Answer:

free body diagram can be used to help work out the net force acting on an object. True or, false?

Columbian exchange. Tell a story in chronological order of the changes that the community undergoes as it and the communities around it make contact with Europeans over a span of roughly 50 to 100 years.

This section is worth 20 points. See the scoring rubric for more details on how you

will be graded

Use the evidence you gathered to tell the story of a hypothetical indigenous

community in the Americas and its experience involving the Columbian Exchange.

Come up with a community whose circumstances are typical of many in Central

America, the West Indies, or another part of the Americas that had direct contact with

Europeans. Tell the story in chronological order, but feel free to skip whole years or

decades so that you can cover each of the important topics related to the activity: the

availability of goods, the effects of disease, and the impact of European culture

(language and religion, for example), at the very least.

Think of your story as more of a summary than a work of fiction; you must cover a

large span of time in few words. Base the details of the story on factual evidence and

cite your sources, but keep in mind that the text should be written as a story, not as

an essay with a conventional introduction, body, and conclusion. Aim for about 700

to 1,200 words.

!!Help!!
Ira Lisetskai [31]

Answer:

s = 37.81 m

Explanation:

Given that,

Mass of an apple, m = 1.5 kg

The apple falls for 2.75s before striking the ground.

We need to find how far the apple dropped before hitting the ground. It means we need to find the distance covered. Using the second equation of motion to find it :

s=ut+\dfrac{1}{2}gt^2

u is initial velocity, u = 0 (at rest)

s=\dfrac{1}{2}gt^2\\\\s=\dfrac{1}{2}\times 10\times (2.75)^2\\\\=37.81\ m

So, Apple dropped 37.81 m before hitting the ground.

A comet speeds up as it approaches the Sun. Which statement about its kinetic energy is correct?(1 point)
krok68 [10]

A comet speeds up as it approaches the Sun. Which statement about its kinetic energy is correct option is - (1) The comet has no kinetic energy because it is in outer space.

  • Large ice and dust-based bodies known as comets circle the Sun. These ancient objects, which are best known for their long, streaming tails, are relics from the solar system's birth 4.6 billion years ago. The majority of comets are located outside of our solar system. Some are found in the Kuiper Belt, a vast disc that extends past Neptune's orbit. These are known as short-period comets. They orbit the Sun in lesser than 200 years.
  • The Outermost Layer, the solar system's sphere-shaped outer edge, which is nearly 50 times further from the Sun than the Kuiper Belt, is home to additional comets. Because of how much longer it takes them to orbit the Sun, these are known as long-period comets. The comet with the longest known orbit completes one orbit in excess of 250,000 years.

A vibrating object produces periodic waves with a wavelength of 53 cm and a frequency of 15 Hz. How fast do these waves move awa
DerKrebs [107]

Answer:

v = 7.95 m/s

Explanation:

Given that,

Wavelength of a wave, \lambda=53\ cm=0.53\ m

Frequency of a wave, f = 15 Hz

We need to find the speed of the wave. The speed of a wave is given by :

v=f\lambda\\\\v=15\ Hz\times 0.53\ m\\\\v=7.95\ m/s

So, the wave move with a speed of 7.95 m/s.
