Science

maybe from university but at secondary school and below, only in the three sciences (physics, biology and chemistry) other wise it's just common sense, if you can't multiply you will struggle so it's strongly recommended that you can

1)Complete the international space station

2)Develop , build and fly a new crew exploration vehicle, by 2014.

3)Develop a program to return humans to the moon, establish a lunar base and pursue subsequent exploration of mars and other destinations .

Yes, smoke from forest fires can contain harmful pollutants like carbon monoxide, particulate matter, and volatile organic compounds that can have adverse effects on people's health, especially those with respiratory conditions. Prolonged exposure to the smoke can lead to symptoms such as coughing, shortness of breath, and irritation of the eyes, nose, and throat. It is important to take precautions such as staying indoors and using air purifiers during periods of heavy smoke.

In December, the Southern Hemisphere gets slanting rays of the sun, as it is summer in that part of the world during this time. The Tropic of Capricorn receives direct sunlight, causing the rays to hit the Earth at a more oblique angle, resulting in slanting rays.

A wheelbarrow is considered a class 2 lever, where the load (the items being carried) is between the effort (the force applied to lift the handles) and the fulcrum (the wheel).

The concept of hypochondria has been documented since ancient times, with references found in texts from ancient civilizations such as Egypt and Greece. However, it was formally recognized and defined in modern medicine during the 19th century as a mental health disorder characterized by excessive worry about one's health without a basis in medical reality.

The length of a rotation can vary depending on the context, such as in astronomy where it can range from a few hours to several days for objects like planets. In a medical or professional setting, a rotation typically lasts for a predetermined period, in the case of medical residencies for example, they can range from a few weeks to a few months per rotation.

For all practical purposes, it is inexhaustible, but in absolute fact, it is not. The fact that the sun has been the Energizer Bunny for about 4.5 billion years, and will be for about 4 billion more is mostly because of it's size - it's impossible to grasp just how much hydrogen comprises the sun, and it isn't even considered a very big star, as stars go. But one day, it will use up the last of it's hydrogen, and collapse inward on itself becoming a white dwarf.

The trick with testing animals for their hearing is that they do not necessarily want to tell you what they do or do not hear, so you have to create some reason for them to react to faint sounds. You could, for example, build a large series of buttons, designed so that you can have any one of them emit a sound, of any desired loudness, and if that button is pressed when it makes a sound, the animal is rewarded with food. (Not all animals can press buttons, but equivalent mechanisms can be devised that would meet the requirements of other animals.) Then, when the animal is trained to respond to sound, you can find out how faint the sound can be while still getting the animal to respond. Then, if you test every species of animal, you can compare results and find out which animal has the best hearing.

The Arecibo message was a simple binary-encoded message sent in 1974 from the Arecibo Observatory in Puerto Rico towards a distant cluster of stars. It contained information about Earth's location in the galaxy, our binary numbers, human DNA, and a representation of a human figure. Its purpose was to showcase our technological capability and potentially initiate communication with extraterrestrial civilizations.

In space, astronauts do not hear sound as we do on Earth because there is no air to transmit sound waves. However, they can communicate with each other and with Mission Control using radios and headphones inside their helmets. They may also hear vibrations transmitted through their spacecraft.

Rockets are things that you have to be smart to build and/or fly. And as we all know, science is very smart, so it would only make sense, that they put together two smart things, and called it rocket science. This in turn proves that scientists would need to work on a rocket which means that they would be working in the scientology department of rocketships.

Postscript was developed by Adobe Systems and first released in 1985.

The three are making a "to-do" list to organize their tasks for the day. Each person is contributing items they need to complete to ensure they don't forget anything important.

Zeppelins are typically made of an aluminum frame covered in fabric, with internal gas cells that contain the lifting gas (typically helium). The outer covering of the zeppelin is usually made of a lightweight synthetic fabric to reduce weight and increase buoyancy.

You would go to an observatory or a space research center equipped with powerful telescopes and other instruments specifically designed for observing objects in space. These facilities are staffed by experts who can help guide your observations and provide insights into what you are seeing.

New resources found in outer space include water ice on the Moon, asteroids rich in precious metals like platinum, and potential sources of helium-3 for fusion energy. These resources have the potential to support future space exploration and fuel economic growth in space industries.

Yes, beans can grow under different colored lights, but the type of light can affect the growth and development of the plant. Plants typically respond best to blue and red light wavelengths for photosynthesis and growth, while green light is less effective. It's important to provide the right balance of light colors for optimal bean growth.

The force of gravity pulls matter inward, while the force of thermal pressure (from the heat of the gas) pushes matter outward. When these two forces are balanced, a nebula can remain stable without collapsing or expanding.

An obvious example would be the computer/laptop/whatever you are typing into! Mass is defined as an object's resistance to changes in motion in its most simple form in Physics, or, perhaps, you have have learned it as the amount of matter in something. Well, going by the former definition, the computer you are typing into has mass because it resists changes in position, and it also takes up space (obviously).

Depends on the size, speed, and composition of the asteroid. It could burn up in our atmosphere. It could hit the ground harmlessly as a small grain of sand. It could explode in the lower atmosphere and level thousands of square miles of forest. It could hit the ocean and cause a massive tsunami. It could leave an impact crater the size of Texas and throw enough debris into the atmosphere to start a very long "nuclear winter". It could split the earth in two.

Sunspots are structures commonly found in the photosphere of the Sun. These dark regions are caused by magnetic activity and are cooler than the surrounding areas, hence appearing dark against the brighter photosphere. Sunspots often occur in pairs with opposite magnetic polarities.

A Mylar balloon is a type of balloon made from a shiny, metallic polyester film called Mylar. These balloons are known for their durability and long-lasting qualities compared to traditional latex balloons. Mylar balloons are often used for special occasions like birthdays and celebrations.

Solar blackouts can occur due to a variety of reasons such as solar flares or coronal mass ejections from the sun that can disrupt electromagnetic fields and interfere with satellite communication or power grids on Earth. These natural phenomena can lead to temporary disruptions in electronic systems and can affect radio communication or power distribution.

Dr. Jeffrey W. Dellimore's field of study was in psychology, focusing on cognitive psychology and human behavior. He conducted research on memory processes, decision-making, and cognitive development.
