Science
The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.
203,801 Questions
What causes the earth to move around the sun?
The Earth moves around the Sun due to gravitational attraction between the two. The Sun's gravity pulls the Earth towards it, causing the Earth to orbit around the Sun. This gravitational force keeps the Earth in its elliptical path around the Sun.
What is the center of the solar system called?
The Sun is at the center of the Solar System.
the SUN is the centre of our solar system.
What type of scale pattern is found in dog hair?
Dog hair typically exhibits a medullary index scale pattern, which means that the scales are small and spaced close together along the shaft. This scale pattern helps to protect the hair shaft and provides insulation for the dog's fur.
What are some advantages of studying heredity in plants and simple organisms?
Studying heredity in plants and simple organisms allows for easier manipulation of genetic traits due to simpler genomes. These organisms often have shorter generation times, facilitating faster analysis and experimentation. Additionally, findings from these studies can offer insights into genetic principles that can be applied to more complex organisms, including humans.
On what properties does the force of gravity between two objects depend?
The strength of a gravitational field at any given point is proportional to the planetary body's mass and inversely proportional to the square of the distance from the center of the body.
What animals live in a temperature woodland and shrubland?
Animals that live in a temperate woodland and shrubland biome include deer, foxes, rabbits, squirrels, birds like owls and woodpeckers, and various insects. These animals have adapted to the seasonal changes and diverse plant life found in these environments.
What is a force between all masses?
The force between all masses is called gravitational force. It is an attractive force that exists between any two objects with mass, and it is responsible for phenomena such as the orbits of planets around the sun and the falling of objects near Earth's surface.
The lifespan of a candle can vary depending on factors like its size, composition, and how it is burned. On average, a standard-sized candle can last anywhere from 20 to 40 hours. Factors such as draftiness, wick length, and proper extinguishing can also affect how long a candle lasts.
How does the concentration of vinegar affect the germination of radish seeds?
A higher concentration of vinegar can inhibit germination of radish seeds due to its acidic nature, which can disrupt the seeds' ability to absorb water and nutrients. Lower concentrations of vinegar may have minimal impact on germination.
What substance cannot be photographed because it reflects too much light?
A substance that cannot be easily photographed because it reflects too much light is glass. The transparency and reflective nature of glass can cause issues with capturing a clear image without proper lighting techniques.
How much does it cost to make a space suit?
It depends on where the space suit is being worn to. The space suits that have been made in the past have taken millions of dollars to build. Even closer to an exact answer, probably about 3 million.
What is the solar system made of?
Mercury's mass = 3.30 x 1023kg or 0.055 x Earths
Venus' mass = 4.87 x 1024kg or 0.815 x Earths
Earth's mass = 5.97 x 1024kg or 1 x Earths
Mars' mass = 6.42 x 1023kg or 0.1075 x Earths
Jupiter's mass = 1.90 x 1027kg or 317.8 x Earths
Saturn's mass = 5.69 x 1026kg or 95.152 x Earths
Uranus' mass = 8.68 x 1025kg or 14.536 x Earths
Neptune's mass = 1.02 x 1026kg or 17.147 x Earths
Whats the temperature on Mars?
The average temperature on Mars is about -80 degrees Fahrenheit (-62 degrees Celsius), but it can vary greatly depending on the location and time of day. Temperatures can range from as low as -195 degrees Fahrenheit (-125 degrees Celsius) to as high as 70 degrees Fahrenheit (20 degrees Celsius) near the equator during the day.
How do you become star greenhand?
I was StarGreenhand this year. you need to excell above the others in your grade in SAE(supervised agricultural experiance), classroom and FFA. SAE, i raise livestock i show cattle and have several acres to farm. Classroom A all quarters, and lastly, be very active in your chapters FFA. It's up to you now! Good Luck!! : ) Christy
Scientist can use light to move matter. For example, with directed beams of light, scientist can levitate, trap and grip small materials. The matter has to be surround by light entirely for this to work.
Why the sun will increase in size as it begins to burn off its fuel?
As the denser material which results from the reactions in the sun move closer to the center under gravitational pull the center mass is distanced from the outer reaches of the sun's surface. Less gravitational effect on the outer surface allows the surface to move further away. The overall gravitational effect will lessen over time as material is ejected away from the sun through the solar wind and other processes as well.
Why is daily exercise essential in space?
Well im looking for the same answer but i might think that its because your weight is much lighter and its harder to exersize in space because you don't 'feel the burn' when your up there because for every = action there is a reactions but how do you exersize with no gravity? it would be hard to burn calories and even if your tried to exersize you would not be able to burn that many calories because you cant really move for yourself.
What is the scientific definition for the word succession?
Succession is the slow, regular sequence of changes in the development of communities of plants and animals. The principle of faunal and floral succession states that because animals and plants evolve into new species, sedimentary rocks of different ages will contain fossils of different species.
> Ø Science is systematic organized knowledge obtained by method based upon empirical observation. Ø According to Webster's New Collegiate Dictionary, the definition of science is "knowledge attained through study or practice," or "knowledge covering general truths of the operation of general laws, esp. as obtained and tested through scientific method [and] concerned with the physical world." Ø Science refers to a system of acquiring knowledge. This system uses observation and experimentation to describe and explain natural phenomena. The term science also refers to the organized body of knowledge people have gained using that system. Less formally, the word science often describes any systematic field of study or the knowledge gained from it. Ø Science as defined above is sometimes called pure science to differentiate it from applied science, which is the application of research to human needs. Fields of science are commonly classified along two major lines:
- Natural sciences, the study of the natural world, and
- Social sciences, the systematic study of human behavior and society. Ø A science is a set of rules for evidence gathering and testing claims against fact and logic, rules which are publicly usable, neutrally applied to all participants, and which can reasonably be said to lead to the truth of that particular area.
In science, how much an item weighs is defined as the force of gravity on that item. The SI unit for weight is the newton.
Solar energy is obtained through the use of solar panels which capture sunlight and convert it into electricity. These panels contain photovoltaic cells that absorb photons from the sun and generate a flow of electrons, creating an electrical current. This electrical current can then be used to power homes, buildings, and other devices.
Solar quantities refer to measurements or characteristics associated with solar energy, such as solar radiation, solar insolation, solar irradiance, or solar intensity. These quantities are used to evaluate the amount of sunlight available for generating electricity through solar panels or for other solar applications.
Can a space shuttle go17500 in the atmosphere?
No, a space shuttle travels at a speed of about 17,500 miles per hour in space, not in Earth's atmosphere. When entering the atmosphere, it slows down significantly to prevent overheating due to air resistance.
What objects are non sustainable?
Objects made from materials that are not easily renewable or biodegradable, such as single-use plastics, Styrofoam, and electronic waste, are considered non-sustainable. These objects contribute to environmental pollution and resource depletion.
Orion's Belt is a prominent asterism in the constellation Orion, comprised of three bright stars located in a straight line. These stars, known as Alnitak, Alnilam, and Mintaka, are easily visible in the night sky and are used as a navigational reference point for locating other stars and constellations.
