This is historically correct. One of the older ground based radio nav systems worked like that. Different patterns of dots and dashes if you were R or L of intended path, and when you were on the path they blended into a different tone. I am so glad that I never had to use that system! Another...

The primary non-GPS means of aviation navigation is ground based navigation systems: mainly, VOR and DME. https://en.wikipedia.org/wiki/VOR%2FDME These are stations worldwide that transmit radio signals. Receivers in the airplane tell you what direction the station is (which radial you are on)...

I don't know what B&S recommends, but with most engines as a general rule it starts to make a difference above 5,000. So you should definitely ask, as @c502cid suggests.

With the expensive binocs you're typically paying for big lenses so they don't get too dark in limited light, a wide field of view, and less distortion around the outer edges. For target spotting, you don't need any of that. Your primary use is in daylight conditions and you are only using the...

The CVCC was a neat innovation, described on Wikipedia: https://en.wikipedia.org/wiki/CVCC

I learned to drive with the next model, the first generation Civic (a 1978), 4 speed manual. Driving down the freeway in top gear at 60 mph you would swear the engine was about to explode. https://en.wikipedia.org/wiki/Honda_Civic_(first_generation) It was reliable for its time, but didn't last...

Not necessarily, it depends on the watch. For example I find the Miyota 9015 movement to be more reliable and consistent than some of the Swiss movements such the ETA 2824.

True, and in this case it doesn't. It produces a small forward thrust, which is less than the power it receives from the wheels. It doesn't take 100% efficiency, it only takes something greater than 0. Ponder this: it's well known that sailboats can move downwind faster than the wind.

If it a simple positive feedback loop, it would be a perpetual motion machine. But it's not. There is no net gain. The prop is geared to and powered by the wheels. So power at the prop is equal to power at the wheels, minus losses. The wind pushes on the cart, powering the wheels, and the...

Different people get this in different ways. I can't see it being positive feedback because that opens the question why isn't it a perpetual motion machine? Or as @WobblyElvis says, if you push it to get it started in no-wind conditions, it won't run. It does require wind to push it. At first I...

Sure, but a sailboat's fastest point of sail is not generally directly downwind. Not even close to that, but roughly perpendicular to the wind. https://sailawayblog.com/fastest-point-of-sail/ And that means your fastest point of sail is not necessarily in the direction you want to go. So...

That is a freaky and wonderful example of how even simple things can be counterintuitive. The universe is stranger than we think.

If you're already short in a position, selling a put on it is considered "covered". Either way, you better have cash on hand in case the puts exercise.

Even naked options can be, but aren't necessarily, high risk. They can also be used to reduce risk. For example, selling naked puts. Suppose you want to buy a stock that's currently trading at $50. You'd like to buy it at $45, so sell a naked put with a strike of $45. Now you pocket the premium...

True, but they don't tell you that in this sentence the word "performance" refers to their financials/profits, not the engine. ;) Use any oil that meet their specification, which is broad enough to cover almost every 0w20, 0w30, 5w20 and 5w30 oil on the shelf at your local auto parts store...

Plenty of advice & instruction on this topic online, and you should seek out varying professional opinions on this. Years ago I used to trade options, it was fun, educational and profitable. But like @ArrestMeRedZ , over time I realized I could do just as well with other investments that are...

Yes, almost. But it was an all-day thing because the grass was so tall I had to do a pass with a hand-push two-wheel weed wacker first, before mowing it.

Yep, you read that correctly.

I bought a Craftsman push mower powered by a Honda 160 back in 2004, so it's 20 years old. Still going strong. Over the years I've replaced the carburetor and spark plug, and changed the oil a few times, but that's about it. I used to mow about 3 acres of grass with it, so it's got a lot of hours.

Incorrect. The question explicitly ties the new schedule to Ms. Oliver by saying, "the new schedule calls for Ms. Oliver's work hours to be 8:30am..."
