Adam, who is 5'6" tall, notices his shadow on the sidewalk. If the angle of elevation from the tip of the shadow to the sun is 60°, what is the distance from the tip of the shadow to the top of his head? (round to 2 decimal places)

Answers

Final answer:

Using trigonometry and the tan function, we calculate that the distance from the tip of Adam's shadow to the top of his head is approximately 76.22 inches.

Explanation:

To determine the distance from the tip of Adam's shadow to the top of his head, we use trigonometry involving right-angled triangles. Specifically, we can utilize the tan function which is defined as the opposite side over the adjacent side in a right-angled triangle. Given that the angle of elevation is 60° and Adam's height is 5'6" (which is 66 inches), we can set up our equation based on the tan function.

The tan of 60° equals the height of Adam (opposite side) divided by the length of the shadow (adjacent side). As tan(60°) = √3, and the height of Adam is 66 inches, we get √3 = 66 / length of shadow. Solving for the length of shadow, we find it equals 66 / √3 inches. To find the distance from the tip of the shadow to the top of Adam's head, which is the hypotenuse in this scenario, we use the Pythagorean theorem or recognize the special 30-60-90 triangle ratio.

In a 30-60-90 triangle, the hypotenuse is twice the length of the shorter side (which here is the shadow's length). After calculating, we find the length of the shadow to be approximately 38.11 inches, making the hypotenuse (distance from the tip of the shadow to Adam's head) approximately 2 x 38.11 = 76.22 inches.

The distance from the tip of Adam's shadow to the top of his head is approximately 3.18 feet.

To solve this problem, we can use trigonometry and the concept of similar triangles.

First, let's define the variables:

- Let (h) be the height of Adam (from the ground to the top of his head).

- Let [tex]\( d \)[/tex]  be the distance from the tip of Adam's shadow to the top of his head.

- Let[tex]\( \theta \)[/tex] be the angle of elevation from the tip of the shadow to the sun (given as [tex]\( 60^\circ \)[/tex]).

Now, we can set up a proportion using the tangent function:

[tex]\[ \tan(\theta) = \frac{h}{d} \][/tex]

Given that [tex]\( \theta = 60^\circ \)[/tex], we have:

[tex]\[ \tan(60^\circ) = \frac{h}{d} \][/tex]

[tex]\[ \sqrt{3} = \frac{h}{d} \][/tex]

Now, we need to find the length of Adam's shadow. Since Adam is 5'6" tall, and his shadow is formed by the sun's rays, which are nearly parallel, the length of his shadow is directly proportional to his height. Thus, if Adam is 5'6" tall, his shadow will also be 5'6" long.

Using the proportion [tex]\( \frac{h}{d} = \sqrt{3} \)[/tex], and substituting [tex]\( h = 5.5 \)[/tex]feet (since 5'6" is 5.5 feet), we can solve for ( d ):

[tex]\[ d = \frac{h}{\sqrt{3}} = \frac{5.5}{\sqrt{3}} \approx 3.18 \text{ feet} \][/tex]

So, the distance from the tip of Adam's shadow to the top of his head is approximately 3.18 feet.

The complete ques is :

Adam, who is 5'6" tall, notices his shadow on the sidewalk. If the angle of elevation from the tip of the shadow to the sun is 60°, what is the distance from the tip of the shadow to the top of his head? (round to 2 decimal places)

Answers

Answer:

From the point of view of historical geology, sedimentary rocks (option B) have characteristics that allow being the most useful to discover the events that occurred in the past.

Explanation:

Sedimentary rocks are the product of the lithification of the sediments of rocks originated by the weathering (meteorization) process, transported in the form of particles by environmental agents such as wind, rain, sea swell, among others.

The sediments that are deposited on the surface of the planet, over many years, go through a hardening process that turns them into rocks with heterogeneous material.  The characteristics that make sedimentary rocks the ideal material for historical geology studies are:

The formation process, where particles from past eras are found.

Its structure more or less accurately indicates the environmental conditions of the time they originated.

They contain information about their formation mechanism.

Fossils, also evidence of past times, are found in sedimentary rocks.

In order for geologists to reconstruct events and characteristics of the past, sedimentary rocks provide valuable information that contributes to this work.

The Andes mountain range of South America was formed at a ____.
a.
convergent boundary
c.
hot spot
b.
divergent boundary
d.
transform boundary

Answers

The Andes mountain range of South America was formed at a A. convergent boundary.
Convergent boundary gives rise to various types of mountains once two tectonic plates collide and create mountainous formations.

