A. It is 100%.
B. It depends on the difference between the exhaust and intake temperatures.
C. It depends on the ratio between the exhaust and intake temperatures.
D. It depends on the intake temperature.What is true of the maximum possible efficiency of a heat engine?
A heat engine can never be 100% efficent. The equation for efficiency is 1-Tl/Th
Or Th-Tl/Th
Tl= Temp low
Th=Temp high
Hope this gives you enough information to make the right decision.What is true of the maximum possible efficiency of a heat engine?
It's not A, as that would violate the 2nd law of thermodynamics. Assuming it's a simple engine, it's probably C, but don't quote me on that. My undergrad thermo is a bit rusty.

Is it true it true for Eryctile dysfunction the best method of treatment is shot to the penis that gets it up?
boston medical group has it, i heard it works like a charmIs it true it true for Eryctile dysfunction the best method of treatment is shot to the penis that gets it up?
It depends on many other thingsIs it true it true for Eryctile dysfunction the best method of treatment is shot to the penis that gets it up?
It's all in the mind, it's all in the mind. If a person's losing an erection it's because they're trying too hard or their mind is some where else. Just relax, enjoy the moment, take your time and have an understanding, patient partner. And besides there are numerous products, orally or topically, that can help that problem.

Is it true that cut onions absorb dirt and hence, should not be kept for long?
Some people say eating onions cut even an hour ago and left in the open can make you sick. Is this correct?Is it true that cut onions absorb dirt and hence, should not be kept for long?
Onions don't ';absorb dirt';. However, they have a relatively high sugar content, and so attract microbes at a higher rate than some other foods. Some of those microbes could make you ill if they have multiplied to sufficient quantity (unlikely in as short as an hour, but theoretically possible under the right mix of circumstances). The way to avoid this is to cover the cut surface of the leftover onion as soon as possible to keep the microbes out. Refrigeration also helps. The handling of onions is no different than any other safe-food-handling practice.Is it true that cut onions absorb dirt and hence, should not be kept for long?
If it was securely covered after being cut (put in a sandwich bag with almost no air trapped in it, covered with plastic wrap, etc.) and refrigerated, an onion is safe to eat *days* later. We do this all the time.
What?Absorb dirt....who have you been listening to....some bad advice.
But,yes after cutting,cover and place in frig.up to approx.5 days.
any cut fruit/vegetable left uncovered for a longer time should not b eaten
No its not true. Its best to store them, but it wont make you sick even the next day
not that i no of. ive never heard that before

Is it true that Charmin toilet roll can block your toilet?
Has it happened to anyone? I've heard a couple of people say this.Is it true that Charmin toilet roll can block your toilet?
in can but it definitely will block up a septic system. Been there several timesIs it true that Charmin toilet roll can block your toilet?
It really depends more on how much you put in the toilet, not what brand you use. I would be safe in saying if you put a roll of any toilet paper in the toilet, it would stop it up.
I have never had a problem with it.
didnt know this
That's like asking if you flush a bath towel, will it clog. TP is TP, if you use enough at one time, its all possible.
It used to, but they made it less thick and now it doesnt.fashion necklace

Is it true that twins can feel each others physical pain?
I have heard lots of stories about twins being able to feel each others pain. For instance, if one twin cuts their hand the other will feel it too. I was just wondering if there was any scientific reason for this or if it is just a really weird coincidence. Any answers given will be appreciated!Is it true that twins can feel each others physical pain?
Hiya,
I don't really know an awful lot about this topic but i have found some stuff on the net that may be useful...

xIs it true that twins can feel each others physical pain?
thats NOT true! i have an ';identical'; twin %26amp; our perosnalities are different, same with our interests. i dont feel sympathy for her problems nor vise-versa. i even know another set of identicals that are different
even twins, have different genes. impossible to be exactly the same
we're separate persons, not duplicates
Hey I am a twin and yes some would say we are identical but others say we are non identical. My mother says we are non identical but have similarities
I would say I cannot feel her pain when she gets injured alot but when we were younger. if she cut herslf I would find I would get a similar cut some days later by accident of course. My mum was always in Accident and Emmergency.
well.. i dont reli know 2bh but i dont believe they do because even though they are twins, there are no 2 people in this world that are alike...
I don understand how yu can feel sum1's physical pain when yu are unique...If it's tru that they do, they that's totally weird..

