface. Water vapor and ozone absorb infrared radiation and are important in defining the terrestrial clime and keeping the environmental conditions needed for life. They protect the Earth from harmful radiation.

The atmosphere is composed of different layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is the most inferior layer, in contact with the Earth´s surface, composing almost 90% of the atmospheric mass.

The initial step in the formation of an aminoacyl-tRNA is Group of answer choices esterification of the tRNA activation of the tRNA by reaction with ATP activation of the amino acid by reaction with ATP interaction of the mRNA with the tRNA

Answers

Answer:

The initial step in the formation of an aminoacyl-tRNA is activation of the amino acid by reaction with ATP

Explanation:

In protein synthesis, the first step involves the formation of an aminoacyl-tRNA. This reaction is catalyzed by the the Mg²⁺-dependent enzymes known as aminoacyl t-RNA synthetases and occurs in two steps.

The first step of the reaction of the formation of an aminoacyl-tRNA is the  activation of the amino acid by the attachment of an AMP molecule formed from the hydrolysis of ATP to AMP and pyrophosphate. The aminoacyl adenylate intermediate is bound to the enzyme in this initial step. Subsequently, in the second step of the activation of the amino acid, the aminoacyl adenylate intermediate is then transferred to its specific tRNA. The pyrophosphate formed in the first step is hydrolyzed to 2 phosphate molecules by a pyrophosphatase.

The overall reaction step is illustrated below:

Amino acid + tRNA + ATP -----> aminoacyl-tRNA +AMP + 2Pi

Explanation:

the distance between two successive crests or troughs of a wave is called wavelength

The diagram shows the distance between two successive crests or troughs of a wave, and it  is called wavelength.

What is wavelength?

Typically, wavelength is measured from crest to crest or from trough to trough in transverse waves with points vibrating at right angles to the direction of their advance.

It is measured from compression in longitudinal waves with points vibrating in the same direction as their advance.

It is a property of both traveling waves and standing waves, as well as other spatial wave patterns.

Therefore, It is the distance between two successive corresponding locations of the same phase on the wave, such as two nearby crests, troughs, or zero crossings.
