Why is there no friction on ice? One of these theories is that friction causes the liquid layer of water to form on ice. Friction is the force that generates heat whenever two objects slide against each other. If you stand on ice without moving, no friction exists to generate heat, yet the ice is […]
What time of day is oxygen highest?
What time of day is oxygen highest? Even though there is an increase in carbon dioxide through the daytime on your block, oxygen is much more present at the beginning of the day.

Does higher voltage mean higher current?
Does higher voltage mean higher current? Hence, the specific answer to your question is no. High voltages do not equal high currents. Voltage and current move inversely to each other. Higher voltage means lower current, and vice-versa. How does voltage affect speed? Back to the original question: how does voltage affect speed? From the analysis […]
What is the charge of the nucleus of an oxygen atom?
What is the charge of the nucleus of an oxygen atom? +8 Are electrons found in the nucleus? Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus. […]
What is significance of uncertainty principle in our daily life?
What is significance of uncertainty principle in our daily life? The Principle says that the position and the velocity of an object cannot both be measured exactly at the same time. At the size of objects seen in everyday life, such as a car, the Uncertainty Principle has no real application. We can accurately measure […]

When a substance is boiling Will the added heat increase its temperature?
When a substance is boiling Will the added heat increase its temperature? Adding heat, however, does not always increase the temperature. For instance, when water is boiling, adding heat does not increase its temperature. This happens at the boiling temperature of every substance that can vaporize. What are the 4 conditions which allow bacteria to […]

Who is the father of model theory?
Who is the father of model theory? Tarski’s work included logical consequence, deductive systems, the algebra of logic, the theory of definability, and the semantic definition of truth, among other topics. His semantic methods culminated in the model theory he and a number of his Berkeley students developed in the 1950s and ’60s. What is […]
