Scientific Definition of Mass:

Mass is the quantity of inertia (resistance to acceleration) possessed by an object or the proportion between force and acceleration referred to in Newton's Second Law of Motion (force equals mass times acceleration). In other words, the more mass an object has, the more force it takes to get it moving.

Answers

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]

Answers

Answer:

The lamp rattles because close resonant frequency.

Explanation:

The phenomenon of increased amplitude is known as resonance when the frequency of a periodically applied force is equal to or close to the natural frequency of the system it affects. When a resonant frequency oscillating force is applied to a dynamic system, the system oscillates with greater amplitude than when the same force is applied at non-resonant frequencies.

Resonant frequencies or resonance frequencies of the system are frequencies when the response amplitude is at a relative maximum. Due to the storage of vibrational energy, small periodic stresses at a resonance frequency of the system can cause significant amplitude oscillations in the system.

Thereforee, the lamp rattles because close resonant frequency.

Answers

Answer:

A. Unicellular prokaryotes that live in dust. Monera.

B. Unicellular eukaryotes that line in pond water. Protist.

C. Multicellular eukaryotes that live all over the planet and consume food. Animals.

D. Unicellular prokaryotes that live in volcanic ash. Monera.

E. Multicellular eukaryotes that have cell walls and are heterotrophic. Fungi.

F. Multicellular eukaryotes that have cell walls and are autotrophic. Plants.

Explanation:

The 5 kingdoms are a way of classifying all living organisms on our planet, as each species inside a kingdom shares similarities with the other species in it.

Monera kingdom includes all of the prokaryotic organisms that exist, which includes bacteria and archaea. These beings are characterized by lacking a nucleus and membrane-bound organelles and having one single circular chromosome that is found in the center of the cell. They are unicellular. Example: escherichia coli.

Protists are the most primitive eukaryotes that exist, most of them are unicellular and microscopic, but possess a nucleus and specialized organelles like the rest of the eukaryotes have. Example: yeasts.

Fungi and Plants are quite similar, they are multicellular eukaryotes that have cell walls. Their main difference relies on the way they obtain nutrients: fungi are heterotrophs, they feed off living things; plants, however, are autotrophs and realize photosynthesis (they do not need to feed). Fungi and Plants also reproduce differently: fungi reproduce through spores; plants can reproduce sexually or asexually. Fungi example: amanita; plant example: cactus.

Animals are multicellular eukaryotic organisms that reproduce sexually and are heterotrophs (some feed off plants, some feed off other animals). They are characterized by their ability to move. Example: horse.

Explanation:

This question is describing the blood vessels that make up the circulatory system. The blood vessels with their accurate description are as follows:

- ARTERIES: Arteries are the most elastic and thick-walled blood vessels that functions to carry blood away from the heart using great pressure. Arteries are muscular, flexible tubes that carry oxygenated blood away from the heart to the arterioles.

- VEINS: Veins are blood vessels that carry deoxygenated blood back to the heart. Veins have a thin wall and are less elastic in comparison with arteries.

- CAPILLARIES: Capillaries are smallest blood vessels designated to connect the smaller arteries or arterioles to venules. They are also thin-walled.

- ARTERIOLES: Arterioles are small arteries or branches of an artery that connects the arteries to capillaries. Arterioles deliver blood to capillaries.

- VENULES: Venules are tiny veins or branches of a vein that connects the veins to the capillaries. Venules deliver blood from capillaries to veins.

"Draw a pedigree for hitchhiker’s thumb. Your pedigree should cover at least two generations and include both dominant and recessive forms of the trait. Label the pedigree with genotypes, using the letter H to represent the dominant allele for the trait and the letter h to represent the recessive allele."


I'm confused on the part about having two generations. How do I set up the pedigree?

Answers

Answer and Explanation:

First, you need to know how to interpret a pedigree representation.

Family members

→ Individuals are represented with geometrical figures.

→ Males are squares

→ Females are circles

Trait/Phenotype

→ Healthy/normal/not affected  individuals are represented with empty figures

→ Affected/mutated individuals are represented with solid black figures

Generations

→ Each file is represented with a roman number, indicating the Generation.

 

Now, what we need to do is to draw a pedigree for a hitchhiker’s thumb. We know that this is an autosomal dominant trait, which we will represent with an H. No hitchhiker's thumb is the recessive trait, and it will be represented with an h.

Our pedigree should cover at least two generations and include both dominant and recessive forms of the trait.    

We can cross two heterozygous individuals, Hh, who are the first generation in our pedigree. This cross will result in a woman and a man with No hitchhiker's thumb, another man with a hitchhiker's thumb, HH, and another woman with a hitchhiker's thumb, Hh. These individuals will represent the second generation in the pedigree. Finally, we can cross the man with No hitchhiker's thumb, hh, with a woman who does not have a hitchhiker's thumb either, hh. And the woman with a hitchhiker's thumb, Hh, with a man with a hitchhiker's thumb, HH. The result of these crosses will be the third generation.

The representation would be like following,

I → First-generation: First cross

Man Hh (1)  Woman Hh (2)

II → Second-Generation: F1 and second crosses

Man hh (3)  x    Woman hh (4)Woman hh (5)Man HH (6)Woman Hh  (7) x   Man HH (8)

III → Third-Generation:

A boy (9) and a girl (10) hhA girl (11) HH

You will find this pedigree in the attached files. In this example, we included three generations. The first one belongs to the grandparents, the second one to parents, aunts/uncles, and the third one to grandchildren.  

If you draw another pedigree, remember to include

the figures representing males and females, color and H/h representing the phenotype, Roman numbers representing the generations, and optional, numbers naming each member.

It stretches southward across the largest and northernmost state in the United States, ending at a remote ice-free seaport village nearly 800 miles from where it begins. It is massive in size and extremely complicated to operate. The steel pipe crosses windswept plains and endless miles of delicate tundra that tops the frozen ground. It weaves through crooked canyons, climbs sheer mountains, plunges over rocky crags, makes its way through thick forests, and passes over or under hundreds of rivers and streams. The pipe is 4 feet in diameter, and up to 2 million barrels (or 84 million gallons) of crude oil can be pumped through it daily. Resting on H-shaped steel racks called "bents," long sections of the pipeline follow a zigzag course high above the frozen earth. Other long sections drop out of sight beneath spongy or rocky ground and return to the surface later on. The pattern of the pipeline's up-and-down route is often determined by the harsh demands of the arctic and subarctic climate, the tortuous lay of the land, and the varied compositions of soil, rock, or permafrost (permanently frozen ground). A little more than half of the pipeline is elevated above the ground. The remainder is buried anywhere from 3 to 12 feet, depending largely upon the type of terrain and the properties of the soil. One of the largest in the world, the pipeline cost approximately $8 billion and is by far the biggest and most expensive construction project ever undertaken by private industry. In fact, no single business could raise that much money, so eight major oil companies formed a consortium in order to share the costs. Each company controls oil rights to a particular share of land in the oil fields and paid into the pipeline-construction fund according to the size of its holdings. Today, despite enormous problems of climate, supply shortages, equipment breakdowns, labor disagreements, treacherous terrain, a certain amount of mismanagement, and even theft, the Alaska pipeline has been completed and is operating.Which phrase in the first paragraph mean Supported by?