Is it true that used coffee grinds are good for the pipes in your house?
Does it depend on the type of pipes you have, the type of coffee, or the climate? Wouldn't coffee grinds clog your pipes?Is it true that used coffee grinds are good for the pipes in your house?
As long as you don't have a garbage disposal it's fine. Coffee grounds act like sand in a disposal, will ruin it.Is it true that used coffee grinds are good for the pipes in your house?
I've heard of coffee grounds for composting but not for pipes. It wouldn't hurt if a small amount got in the pipes but it would cause a clog if you put alot down the drain.
Yep...plumbers love coffee grinds. They stick to the goo inside your pipes and plug it up or slow down the draining. If you want to use them for something....spread them out over your lawn or put them in your garden.
YES

Is it true that Electrical Engineering major has to devote a lot of time to study?
Is it true that Electrical Engineering major has to devote a lot of time to study? Do a lot of technical stuff instead of enjoying the fun of it? Which one is spent more time on, calculation or hands-on building? Does the planning part also occupy more?
Really want to know more about electrical engineering. Want to know what electrical engineers do both in general and in specific.Is it true that Electrical Engineering major has to devote a lot of time to study?
ALL majors require a lot of study.
that is the definition of ';going to school';.Is it true that Electrical Engineering major has to devote a lot of time to study?
Yes, electrical and every other type of engineering requires a lot of study. If you want to have more fun time, major in psychology or sociology.
The bottom line is that engineering requires a lot of work. Electrical engineers are involved in many things from electricity generation to basic research on quantum computing. There are too many areas to list.
The upside of engineering is that it pays well for people who have a talent for mathematics and science.
Yes, you do have to study alot.
What you consider to be fun is a personal perspective. I enjoyed both the abstract and hands-on portions of my education.
You spend more time on calculations, but it will give you a better understanding of what you are building. Anyone can put together a circuit that is published in an applications note, but it is more fun to design it yourself.
I am a EE, and I spend most of my time programming microprocessors, FPGAs and designing electronic systems.
Also, in deference to what the retired engineer said, engineering does NOT pay very well compared to the other professions (doctor, lawyers, etc). If you want to compare yourself to the average joe-sixpack, you will look well paid. Do the math and see how engineering salaries have been stagnant/declining in real-dollar terms. You can thank offshoring and H1-B visas for that.
Electrical Engineering is almost the same as studying the other fields of engineering. But the thing is, you are dealing with a natural phenomena that is not visible to our naked eye. I am talking about electricity. Electricity is a mysterious behavior of nature. Isn't it a wonderful and exciting thing to study and to analyze and prove the existence of this phenomena? Try not to worry about the time and effort you're gonna use in taking up this course, besides all things about electrical engineering is quite fun to study with!
Yes, my good friend spent a lot of his time in college studying. It is very technical. It's easily 60%+ calculation. If you want to do more hands on engineering, look at mechanical.
My friend works at Cisco managing networks for clients. You can do a lot of different things from chip fabrication to sales.

The technology majors do more hands-on stuff (and make less money in the long run). If making less money isn't a deal breaker for you, look into engineering technology degrees. Otherwise, be prepared to devote insane amounts of time toward studying and doing homework in ANY engineering major.
Well in any major would require you to study. But that doesn't mean u have to sacrifice your fun. In-fact if you like subjects like physics , mathematics etc. You will enjoy the learning. You can be into some really cool stuff like robot building, and some project work. You get the most pleasure in putting your ideas to test and see it work.
Well you need to be both at calculation and hands on building and it is your preference to decide which one you will do more but you just cant neglect anyone.after all no work is possible without calculation and calculation useless if not implemented.all engineers do plan a lot and it is also fun.If you get the basics right you wont fell the major that hard.
Electrical engineers work in power sectors and industries. Some also work in computers, electronics and stuff.
they are mostly involved in planning, organizing, maintainanence and responsible for operations of various units they work on.The upside is that you get paid well and there is always a demand for electrical engineers in the market.
and the schedule is not that hectic as people say.I do robotics(its really fun),programming and all other extra stuff in my school but still have plenty of time left.i go to the beach on weekends,party with friends, go to theaters and hang around with friends.But yes I can say that with some majors you get a lot of free time.
To get a clearer picture I would suggest you to visit a industry and talk to an electrical engineer.
