Why do aluminium and titanium not normally react?

Aluminum and titanium have a protective oxide layer on their surface that prevents them from further reacting with oxygen in the air. This oxide layer acts as a barrier and prevents the metals from undergoing further oxidation reactions.

When one object applies a force to a second we call this force the?

When one object applies a force to a second object, we call this force the action force.

Would what Sugar is made of the study by physical scientist?

Sugar is made of carbon, hydrogen, and oxygen atoms. Physical scientists study the properties and behavior of matter and energy, so they may investigate the physical and chemical properties of sugar molecules and how they interact with other substances. This can involve examining sugar's structure, its solubility, melting point, and other physical characteristics.

Why do scientists use in diagrams of electrical circuits?

Scientists use symbols for diagrams of electrical circuits for a simple reason; to save space. The actuall names of the components would take up immense space on the diagram.

Why have scientist models for the structure of Atoms?

To make them easier to understand. To make it possible to visualize the atoms and understand what they're actually doing. It helps to understand how they interact with each other and how they interact with other things.

What scientist described the laws of inertia?

Sir Isaac Newton described the laws of inertia as part of his work on classical mechanics in his famous publication, "Philosophiæ Naturalis Principia Mathematica" in 1687.

What 3 elements where named after famous scientists?

  1. Curium (Cm) was named after Marie and Pierre Curie, the pioneers of radioactivity.
  2. Einsteinium (Es) was named after Albert Einstein, the renowned physicist known for his theory of relativity.
  3. Fermium (Fm) was named after Enrico Fermi, the Italian physicist who conducted pioneering research in nuclear reactions and particle physics.

What technological device is most used by scientists?

Computers are the most used technological device by scientists. They are essential for data analysis, simulations, modeling, research documentation, and communication within the scientific community.

Who is the best medical scientist in the world?

Louis Pasteur can be considered one of the best medical scientists in the world since he came up with the pasteurizing process for milk (we don't realize how germ-ridden unpasteurized milk is since it is so uncommon in the US), vaccines for many diseases (anthrax, rabies), and did a bunch of other stuff.

Another may be Robert Koch, who with Pasteur, helped forward the germ theory.

Really, there isn't any 'best' medical scientist since it all depends on how you qualify what is 'best,' which scientists are always trying to do!

What is the method scientists could use to find weather nanoparticles can get into the blood and cause heath problems?

Scientists could conduct in vitro and animal studies to investigate the interaction between nanoparticles and blood cells. They can also perform human clinical trials to determine if nanoparticles can enter the bloodstream and affect health. Additionally, advanced imaging techniques such as electron microscopy can be utilized to visualize nanoparticle-blood cell interactions.

Why did some scientists disagree with the phlogiston theory?

Some scientists disagreed with the phlogiston theory because it could not explain all the observations, such as the weight changes in substances during combustion. Additionally, the discovery of oxygen and its role in combustion provided a more accurate explanation for the phenomena previously attributed to phlogiston.

What force of 2.0 kg mass and acceleration of 5.0 MS's on a level surface what is the force applied to the mass?

The force applied to the mass can be calculated using Newton's second law, which states that force equals mass times acceleration. Thus, the force can be calculated as force = mass * acceleration = 2.0 kg * 5.0 m/s^2 = 10 N.

What type of scientist studies oxygen?

Chemists study oxygen, its chemical properties, and reactions involving oxygen

Biologists study oxygen - it's availability and how it is used and produced by organisms

Environmental scientists study how oxygen levels affect the environment and how the environment affects oxygen levels - including oxygen levels in both the atmosphere and dissolved in water.

Why A scientist helps a colleague do a better experiment by?

providing guidance and expertise in research methods or techniques, suggesting improvements in the experimental design, offering constructive feedback on data analysis, or discussing potential interpretations of the results. Collaboration and peer feedback are essential in scientific research to ensure the validity and reliability of experimental outcomes.

Who was the first scientist to view diffusion?

The first scientist to observe diffusion was botanist Robert Brown in 1827, who noticed the random motion of pollen particles in water. This phenomenon of particles moving from areas of high concentration to low concentration is now known as Brownian motion.

How does a propeller move a object?

A propeller moves an object by generating thrust through the rotation of its blades. As the blades spin, they create a pressure difference between the front and back of the propeller, pushing air or water in one direction and creating a force that propels the object forward.

In 1800 Humphrey Davy invented the first electric light bulb. What scientific discovery made Davy's invention possible?

Humphry Davy's invention of the first electric light bulb in 1800 was made possible by Alessandro Volta's invention of the electric battery in 1800. The electric battery provided a stable and continuous source of electric current needed to power the light bulb.

Why was atomism largely ignored during the Middle Ages?

Atomism was largely ignored during the Middle Ages because it contradicted religious beliefs. The idea that matter was made up of indivisible particles went against the prevailing view of the time, which was heavily influenced by Aristotelian philosophy. Additionally, atomism lacked experimental evidence to support it, making it less appealing to scholars who prioritized observation and logic.

What information did Mendeleyev write about each elements on his cards?

Mendeleev's cards contained information about the atomic mass, chemical properties, and behavior of each element. He also organized the cards in a way that allowed him to determine patterns and relationships between different elements. This led to the development of the periodic table of elements.

What are the advantages of scientists working together?

Scientists working together can leverage each other's expertise and resources, leading to more innovative and comprehensive research outcomes. Collaboration allows for diverse perspectives and ideas to be integrated, leading to better problem-solving and faster progress in scientific discoveries. Additionally, working in teams can help in sharing the workload and tackling complex research questions that require interdisciplinary approaches.

How did Alexander Fleming's invention work?

Alexander Fleming discovered penicillin, the world's first antibiotic, by observing that a mold called Penicillium notatum inhibited the growth of bacteria. The penicillin produced by the mold effectively killed or slowed the growth of many types of harmful bacteria, making it a groundbreaking treatment for bacterial infections. Fleming's discovery revolutionized medicine and has saved countless lives since its development.

How did Antoine Lavoisier develop the modern definition a chemical element?

Antoine Lavoisier developed the modern definition of a chemical element by recognizing that elements cannot be broken down into simpler substances through chemical means. He conducted numerous experiments to determine the conservation of mass during chemical reactions, leading to the concept of the conservation of matter and the identification of elements as the basic building blocks of matter.

Is steven hawking a Muslim?

No, Stephen Hawking was not a Muslim. He identified as an atheist and did not adhere to any organized religion.
