It was the investigator J. J. Thomson who did experiments with an early cathode ray tube. You'll find a link below.
John Dalton conducted experiments on chemical reactions involving gases, specifically combining different gases in fixed ratios. Through his experiments, he observed that elements combine in small, whole-number ratios to form compounds, which eventually led to the development of the law of multiple proportions.
Rumford's experiments showed that heat is a form of energy that can be produced indefinitely and is not a substance. Joule's experiments demonstrated the relationship between mechanical work and heat, leading to the theory of the conservation of energy. Together, these experiments helped establish the concept of thermal energy as a form of kinetic energy and laid the foundation for the modern understanding of the nature of heat.
In electroplating, the anode is the positively charged electrode that supplies metal ions to be deposited onto the cathode (the negatively charged electrode). As the electric current flows through the electrolyte solution, metal ions from the anode are attracted to the cathode where they are reduced and form a thin layer of metal coating.
Light can be proven to be a form of energy through various experiments, such as the photoelectric effect or the emission of photons in certain chemical reactions. These experiments have shown that light carries energy and can exert forces on objects it interacts with, demonstrating its energy properties. Additionally, the relationship between light frequency and energy as described by the equation E=hf further supports the concept of light as a form of energy.
The Law of Conservation of Energy is supported by various experimental observations and studies in physics. Energy cannot be created or destroyed, only converted from one form to another. This principle has been validated through countless experiments, such as those involving the conservation of mechanical energy in simple pendulum systems or the conversion of potential energy to kinetic energy in falling objects.
J.J. Thomson used cathode ray tubes to prove the existence of electrons.
Record the data and form a conclusion based on the results.
no . . . . . . plural for scientist is scientists.
The plural possessive is experiments'.
Metals typically form at the cathode during electrolysis. This is because positively charged metal ions are attracted to the negatively charged cathode where they gain electrons and deposit as solid metal.
To answer a specific question, scientist form a hypothesis. If the hypothesis cannot be testable or answered, they'll give you a prediction of what will most likely happen from the results of the hypothesis.
a cathode ray reader is a device that can recognize beams of electrons in analog form and interpret them into digital form
What happens is Scientists conduct experiments and if all the Scientists who conducted the same experiment come up with the same results, the call it a LAW.
The plural possessive form of "experiments" is "experiments'".
Students could be seen to be acting as scientist if they are following the scientific method - Make observations, postulate a hypothesis, and form and complete experiments or further observations to confirm or refute that hypothesis.
Cathode rays are the emission of free electrons form the negative pole of an electric circuit. To get this to happen you need to warm the cathode and place it in a vacuum tube with a high voltage across it. The electron then jump form the cathode and fly across the empty tube to the anode (positive end). They may be bent by magnetic fields in flight.
