Answers

Answer 1

Answer:

You can clearly see the spring that makes the pointer rise or fall as the pressure changes. ... A spring is cunningly attached to the box and, as the box moves in and out in response to the changes in air pressure, the spring expands or contracts and moves the pointer on the dial.......i'm going to say C

What is a barometer?

An device known as a barometer is utilized to measure the air speed in a specific environment. Weather trends in the short term can be predicted by atmospheric tendency. To identify surface dips, precipitators, and frontal borders, local meteorological forecasting use a variety of air pressure data.

An aneroid barometer has a little flexible metal box within. That's because the air in this cylinder has been forced out, even little variations in the air density outside cause the iron to expand and contracts. Mechanical levers within are moved by the elastic deformation, which moves a needle.

Therefore, option C is the correct option.

What allowed homosapiens to migrate further than earlier people?​

Answers

Answer:

Scientists studying land masses and climate know that the Pleistocene Ice Age created a land bridge that connected Asia and North America (Alaska) over 13,000 years ago. A widely accepted migration theory is that people crossed this land bridge and eventually migrated into North and South America.

How were our ancestors able to achieve this feat, and why did they make the decision to leave their homes? The development of language around 50,000 years ago allowed people to make plans, solve problems, and organize effectively. We can’t be sure of the exact reasons humans first migrated off of the African continent, but it was likely correlated with a depletion of resources (like food) in their regions and competition for those resources. Once humans were able to communicate these concerns and make plans, they could assess together whether the pressures in their current home outweighed the risk of leaving to find a new one.

Answer:

Hunter gatherers are groups of people who move from place to place in search of food and other needed natural resources. They rely heavily on the environment for everything they need to survive, including food, shelter, clothing, tools, and even medicines. For instance, these groups will use every part of a hunted animal to survive: meat is used for food, skin for clothing and shelter, and other remains for tools and weapons. These groups will also gather any nuts, berries, and fruits they can find. The Paleo-Indians were early hunter-gatherers in North America.

List at least two ways Booker T. Washington demonstrated perseverance in his life.

Answers

Answer:

"Booker" (the only name he had as a slave) decided early on that the key to life was a good education.

Booker was nine when slavery ended. His stepfather insisted that he work in a salt mine to help support the family. But Booker wanted to go to school, so he figured out a way to do both. He worked at the mine from 4 to 9 am in the morning, then went to school, and returned to the mine to work from 2 in the afternoon to 9 at night. A 12 hour workday PLUS school!

When he was 12, he heard about Hampton Institute, where he could continue his education. Even though it was 500 miles away, he talked his mother into letting him go. Then, he ran out of money halfway there. So, he walked over 200 miles to get there.