The correct answer is - a. convergent boundary.

The formation of the longest and highest mountain range in South America can be attributed to the collision of the Nazca tectonic plate and the South American tectonic plate. This two tectonic plates form a convergent boundary. That basically means that they are pushing against each other, and because of the incredible force and pressure, the land starts to lift up gradually in the surrounding are, thus forming a mountain range over time. In this case the result has been the formation of the Andes, that are stretching in a linear manner, in a roughly north-south direction, from the northern part of the continent to its southern part, in close proximity of the Pacific coastline.

A measure of the amount of light given off by a star is its _____.

Answers

A measure of the amount of light given off by a star is its luminosity. 
It is the intrinsic brightness of a celestial object (as distinct from its apparent brightness diminished by distance).

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

Final answer:

A measure of the amount of light given off by a star is its luminosity and apparent brightness. Luminosity refers to the total energy output of a star, whereas apparent brightness is how much of that energy reaches an observer on Earth, influenced by both the star's luminosity and its distance from Earth.

Explanation:

A measure of the amount of light given off by a star is its luminosity and apparent brightness. Luminosity is defined as the total amount of energy a star emits per unit time, usually measured in watts. It provides a scale to compare the energy output among different stars, with some stars having luminosities many times that of our sun. On the other hand, apparent brightness refers to the energy from the star that reaches an observer or a square meter of surface area on Earth each second, measured in watts per square meter (W/m²). This is influenced not only by a star's luminosity but also by its distance from Earth. Thus, when observing stars, astronomers distinguish between these two to understand both the star's true power output and how much of that power actually reaches us.

The determination of a star's apparent brightness, along with measurements of its distance from Earth, allows astronomers to calculate its luminosity. This calculation is vital for understanding not just how bright a star appears to us but its overall energy output in the vastness of space. The concept of magnitudes is often used to express apparent brightness, relating to how human vision interprets light intensity.

Final answer:

Panama is indeed located between South America and North America, connected by the Isthmus of Panama and bordered by the Caribbean Sea and the Pacific Ocean.

Explanation:

The statement "Panama is located between South America and North America" is true. The Isthmus of Panama is the narrow strip of land connecting the two continents, with Costa Rica to its northwest and Colombia to its southeast. Panama serves as a land bridge between North and South America and is bordered by the Caribbean Sea to the north and the Pacific Ocean to the south. This strategic location played a significant role in history, particularly during the colonial period when the region was controlled by colonial Colombia, and later in the construction of the Panama Canal, which significantly shortened maritime travel times by allowing ships to pass between the Atlantic and Pacific Oceans without circumnavigating South America.

Why are there so many earthquakes in South America?

Answers

The western part of South America is a region that is geologically very active. This is due to the boundaries between the South American tectonic plate with the Nazca tectonic plate, and also with the Pacific tectonic plate. Since both, the Nazca and the Pacific plates are oceanic plates, they are heavier, and they subduct below the lighter plate of South America, thus enabling the pressure and temperature from the mantle to come out towards the surface on this boundary lines. This creates lots of earthquakes, as well as volcanic activity.

Due to its placement along tectonic plate boundaries as well as the presence of subduction zones, South America is prone to earthquakes.

The following are the causes of South America's high seismic activity:

1. Tectonic Plate Boundaries: South America's continent is positioned at the intersection of many tectonic plates. Along the Peru-Chile Trench, the Nazca Plate is subducting beneath the South American Plate, causing frequent and strong earthquakes in the region.

2. Subduction Zones: Subduction is the movement of one tectonic plate beneath another. The Andean subduction zone is formed in South America by the subduction of the Nazca Plate beneath the South American Plate. This zone runs over South America's western coast, creating strong seismic activity.

Despite the fact that South America is prone to earthquakes, the frequency and intensity of seismic activity vary across the continent.

How much does the atlantic ocean widen per year due to divergent boundaries

Answers

Answer:

About 2.5 centimeter per year

Explanation:

At the divergent boundaries the earth lithospheric plates moves away from each other . This occurrence might be in the continental plate/crust or oceanic plates/crust. The divergent boundary can be noticed in the middle of an ocean . This is the type of boundary occurring in the Atlantic ocean. The diverging rate at the Atlantic ocean is very slow at about 2.5 cm per year. The plates are moving away from each other thereby causing the up-welling of magma to create a new oceanic crust.  The divergent boundary on the ocean floor like Atlantic ocean is usually found on the crest of the mid oceanic ridges. The boundary is also marked by shallow earthquakes and faults.
