Which sounds more impressive, MD or PhD?
They are two different types of degrees. While both are doctorates the MD is called a professional degree and the PhD is a research degree. A professional degree is generally 3-4 years after getting a Bachelor's degree. Professional degrees include the MD, DO (another type of physician), JD (lawyers), Foot doctors -DPM, dentists - DMD or DDS, Chiropractors DC (chiropractic schools may not require a BS),DPharm for pharmacists, or OD for eye doctors is also a first professional degree. There are others but you get the idea... you can start a profession when you finish one of these degrees. On the other hand research degrees like the PhD, DEng for Engineering, DMus for Music, DPH for Public Health require from 7 to 9 years after the completion of the undergraduate or 11 to 13 years of full time study and research. So while the MD may sound like a big deal (and I'm sure it is) the research degrees take much more work to finish. While the doctor may prescribe a drug scientists with PhDs and other research degrees probably discovered, designed, and tested the drug. I know a physician who spent 4 years in Medical School and then got a PhD in Neurobiology in six more years so he spent 12 years in college. (He worked as a physician while doing his PhD.) The links below are from the US Department of Education and explain the difference between first professional and research doctorates.
Why do different bikes make different sounds?
The reason for the sound has to do with the way the engine is designed.A piston goes through the intake, compression, combustion and exhaust strokes every two revolutions of the crankshaft. What you are actually hearing is the sound of the compressed gases in the cylinder escaping when the exhaust valve opens. Each pop is the sound of the exhaust valve opening one time, and it happens on every second revolution of the crankshaft.In a two-cylinder, horizontally opposed engine, the pistons are timed so that one fires on one revolution of the crankshaft and the other fires on the next revolution so one of the two pistons fires on every revolution of the crankshaft. This seems logical and gives the engine a balanced feeling.To create this type of engine, the crankshaft has two separate pins for the connecting rods from the pistons. The pins are 180 degrees apart from one another. Mufflers and exhaust system also plays significant roles in determining different sounds.
The wavelength of two waves are 49 and 50cm at 30 degrees Celsius. How many beats per second will be heard due to these waves?
Well you must have understood in superposition of waves. Beats per second is equal to the difference of the frequencies of the waves. so first we have to calculate the frequencies of both the waves.wavelengths = 0.49m ; 0.50m (given)speed of sound at 273K= 332m/sspeed of sound is directly proportional to the square root of temperature of medium.speed of sound at 303K (30 deggree C)= 332 × √(303/273) = 349.77 m/sf1 = 349.77/0.49= 713.80f2= 349.77/0.50=699.53beats= |f1-f2| = 14so correct answer is 14 beats/ second
The two sources of sound face each other and emit sounds of equal amplitude and equal frequency (302Hz) but 180 degree out of phase..?
The two sources of sound face each other and emit sounds of equal amplitude and equal frequency (302Hz) but 180 degree out of phase. A) For what minimum separation of the two speakers will there be some point at which complete constructive interference occurs. (Assume T= 20 degree C.) B) For what minimum separation of the two speakers will there be some point at which complete destructive interference occurs.
If the two sound waves have the same wavelength in air at the same temperature, what other property must they also have in common?
If you are talking about sound cancellation, the other condition is they must be 180 degrees out of phase.
Grammar: Why is it wrong to say that something is "more better" than something else?
Adjectives ( and sometimes even adverbs) take three forms of degrees of comparison; the Positive Degree, the Comparative Degree and the Superlative Degree.To express the comparative degree, the adjective undergoes a change - either the “-er” suffix is added to its original form ( mostly in the case of monosyllable words, like, “taller” is the comparative degree for “tall”), or the quantifier “more” is added in front of the adjective ( mostly in the case of long adjectives having two or more syllables, like, “more beautiful” is the comparative degree for the adjective, “ beautiful”).For certain words, however, there are totally new words, very different from the original adjective, which do not conform to the above rules, to express the comparative degree.E.g. “Better” is the comparative degree for “Good”“More” is the comparative degree for “Much”The rule is, you have to follow any one of the above rules, depending upon the restrictions, and no combination is allowed.So, when you say, “more better”, more is redundant here, and you are breaking the above convention of not clubbing two comparatives.Therefore the correct sentence should be:“Something is better than something else.”
How do I change the degree of comparison in this sentence, "It is better to strive than to beg"?
The given sentence is in Comparative Degree.In Positive Degree, it will be —To beg is not as/so good as to strive.You can't change it to Superlative Degree because only two things are compared here.An answer to the query —How do I change the degree of comparison in this sentence, "It is better to strive than to beg"?Good luck:-)
Second-Degree Murder VS Involuntary Manslaughter?
"Second-Degree Murder VS Involuntary Manslaughter" and then "I'm asking about VOLUNTARY MANSLAUGHTER VS SECOND DEGREE". Which is it? You have two different questions there. Second degree is "heat of the moment" homicide, where you didn't intend to kill anyone before, but suddenly you now want to kill a person. For example, you come home early from work and find your wife in bed with your neighbor. You had no intention of killing your neighbor before, but upon seeing the two in bed, you bash him repeatedly in the head until he is dead. That is 2nd degree murder. Voluntary manslaughter would be also "heat of the moment", except you had no intention of killing the person, just hurting them, but your actions caused them to die. Example is a bar fight, and you hit a person, he falls, hitting his head on the corner of a table, and dies from the injury. Involuntary manslaughter is when you have no intention to do any harm to a person, but your reckless actions cause it. Drunk driving is an example of that - You do not intent to kill anyone when you get behind the wheel after a few too many to drink, but if you get in an accident and kill someone, your reckless action caused the death of that person.
What should be the degree of comparison used in the following sentence, "The teacher found that nobody had handwriting as good as/better than Swetha's".
The given sentence has expressed the message in two degrees of comparison, the Positive Degree and Comparative Degree.The teacher found that nobody had a handwriting as good as Swetha's - Positive Degree.The teacher found that nobody had a handwriting better than Swetha's - Comparative Degree.These two sentences would lead one to the inevitable conclusion,The teacher found that Swetha had the best handwriting in the class. This is in the Superlative Degree.All the three sentences convey the same meaning, only in different forms or different degrees of comparison.
