Scientists concluded that cathode rays were negatively charged particles that carried momentum. They inferred this from the movement of the paddle wheel, which indicated that the cathode rays possessed kinetic energy and could transfer their momentum to the wheel as they collided with it.
What scientist was the unit of Ohms named after?
The unit of Ohms was named after the German physicist Georg Simon Ohm, known for Ohm's Law which relates the voltage across a conductor to the current flowing through it.
Which scientist first postulated the existence of ions?
Michael Faraday is credited with first postulating the existence of ions in 1834. He observed that chemical compounds decompose into electrically charged particles when dissolved in water and demonstrated that electric current could flow through a solution of ions.
Scientists do not record their results after completing experiments?
Recording results after completing experiments is a crucial step in the scientific process to document findings, draw conclusions, and communicate results to the scientific community. This practice ensures transparency, reproducibility, and the advancement of knowledge in the field.
What 3 problems did the Wright Brothers solve that had baffled scientists?
Who is the dear student of Humphry Davy?
Michael Faraday was a dear student of Humphry Davy. Faraday went on to make significant contributions to the fields of electromagnetism and electrochemistry.
What nickname was given to rutherford's model of the atom?
The model atom Ernest Rutherford made is simply called the Rutherford Model. The experiment he conducted during his research is referred to as the Gold Foil Experiment. Rutherford is known as the father of nuclear physics.
What is the primary reason scientist repeat the measurements they take during experiments?
Scientists repeat measurements to ensure the reliability and reproducibility of their results. By conducting multiple measurements, they can identify any errors or inconsistencies in their data and make more accurate conclusions. It also helps to confirm the validity of their findings.
Why did Nikola Tesla invent a plasma ball?
This is the first time someone mentions the plasma ball in the few years I been in wikianswers. I like this question because with the plasma ball we could see how Tesla conducted his experiments. Tesla invented the plasma lamp for his experiments with high frequency currents of electricity in a vacuum glass tube, scientifically called an "evacuated tube" The Plasma Ball or lamp was actually first named by Tesla as "an inert gas discharge tube" for a better description.
He wanted better light bulbs and he created those as well.
What happen between thomas Edison and nikola telsla?
Thomas Edison was supplying electricity in New York with direct current. Those systems were bad causing fires and other hazards like electrocution in homes. When Nikola Tesla arrived to New York, he began working for Thomas Edison.
The first task assigned to him was fixing his direct current motor a a prize of $50,000. When he finished that, Edison didn't kept his world so Tesla walked out the place never to return.
Later in life, his alternate current beat Edison's direct current system and it was chosen for the 1893 fair. Edison in envy put in court that Tesla couldn't use his bulbs. So the Westinghouse co. made the bulbs for the fair.
What kind of scientist studies metal?
A metallurgist is a scientist who specializes in the study of metals, their properties, and how they can be used in various applications. They may work to develop new metal alloys, improve metal production processes, or study the behavior of metals under different conditions.
Where did Nikola Tesla invent the coil?
A Tesla coil is a type of resonant transformer circuit invented by Nikola Tesla around 1891. It is used to produce high voltage which Tesla used to test a way to conduct wireless electricity. Something about Tesla was that his inventions were not an accident like most inventions. He visioned the inventions in his head and then make them work.
The Tesla coil experiments were done or conducted in the Colorado Springs laboratory. We could think that the first Tesla Coil was built there but the idea could be in his head way back from New York when he was working with George Wentishouse.
What is something scientists use to help explain something that is very small or very large?
Scientists use the concept of scale to help explain things that are very small or very large. They may use measurements in nanometers or micrometers for tiny objects, and in astronomical units or light-years for massive objects to provide a sense of scale. Additionally, they often employ models and visualizations to illustrate these concepts in a more understandable way.
How does Doppler radar help scientists know what is happening in a thunderstorm?
Doppler radar measures the velocity of precipitation particles in a thunderstorm, allowing scientists to track wind speeds, precipitation intensity, and storm movement. This information helps them to understand storm dynamics, predict severe weather, and issue warnings to protect lives and property.
How do you contribute to the country as a chemist?
As a chemist, I contribute to the country by conducting research that can lead to the development of new medicines, materials, and technologies. I also provide expertise in areas like environmental protection, food safety, and forensic analysis that can benefit society as a whole. Additionally, I may train future scientists and engineers, helping to ensure a workforce prepared to handle future challenges.
Confirmation bias and attachment to prevailing theories can lead otherwise good scientists to ignore the more scientifically valid rapid decay theory. They may feel more comfortable sticking to established beliefs and may be resistant to considering new ideas that challenge current understanding.
Why did Nikola Tesla invent the induction motor?
Nikola Tesla invented the induction motor with rotating magnetic field that made unit drives for machines feasible and made AC power transmission an economic necessity. With this, Tesla set the basis for machinery and households to be powered with ac electriticity.
What is the name of the scientist that studies motion force and energy?
Newton is the first and the most famous is Enstein
Amedeo Avogadro was an Italian scientist who is known for his contributions to molecular theory. He introduced Avogadro's law, which states that equal volumes of gases at the same temperature and pressure contain the same number of molecules. Avogadro's constant, a fundamental physical constant used to relate the number of particles to the amount of substance in a sample, is named in his honor.
Which scientist developed the quantum mechanical model of the atoms?
The quantum mechanical model of the atom was developed by Erwin Schrödinger in 1926. His work built upon the earlier discoveries of other scientists, such as Max Planck and Albert Einstein, in the field of quantum mechanics.
Who created the term horsepower?
The term "horsepower" was created by Scottish engineer James Watt in the 18th century. Watt used the term to help potential buyers of his steam engines understand the power output in a way that was relatable to them.
Democritus and Dalton were the first to believe that all matter was made up of different indivisible elements called atoms. A lot of Dalton's atomic theory from the 1700s is still accepted in modern times.
Why when scientists record a gas volume they also record its temperature?
Scientists record the temperature when measuring gas volume because temperature affects the volume of a gas according to the ideal gas law. As temperature increases, the gas molecules move faster and collide more frequently with the container walls, increasing pressure and volume. Keeping track of temperature allows for accurate calculations and comparisons of gas volumes.
