Why do wires get hot resistance? Heating a metal conductor makes it more difficult for electricity to flow through it. These collisions cause resistance and generate heat. Heating the metal conductor causes atoms to vibrate more, which in turn makes it more difficult for the electrons to flow, increasing resistance. What causes low resistance in […]

What helps breathing at high altitudes?
What helps breathing at high altitudes? Once you’ve mastered the belly breath, you can add resistance to your exhalation by pursing your lips and exhaling forcefully, and this is what mountaineers call the Pressure Breath. This is one of the most important breaths for climbing at high altitudes and helps combat the decrease in atmospheric […]
Is bread reversible or irreversible?
Is bread reversible or irreversible? Matthew Johnson, Math major and autodidact. Unless you consider ‘toast’ bread that was simply warmed and not toasted (which I call ‘raw toast’), then clearly it is irreversible. You have by toasting changed the chemistry in an irreversible way. Heat making chemical changes is not “infinitely close to equilibrium”. Is […]
Which method best helps to prevent wind erosion rotating crops?
Which method best helps to prevent wind erosion rotating crops? Conservation tillage is one of the best methods for preventing damage from wind erosion. No-till, ridge-till, slot-till, and other tillage systems that minimize disturbance of the soil during field preparation and planting are proven techniques for controlling wind erosion. How can you help conserve and […]
What are the main types of roots?
What are the main types of roots? Plants have three types of root systems: 1.) taproot, with a main taproot that is larger and grows faster than the branch roots; 2.) fibrous, with all roots about the same size; 3.) adventitious, roots that form on any plant part other than the roots. What are 2 […]
What kind of waves are the sound waves?
What kind of waves are the sound waves? So what type of wave is sound? Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves. Why is longshore drift bad?
