What is a Doplar Effect?
The doplar effect is like when you are standing on the sidewalk and you hear a car coming, see it pass and then hear it leaving. As it approaches, the sound builds gradually and increases in pitch, and after it passes you, it drops quickly in pitch. This is because as the car is approaching you, each sound wave has a shorter distance to travel to your ear than the first one, and as a result they "smush" each other together, shortening the wavelength and increasing the pitch.

If the doctor doesn't detect heart in six weeks of pregnancy is anything wrong with pregnancy?
Normally a fetus heartbeat is not heard until 10-12 weeks with a doplar ultrasound device. With a stethoscope somewhere around the 17-18 weeks. 6 weeks is very early to be detecting a heartbeat! Good Luck!
What does a dolpar radar measure in units?
Do you mean Doppler radar? If so, Doppler radar measures velocity. It's a specialized radar that makes use of the Doppler effect to produce velocity data about objects at a distance. It does this by beaming a microwave signal towards a desired target and listening for its reflection, then analyzing how the frequency of the returned signal has been altered by the object's motion. This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to the radar. Doppler radars are used in aviation, sounding satellites, meteorology, police speed guns, and radiology. The specific term "Doppler Radar", due in part to its extremely common use by television meteorologists in on-air weather reporting, has erroneously become popularly synonymous with the type of radar used in meteorology. Most modern weather radars use the pulse-Doppler technique to examine the motion of precipitation, but it is only a part of the processing of their data. So, while these radars use a highly specialized form of Doppler radar, the term is much broader in its meaning and its applications.
What are two kinds of information that astronomers can collect from stars by using spectrographs?
All elements have their own discrete power spectra. To excite a hydrogen atom requires a different amount of energy than to excite a helium atom. The energy of a photon is proportional to its wavelength. So by looking at the wavelengths in the absorption or emission lines in the spectra and comparing them to known energy levels (empirical or quantum mechanic derived) of different elements, a great deal can be said about a stars outer layer.
Recognizing Mild Stroke Symptoms?
Mild stroke symptoms are a warning sign that there is a larger problem lingering in your body. Also known as a transient ischemic attack or TIA, the sudden presence of numbness or weakness in the facial area is cause for alarm but when the feeling begins to dissipate, most people shrug it off. Other signs that a TIA is taking place are:Unrecognized severe headacheLoss of balance when standing or walkingConfusion of your surroundingsTrouble speaking wordsVisual changesSudden numbness in arms or legsDizzinessLoss of feeling on one side of the bodyBecause joint pain and the slowing down of metabolism occurs as people age, many dismiss the signs of a mild stroke as an expected part of aging. While the thought of a TMI may cross your mind it usually is not intense enough to drive a person to seek immediate medical care. What if it is not a mild stroke? No one wants to over react and rush to the emergency room.However, ignoring the signs of a mild stroke can have permanent, life altering consequences if treatment is delayed. Never question a visit to an emergency room immediately after having a TIA so steps can be taken to prevent a larger stroke in the future. A blood clot that has formed can be destroyed by a clot-bursting drug if administered within 4 1/2 hours of the mild stroke. Tests like a Doplar ultrasound can be performed to identify the cause or an MRI may be ordered to evaluate the damage done.According to one stroke specialist, 32,000 brain cells are destroyed every second while experiencing a TIA. By receiving treatment as soon as possible you can deter this kind of loss. Never wait until the following day to see a family physician as a precaution. By taking action immediately after a TIA has occured, your chances for heading off a major stroke in the future are decreased significantly.

Is the Samsung Delve cell phone a quality cell phone?
The Samsung R800 "Delve" is a touchscreen cell phone offered by Alltel & U.S. Cellular. This phone has been said to get bad reception. Other than that it is made by a quality manufacturer and is a quality phone. I recently purchased the samsung delve sch r800, I absolutely love it my service provider is Alltell I had centennial wireless, Sprint/nextel, and the delve is the best reception I have ever had with a cell phone. The downside is it does not rotate the screen as you rotate the phone like an iPhone does but all in all I will never own another cell phone without a touch screen. it has a couple cool features such as writing recognition for text messages, you just write on the screen and it types the corresponding letter. it also has widgets on the main screen which holds weather a writng pad for quick notes or u can draw a picture (great for the kids to keep busy or a quick shopping list. u can also draw on your pictures u take with the phone, no flash is a drawback as well. the web browser is not wi fi so it is a little slow but not bad. it features email on demand tv with about fifteen channels ie. discovery, spike,vh1,MTV,usa, bravo,fox sports, nbc sports,access Hollywood, sci fi,cmt,telemundo,nbc comedy, nick, TLC, animal planet, ign, a heros ch,comedy central,atom films,accuweather,tr3s, to name a few there is more than this just make sure u get the phone plan that has unlimited data!! otherwise it will charge u to get online and watch tv. some of the channels are live feeds but for the most part they have sub folders with hundreds of episodes in each one for each channel/and each show. that's bad ass. it also has a lady's voice that tells u who is calling via caller id and what namwe u have them stored under, ie; she says call from Shawn eastgetup so if the phone is in your pocket and u have your bluetooth in your ear u can decide weather or not to answer it without looking at ur phone. u can add a memory card in the slot provided up to 8 gb's and the phone comes with 143 mb's internal memory.it also comes with a free alltel navigation for voice comanded turn by turn directions while traveling. In the main menu under settings u can check for phone updates anytime u want so lets say your provider upgraded the web browser for all of their phones u can just select check for updates and it will tell u if any are availabe, u can do this anytime u want to. it also has voice recognition for your voice commands to open menu options, voice dialing, it is powered by nuance communications, very nice options u can do anything the phone has to offer without touching the phone at all. the weather widget has live doplar radar and u can add as many locations for curren weather or forcasts. it also has a nice video camera that allows u to film 3 seconds, 10second, or an hour of video at a time the camera is a 2 mega pixel but takes great pics and video , it has as many options as my personal cannon 40D as far as settings white balancing mosaic, and so on, so I hope this helps u out and have a great Easter and remember the samsung delve sch r800 is all out rediculous. and Alltel is great they also offer a 30 day trial with any phone as many times u want if u find u don't like it just return it no questions asked and try the blackberry pearl or whatever, if u don't like that return it before ur 30 days are up until u find the one u desire, i highly recomend the first purchs u have to get is a screen saver it saves ur screen from being scratched also get a leather case for it that has a stylis holder as the phone itself does not have one. enjoy, sincerely, djty777
