Physics: Thermal Expansion?

In a certain experiment, a small radioactive source must move at selected, extremely slow speedsThis motion is accomplished by fastening the source to one end of an aluminum rod and heating the central section of the rod in a controlled wayIf the effective heated section of the rod has length d 2.00 cm, at what constant rate must the temperature of the rod be changed if the source is to move at a constant speed of 100 nm/s?The answer is 0.217 K/s but I don't know how to get this answer

It sounds like you are both just holding on to each other as if things fall apart she or he is there to comfort,,It also sounds like you have learnt allot of things along the way of your journeyIf you both where Very serious about each other then you would have respect for your others partners feelings and face the facts of what you are doingIf you are serious and mature you would both be together by now, the only fact is that you are both scared of that if you told the truth, and told your other partners of what is happening, you fear the outcome, and would the enjoyment of secrecy go awayIts your journey and only you can decide what is best.take care

wowthis is weirdi dont know what her intentions areall i know is that when i was involved with a married man, he actually left his wife for me (though i didnt want him to, but HE fell in love with ME and insisted it was the best thing to do)anyway, i eventually left him brokenhearted because i wasnt happy with him and he is now stuck with a nasty divorcewhy do we get ourselves into these sticky messes? i dont knowi think she is not someone you should have ever gotten involved withwhat did you think was going to happen, and what DO you think will happen? well, i think, she may not leave her husband and will either keep you hanging for a few more years or she'll break your heart like she'll be doing to her husbandif she eventually leaves him and gets with you, u will end up in a broken relationship because you'll never be able to trust heryou'll always wonder if you are the husband she is messing around on with other guysis SHE in love with YOU? Does she want to be with you? U need to have a heart to heart with herBut it sure sounds like she is TroubleWhat kind of a woman does this to her man?

Do you do other risky things sexually as well? Do you find you take more risks than the average person in other areas of your life? Do you enjoy extreme sports or other high arousal activities? If so this could be part of a larger pattern due to a high physiological threshold for stimulation (that's one theory for some antisocial behaviors)Ordinary activities, or ordinary sexual activities, may not stimulate you as much as something risky or forbiddenOn the other hand, if you find this type of behavior is almost exclusively limited to sleeping with married women then the explanation is likely very differentIt could be a fetish loosely related to past experiences or cyclical cognitive patternsIt would require a much more in depth analysis if this were the caseEvolutionarily speaking, sleeping with another man's wife and getting away with it is the ultimate prizeIt provides the opportunity to have a child that another man raises with his resources, leaving the true father free to have many more childrenWhether or not birth control is used is irrelevent; theoretically this is an instinctual trait that has evolved over many generationsWhat would cause that drive to be more active in you and less active in others remains unexplained.

I'm not quite sure what your question is askingMaybe my example below will help you outAluminum has a specific heat of 0.902 J/g x oC How much heat is lost when a piece of aluminum with a mass of 23.984 g cools from a temperature of 415.0 oC to a temperature of 22.0 oC? Step 1: First read the question and try to understand what they are asking youCan you picture a piece of aluminum foil that is taken out of an ovenImagine the aluminum losing heat to its surroundings until the temperature goes from 415.0 oC to 22.0 oCStep 2: Write the original formulaq m(DT)Cp Step 3: List the known and unknown factors Looking at the units in the word problem will help you determine which is whichq ? m 23.984 g DT (415.0 oC - 22.0 oC) 393.0 oC (remember, they asked for the change in temperature) Cp 0.902 J/g x oC Step 4Substitute your values into the formula q ? m 23.984 g DT (415.0 oC - 22.0 oC) 393.0 oC Cp 0.902 J/g x oC q m(DT)Cp q 23.984 g x 393.0 oC x 0.902 J/g x oC Step 5Cross out units where possible, and solve for unknownq 23.984 g x 393.0 oC x 0.902 J/g x oC q 8501.992224 J Step 6Round to the correct number of significant digits and check to see that you answer makes senseq 8.50 x 103 J
