What is the cause of resistance? Resistance is caused in a conductor by the free electrons. These free electrons collide with each other and with the ions and atoms that oppose their free movement. This obstruction is known as resistance. Does temperature increase resistance? As electrons move through a metal conductor, some collide with atoms, […]
What is considered a strong wind for cycling?
What is considered a strong wind for cycling? 35-40 mph or more and I would begin to consider staying in. Around here if we didn’t ride in 20-30+mph winds …well…then we wouldn’t ride much. 35-40 mph or more and I would begin to consider staying in. How much wind is considered windy? According to the […]

How does the kinetic theory explain Charles Law?
How does the kinetic theory explain Charles Law? Kinetic Molecular Theory states that gas particles are in constant motion and exhibit perfectly elastic collisions. Kinetic Molecular Theory can be used to explain both Charles’ and Boyle’s Laws. The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only. What […]
At what temperature does all motion cease theoretically?
At what temperature does all motion cease theoretically? A temperature scale whose zero point is absolute zero, the temperature of 0 entropy at which all molecular motion stops, -273.15° C. The size of a degree Kelvin is the same as the size of a degree Celsius. Which temperature does all molecular motion steps? Step by […]
What are the three main parts of a chemical reaction?
What are the three main parts of a chemical reaction? A chemical equation shows the starting compound(s)—the reactants—on the left and the final compound(s)—the products—on the right, separated by an arrow. What are the two types of chemical reactions? Types of Chemical Reactions: Single- and Double-Displacement Reactions Recognize chemical reactions as single-replacement reactions and double-replacement […]
Is the right to act in certain designated ways to directly influence others?
Is the right to act in certain designated ways to directly influence others? Authority is the right to perform or command. It allows its holder to act in certain designated ways and to directly influence the actions of others through orders. Which one of the following is a key difference between managerial and nonmanagerial employees? […]
How many times more light can the telescope gather than the human eye?
How many times more light can the telescope gather than the human eye? So the telescope can gather light for 900 times longer than the eye, to make a single image! The long exposure time of the telescope’s camera enables it to gather much more light than the eye. This enables telescopes to detect much […]
Why does the government have to pay to sustain green energy?
Why does the government have to pay to sustain green energy? There are a few common reasons used to justify a government role in renewable energy investment, including energy security and affordability, the potential for job creation, future economic strategic positioning, and addressing environmental and other externalities. What are the best renewable energy stocks? Renewable […]
