Why aren’t people more accepting of nuclear power in the USA?
Basically things like Chernobyl and Fukushima have given nuclear energy a bad wrap. It really only takes one worst case scenario
Why are chemicals in glowsticks considered harmful, but the ones in a glow in the dark wristband are not?
To say it in one breath: Glow-in-the-dark items react against previous exposure to light, whereas glow sticks rely on the chemical reaction of mixing two prepackaged chemicals. That's why you have to
Why do cabbage leaves grow rolled up in a ball where they’re guaranteed not to get any sunlight?
Cabbage are artificially selected and bred. The wild cabbage leaves are not not balled up like that. In fact the cabbage is the same plant as broccoli and cauliflower.
why child support is based on income rather than what a child would need monthly.
Child support is partially based on income. It is also partially based on the number of children and their age, the cost of basic living expenses and school in that general area, and whether or not an
Why are denim jeans both stiflingly uncomfortable in hot weather and freezing in cold weather?
When its too hot you will be hot in jeans. When its too cold you will be too cold in jeans.
Why we don’t generate electricity from sound waves while electricity is needed to produce a sound wave ?
We do generate electricity from sound waves. That's how a microphone works. The problem is that sound isn't powerful enough to create a enough electricity to be useful for anything other than capturin
Why does salt cause corrosion on hard surfaces such as concrete?
Salt lowers the freezing point of water and will allow liquid brine to fill tiny cracks in the material. Then as it becomes diluted the freezing temperature rises and the water will freeze, forcing th
Why is the nomenclature for “permanganate” so different than the usual nomenclature for polyatomic anions?
If I recall my chemistry correctly the per- prefix signifies that it is as oxidised as it can be.
why does a car battery die if you leave your head lights on over night, but it can last no problem driving 12 hours straight/through the night with the head lights on and music playing?
Because you have an alternator that powers the systems while the car is running. When the car is off, it's draining the battery.
why do mosfets have Gate, Drain and Source rather than Base, Collector and Emitter?
In a transistor with a Base, Collector and Emitter, a small current is used to control a larger current, essentially copying the small current, but *larger*--thus, the transistor amplifies a faint sig
