Answer these and get 10 Points?

Question

1) Why Does a physicist have to know how to operate instruments?

2) How does the knowledge of mathematics help a physicit?

3) Give Some Examples of application of Physics.

4)Given the units s, m/s , J, W , kg, A, V , m , m(3), candela, N/m(2) , C, Mole, farad , K, group themas basic units and derived units.

5) The standard units of some quantities have been changed so many times in the past. What could be the reason?

Answer 1

A1) If u have to prove that u know to drive bike than wat would u do?... U will drive the bike in front of them. Similiarly a physics is al about laws and if u r a true physicist and have to prove yourself than u need to know how to operate instruments. This is a very crude example but to explain my point i used it.

A2) Obviously knowledge of maths help in every field even in operation theatre while doing operation. Many laws of physics can be proven only by using higher level of Maths like calculus and exponential curve theory.

A3) Appilication of physics is everywhere, in each and every task u perform. When u kick ur bike u r applyin force, and if u apply the force at right angle(90 degree) than ur bike will start even with less effort. And by chance u missed the angle u might end up with ur leg break.

Other ex: Chopping of vegetables, ur walk-run, everything...

A4) -----

A5) For uniformity. For example, if i say its 4 O'clock evening and u say its 16 hrs, than though we both r right but we lack uniformity. Similary in physics, there is a committee of scientist including people from al over the world. Sometimes these peoples did agree to same unit so to resolve they derive a new unit on which all give there consent and this is how units change.

Answer 2

1)Instruments are the means to Record observations in the experiments a Physicist performs 2) Mathematics is the heart of Physics. It is the most elementary and a primary tool to proceed in his research work. All his models/idealising need to be developed using mathematics. 3) One direct consequence of physics is Strength of Materials. This is the basic applied science for all engineering structures to design the sections to resist loads with adequate safety margins for most adverse conditions.4)Basic units-mass(m),Time(s),
Cadela(luminosity),Mole(Amount of substance),
Deg Kelvin(K) -Rest are all derived units
5) Originally Hydrogen was standard
for atomic weight. Later it was oxygen.
Finally it is now carbon12 relative
which all other atomic weights are fixed,
It is basically ease of reference and
stability of the reference chosen

Answer 3

Here are the answers you are looking for. Gimme my 10 points.

1) Because then he wouldn't be a physicist
2) Because he has to be able to do his taxes
3) Gravity, velocity, corned beef hash
4) Basic units - units with a pH greater than 7; Derived units, units you make up.
5) Because the French can't make up their minds.

Answer 4

Man, I'm gullible. I thought you were interested in math/science. Just busting some ballz with this Q. You want us to do your homework! Get real. Thats worth way more than 10 points. I'll settle for 2.

Answer 5

1) otherwise how will he work in the lab.
2)mathematics is a branch with importance seen in evry subject . physics is called exact science because we need to take out the exct values in it. therfore mathematics helps physicist
3) you may find it in google
4)i can't understand your question
5)because newq reseaches have taken place that give better results.

Answer 6

Kentucky Boy has extra teeth than the entire city . anybody contained in the small city of Doubledown, KY are out to shoot to kill Bubba Bitesdouble for his teeth, in spite of the indisputable fact that the interior sight city Sheriff will hunt him down first.

Answer 7

ill stick with 2

Answer 8

You sure require a lot for your 10 points! Come on give us a little break!!! ;o)

Answer 9

I don't think anyone is that hard up for points. Try offering cash.... or just do your own homework.

Answer 10

I didn't understand a word of that, but try C when in doubt.
