I haven't read the article, not sure how to access it, so just some thoughts relating to comments:
If the car is an automatic, the transmission will generally be disengaged (apart from its minimal transmission drag) while coasting downhill, so the engine will be idling. You can of course put...
While I don't know what schools, I did some regression analysis in my training. Back when I was working as an analyst programmer in GIS, I had to do a run time optimisation of a data analysis between map layers. This was taking a prohibitively long run time on large data sets. So, I gathered...
I found a short off cut or marine shock chord among bits from my youth 1970s.
It is still in excellent working condition. Unlike the stuff I can buy these days which only lasts 1 or 2 seasons. This still has very high strength & I'd have no hesitation using it if it was a useful length. It...
This may already be covered, I haven't read the entire thread, sorry.
I'm a retired cartographer/analyst programmer working for NSW (Australia) state mapping and geodetic survey authority. The advantage of more points is to determine precision. Precision is not accuracy it is consistency. You...
Um as a sailor with decades experience and placements in both state and national titles, I assure you that you are mistaken, entertainment commentary is not accurate to reality. It is only very high performance boat designs that can sail faster than the wind and even then, only on certain...
The initial error was assuming each bulb draws the same power as it would if it was the only load.
In series the, R increases, therefore current decreases reducing power.
My solution (knowing the 2 bulbs are the same power and impedance, assuming 120V is AC):
R1 = 120^2/(95) = 151.58
R2 = R1
R...
Just a thought:
I've had a lot of reliability issues with USB3 as well. While there can be processing issues. It seem to me to often relate to the electrical connection of the USB3 plugs themselves. A quick spray with Deoxit F5 often does the trick. I suspect there may be small particles...
Fire breaks are the primary bush fire defense strategy in Australia, however they only work in combination with air and ground crews.
If a fire is on the ground, that is burning the dead fall material, that is comparatively less intense heat and lower risk of embers breaching a fire break...
No, I don't have example velocity profiles. I am just going by statements in lectures and technical notes that I have come across over the years. The nature of this is that I do not have references either. I am not insisting anything here, it just seems to me a point of some controversy that I’d...
I have seen a few lectures where a contra view is presented. Who should I believe and why? Certainly, lift can be explained by the pressure gradients across surfaces. Can you mathematically show that those pressure gradients are totally explained by Bernoulli's principle, even for a symmetrical...
I thought that was what was referenced by "circular flow". My understanding is that it isn't actually physically true. That circular flow is just a conceptual model of relative flow velocities once you remove the average flow velocity. I am not convinced the conceptual model is correct at the...
You all realize that there are many examples of electrical devices that output more power than is input.
Just take a reachable battery for example, may take 10 hr to charge & 10 minutes to drain, but in that 10 minutes the power can be an order of magnitude greater than the input power. There...
HI,
My understanding is that Audio is carried as a modulation of the radio wave Carrier frequency, either amplitude modulation (AM) or frequency modulation (FM). In the case of AM, it's easier to visualize the modulation as variations in peak to trough. To put it into the more familiar digital...
A sundial gives solar time. Think of it in those terms. Basically, your local time is calibrated by the sun passing over your local meridian being midday. This is true wherever you are. You may correct this for the difference between local and time zone meridians to obtain the local time...
I think that in most practical situations, it doesn't matter which direction you model the current to run as long as your are consistent with that. Neg to Pos is correct of course but you often see it modeled the other way around. The main thing that matters is the magnitude of the potential...
