Answer:
Constante de resorte, k = 19.745 N/m
Explanation:
Dados los siguientes datos;
Masa, m = 2 kg
Periodo, T = 2 segundos
Para encontrar la constante del resorte, k;
[tex] Period, \; T = 2 \pi \sqrt {\frac {m}{k}} [/tex]
Dónde;
T es el período. m es la masa del objeto. k es la constante del resorte.Haciendo k el tema de la fórmula, tenemos;
[tex] k = \frac {(2 \pi )^{2}m}{T^{2}} [/tex]
Sustituyendo en la fórmula, tenemos;
[tex] k = \frac {(2 * 3.142)^{2} * 2}{2^{2}} [/tex]
[tex] k = \frac {6.284^{2} * 2}{4} [/tex]
[tex] k = \frac {39.49 * 2}{4} [/tex]
[tex] k = \frac {78.98}{4} [/tex]
Constante de resorte, k = 19.745 N/m
The frequency of a wave does not change as it passes from one medium to another.
What will most likely happen if a light wave moves from the air into a solid?
O The wavelength of the light wave will increase.
O The speed of the light wave will decrease.
O The wavelength of the light wave will remain the same.
O The speed of the light wave will remain the same.
Answer:
The speed of the light waves will decrease
The frequency of a wave does not change as it passes from one medium to another.The wavelength of the light wave will increase. Thus, option A is correct.
What is a frequency table?The columns of the frequency table are two. The categories of the data are listed in the first column. The frequency of each category, or the number of the data values in the category, is listed in the second column.
The distribution of the observations based on a variable's possible values is shown in a frequency table. To understand the alternatives appear more or less often in the dataset, frequency tables are the useful. This has been considered as useful for better understanding each variable and determining whether or not variables need to be recorded.
Therefore, the frequency table has been just a two-column "t-chart" or table that lists all of the potential outcomes and their corresponding frequencies as seen in a sample.

What function do cones have?
cones help with near nearsightedness
cones help with night vision
cones help with far sightedness
cones help with color distinction
Answer:
CONES HELP WITH COLOR DISTINCTION
Explanation:
Cone cells, or cones, are one of the two types of photoreceptor cells that are in the retina of the eye which are responsible for color vision as well as eye color sensitivity; they function best in relatively bright light, as opposed to rod cells that work better in dim light.

Which of the following types of micro organisms are the most beneficial to other organisms in an ecosystem
Answer:
Bacteria.............
Put the following in order from smallest to largest.
- protein
- eukaryotic cell (has nucleus)
- virus (NOT alive)
- prokaryote (bacteria, no nucleus)
Answer:
Protein → virus → prokaryotic cell → eukaryotic cell
Explanation:
This question is asking to place the following components of organisms in an ascending order of magnitude i.e. from smallest to largest.
- Proteins are macromolecules that are found in living cells where they serve different functions. Since they are found inside cells, they are the smallest on this list.
- Viruses are microorganisms considered to be non-living because they do not show characteristics of living things. Viruses are pathogenic organisms that attack living cells. They are the smallest microbes found having sizes in nanometers (nm).
- Prokaryotes are group of organisms with no nucleus e.g bacteria. They possess cells that are smaller than that of eukaryotes.
- Eukaryotic cells i.e. cells with nucleus, have the biggest size of any cell. Hence, they are the largest in the list.
Based on the above description, the ascending order of magnitude is as follows: Protein → virus → prokaryotic cell → eukaryotic cell

which type of feature forms suddenly where intense compression deforms the rock area
Answer: The options are not given, here are the options gotten from another site.
A. volcano
b. normal fault
C. folded layers
D. reverse fault
The correct answer is Reverse fault.
Explanation:
This is because Reverse fault is caused by compressional stress which means rocks pushing over each other. It is the opposite of normal fault.
Reverse faults are exactly the opposite of normal faults.which occur when the hanging wall rises above and it is also relative to the footwall. Reverse faults plane are vertical and occur in areas with compression (squishing).

Case summary
Diagnosis
Using Anthony's symptoms and initial lab results, describe how you diagnosed that the
problem was kidney failure.
Treatment Goals
Describe the treatment goals for dialysis.
Answer:
Through symptoms.
Explanation:
We diagnosed the problem was a kidney failure due to the decreased urine output , swelling in your legs, ankles or feet, shortness of breath, fatigue, confusion, Nausea and Weakness. The main symptom is the swelling in legs, ankles or feet that tells about kidney failure. The treatment goal of Hemodialysis is to filter waste products and water from your blood. I works just like the kidneys. This treatment is used when the kidney fails to filter waste materials inside the body.
Usually for the initial diagnosis of possible renal failure, there are complaints of pain in the lower back and little urine.
What is dialysis and how does it work?Hemodialysis is the procedure by which a machine filters and cleans blood, doing some of the work that the diseased kidney cannot do. The procedure removes harmful waste from the body, such as excess salt and fluids.
Among the tests that make the diagnosis of acute renal failure are:Measurements of urine outputUrine testsBloodtestsImaging tests, such as ultrasound and CT scanRemoval of a kidney tissue sample for testing (biopsy).With this information, we can conclude that normally for the initial diagnosis of possible renal failure, there are complaints of pain in the lower back and little urine.

which nutrients are present in solution x?
Consider the 4 foods in order of the percent by mass of proteins, from lowest to highest. From food to food, as the percent by mass of proteins increased, the mass of food remaining at 28 hr: 1 point A. increased only. B. decreased only. C. increased and then decreased. D. decreased and then increased.
Answer:
B. decreased only
Explanation:
If you look at the table 1 and order the foods by the percent of protein, and after you take a look at the graph, you'll see that the bigger the percentage of protein, less food remains.

Select all the correct answers.
When people run quickly, they can sweat profusely. Their muscles undergo movement, and the loss of energy takes place. Based on this description, in which two ways is energy conserved when people run?
1. Heat energy is released from the body to the surroundings.
2. Heat energy is taken from the surroundings to the body.
3.Chemical energy is converted to mechanical energy that’s used for muscle movements.
4.Radiant energy is converted to mechanical energy that’s used for muscle movements.
5.Heat energy is converted to mechanical energy that’s used for muscle movements.
When we run, we sweat, which means we're getting hotter and hotter and our bodies need to cool down, which they do through transpiration (sweating). If we need to cool down, we need to release the heat that is in our bodies.
To run, we also need to move our muscles, which requires a specific type of energy, called mechanical or kinetic energy, which is the "energy of movement". In our bodies, we don't store that type of energy though, so we have to convert chemical energy to mechanical energy.
Answers:
⭕Heat energy is released from the body to the surroundings.
⭕Chemical energy is converted to mechanical energy that’s used for muscle movements.
Answer:
Heat energy is released from the body to the surroundings.
Chemical energy is converted to mechanical energy that’s used for muscle movements.

During the process shown above, the two strands of one DNA molecule are unwound. Then, DNA polymerases add complementary nucleotides to each strand which results in the formation of two identical DNA molecules.
\
Answer:
This question is incomplete as it lacks image, however, it can be answered based on the description. The complete part of the question is:
" This process is known as dna _______. A.) transcription B.) translation C.) cloning D.) replication
The answer is D. replication
Explanation:
DNA replication is the process whereby a DNA molecule is duplicated to form to identical copies of itself. The process of DNA replication is very pivotal and must occur prior to any cell division.
This process follows the semi-conservative model in which the double-stranded DNA molecule unwounds into two separate single strands. The single strands are then used as template for the synthesis of another complementary strands by DNA polymerase enzyme. At the end, the two DNA molecules are identical in base sequence.
