What prompted early scientists to propose that the ray of the cathode ray tube was due to the cathode?
The electron had already been discovered. It took little imagination to "see" that the cathode ray was the beam of electrons that originated from the cathode. And the beam was controlled using techniques based directly on what was correctly understood about the electron. The cathode ray could only be an electron beam generated at the cathode. Conventional elctric current flow is usually thought of as flowing from positive to negative, but at the quantum level; due to electrons having a negative charge; technically they really flow from negative to positive, and this is apparent in the cathode ray tube. Its the negatively charged electrons that glow in a cathode ray tube, and do so from the negative terminal, or cathode, hence the name.

Will electrons flow from anode to cathod?
"from anode to cathode". Normally, no. Taking a radio valve (electron tube), since the anode is positive compared to the cathode, and since electrons flow from surplus (at the negative cathode) to deficiency (at the positive anode), they do *not* flow from anode to cathode in normal operation. It's possible to have electrons striking the anode and *knocking off* electrons from it, and then to have those electrons travelling back towards the cathode. This is secondary emission. It was a problem in four-element "tetrode" valves in the early days, but has now been eliminated in practical designs. Long story short: it's possible, but undesirable and not common.
Who was the Kuiper belt named after?
The Kuiper Belt is named after Gerard Kuiper; he was one of the only scientists who had theories about the Kuiper belt in the early fifties
Why do people travel in early times?
In early times, people traveled primarily for trade, seeking new resources and goods to enhance their livelihoods. Exploration was also motivated by curiosity and the desire to discover new lands, cultures, and opportunities. Additionally, migration driven by climate changes, conflicts, or the search for fertile land prompted movement across regions. Travel was essential for survival, cultural exchange, and the development of civilizations.
What did the westward expansion in the early 1800s directly result in debates over?
The westward expansion in the early 1800s directly resulted in debates over the extension of slavery into new territories, as the addition of new states raised questions about whether they would permit slavery or be free states. This contentious issue heightened regional tensions between the North and South, ultimately contributing to political conflicts and the emergence of movements like the Free Soil Party. Additionally, the expansion prompted discussions about Native American rights and sovereignty, leading to forced removals and violent confrontations.
How does social psychology emerge as a discipline in twenth century?
While some of the basic concepts of social psychology were mentioned as early as Plato's time, social psychology as a modern discipline began in earnest after World War II. After the scope of the Holocaust was revealed, social scientists began studying the effects of conformity and obedience on social behavior.
