At 85 dB you'll have hearing damage from long term exposure without hearing protection. Normally considered 8 hours a day 5 days a week. So 2000 hours in a year. Higher sound levels have a lower threshold so shorter times. 120 dB is the threshold of pain, so immediate hearing damage. Also, dB are a 10x log scale. So every 10 dB is an order of magnitude increase. So the siren is actually about 3000x louder than when you should start wearing earpro.

Nah, FL5 Type 5 has hill assist, rev match, anti stall, and brake lock. With really comfy bucket seats. At speed you got Honda's bitchin adaptive cruise control and lane keeping assist. It's as comfortable as a manual car can be for commuting and traffic. 10/10 would recommend as daily driver.

If you use "natural" or "organic" peanut butter (read, ingredients: peanuts) you'll want to refrigerate it. It helps keep the oil from separating. It'll be the consistency of jiff or other sugared brands for most of the jar. I usually take mine out of the fridge when you get towards the bottom so it doesn't get too hard.

Since when has Quebec been in Europe?

Not really. Radio power decreases with the square of the distance. So at if "blackout" is at 10 feet then at 100 feet your at 1% of your original power. So realisticly your blocking your GPS signal and partially obstructing signals for 2-3 cars adjacent to you and likely less than that. You wouldn't be reaching any planes without a lot of power and a big transmitter.

Planes avionics are more then sufficient to navigate and fly the plane without GPS. And planes will most definitely land without GPS as a.) GPS isn't the predominant tool for altimetry and b.) a plane has to land or it will crash. GPS is primarily used for navigation of routes and most critically for planning approaches and landings. It enables the tower to send an approach plan directly to a plane. So, really important for packing the skies with planes, but a malfunctioning gps unit isn't going to stop a plane from landing at its designated airport. May stop one from taking off though. This really only applies to big planes. Small planes don't always have gps and don't always land at airports using gps. Still really nice to have so you don't get lost, though.

Accurate GPS is a fairly recent luxury as until the 90s it was made inaccurate by design as only the military could access the full radio spectrum, and only recently has the full constellation of current gen sats been fully deployed. Also interestingly commercial gps receivers won't function beyond 600 mph and/or 60 000 ft to prevent people from using them for missiles. Military ones (in missiles) or if you home brewed it won't have this restriction though.

You are right though. Running a jammer is illegal as hell and you can really fuck other people's day. Especially do not try bring a jammer on a plane. They monitor radio very closely at and around airports. You will be caught and you will be sent to federal "pound me in the ass" prison.

It have suicide doors? God I miss those. Terrible for passenger safety, but I could fit so much stuff into my ion with those. Made moving with a sedan so much easier.

Categorically false. They also bring 5.56x40mm.

It's only arbitrarily easy since water has a density of 1 kg/l in metric, as it was designed to do so. If you happened to know the density of water is 62.2 lb/ft^3 then the equation is roughly 123*60 which is 360 lb. 372 if you can actually paid attention to what common core was trying to teach. If the material was anything other then water the math would be just as difficult to do in imperial or metric.

Metric is still far superior as the harmonized units make density in particular much easier to convert between. About the only thing imperial is better at is thread pitch of screws. I will also maintain that when describing human temperatures for weather Fahrenheit is a superior scale, but that's just more personal preference and experience then any rational basis.

Gauge is historically number of passes through gauging machine. With the machine and material in question being different for every single one. We took that and put it to a standard, so it's super messy and makes no sense.

Cause it's not. It's a knock off of the e-wing, the legends successor to the x wing that wasn't used much cause it kinda sucks. Though it might be in Ashoka now too.

It's not unfair, nor is it misleading. Coal contains a few parts per million of uranium. Sometimes more depending on source. So when burned this uranium is released into the atmosphere. When used for fission uranium has about 200 million times the energy density then burning the carbon carbon bonds in coal. So kilo for kilo a coal power plant dumps about as much uranium and other nasty trace elements into the atmosphere then a nuclear plant has in it's core.

The situation is even more unfavorable for coal as nuke plants don't typically dump any of their primary radioactive elements to atmosphere. Increasing scale of nuclear doesn't change this either as it would require every nuclear plant on the planet to go full Chernobyl just to match what coal outputs.
