#AdvancedPhysics

[komalbrainfoster]

Our Physics Tuition program serves students from secondary school to A Levels, with onsite and online lessons available. Focusing intensely on concept clarity, practice, and exam preparation, we enable students to develop a firm foundation in Physics.

Ci dev'essere una spiegazione migliore del modello standard e più comprensibile delle Stringhe. La supersimmetria mi ispira ma non è ancora sufficientemente immediata. Dev'essere una di quelle cose che quando le capisci ti batti una mano sulla fronte esclamando «Ovvio!» e domandandoti come potessi non averla vista prima

Week 36-37: February 16-27

In these weeks we just reviewed our lessons in Physics for the upcoming National Achievement Test.

Then you'll see, that it is not the spoon that bends, it is only yourself. #thematrix #theone #advancedphysics

Week 31: January 12-16 (2k15)

So on January 13 our lesson in Physics was all about  Circuit Protector, fuse, and circuit breaker.

Circuit Protector- to protect circuitry at home (Accidents at home are caused by “faulty wiring.”)

Fuse- protects the circuit by stopping the whole circuitry through melting.

Week 24-29: November 10- December 19 (2k14)

When I reviewed my notebook in Physics, I had not seen any notes on these dates. Maybe this was the time when the coaches and contestants were preparing for the Science Quest.

Week 22: October 27-29 (2k14)

On October 27, we dealt with the topic Electromagnetism. Electromagnetism was coined from the word “electricity” and “magnetism.”  The word electricity also comes from the greek word “elektron” which mean “amber.”

 The two types of charges (According to Benjamin Franklin):

         1. positive

         2. negative

Note: Unlike charges attract, like charges repel.

Law of Conservation of electric charge.

The net amount of electric charge produced in any process is zero.

Coulomb’s Law

Charles Coulomb (1736-1806) investigated electric forces in the 1780s using a torsion balance much like used by Cavendish for his studies of the gravitational force

Fe=kQ1Q2/r^2

---

The discussion of Coulomb’s Law was then continued on October 29. In Coulomb’s Law, electric force increases if unlike charges are near.

In the equation F=Keq1q2/r^2, Ke is equal to 9x10^9 N.m^2/c^2 or ke= 1/4πE0 where E0=8.85x10^-12.

Charging means gaining or losing electrons.

Charging can be through:

            -Friction/Rubbing:

             Net charge= 0 = conserved

            -Induction

            -Conduction

Week 20-21: October 13-24 (2k14)

We had no classes on October 13-17 due to busy schedule and also on October 20-24 because it was our semestral break.

Week 15-19: September 8 - October 10 (2k14)

Since I don't have new notes and I ran out of leaves in my notebook... If my memory fails me not, we only had some exercises this week about mass defect, binding energy and computing the mass defect of nuclear fission which we can get it from this equation: △m=Mreactants - Mproducts.

Week 14: September 1-5 (2k14)

In this week, we talked about Radiation Applications. First we can apply radiation to food and agriculture. Example when exporting goods, killing microorganisms and sterilizing male insects. Second, in diagnosis and therapy. For example, radioisotopic tracing can trace cancerous cells. Chemotherapy can somewhat help cure cancer. RIA Technique can be applied to hepatitis A virus.

Third, in radioactive dating. For example, in carbon-dating, we can use isotope carbon 14 to identify age of living organisms. Another example is uranium-dating. Uranium 238 and 235, Thorium and Potassium can help identify the age of non-living things.

Another topic we discussed this week is mass defect and binding energy.

To find mass defect, you need to subtract atomic mass from the nuclear mass. To do this. first, you need to find the mass of the element's protons and neutrons. Here's the constant value:

Mp+= 1.0073 amu Mn =  1.0087 amu

For instance you're finding the mass defect of Lithium which has an atomic mass of 6.9380 and atomic number 3. So... Mp+= 1.0073 amu * 3 = 3.0919 amu Mn = 1.0087 amu * 3 = 3.0961 amu

Adding both products will result to nuclear mass. So the nuclear mass is 6.9380 amu.

Now start subtracting...(△m= mass defect) △m = nuclear mass-atomic mass △m = 6.9380 amu - 6.0480 amu △m = 0.8900 amu

Now to find the binding energy, here's the formula: BE= △mc^2 BE of lithium=( 0.8900 amu ) (931 MeV/amu) [Here, we need to convert amu to MeV (Mega Electrovolts)]

So the answer is:

BE= 828.59 MeV

Week 13: August 25-29 (2k14)

We talked about Radioactive Decay this week.

84 or more protons are radioactive.

Transmutations - radioactive decay.

Half-Life = original amount/2^n

(We only had our class on Aug. 26)

Week 12: August 18-22 (2k14)

I think we didn't have our class this week because I didn't have notes.

Week 11: August 11-15 (2k14)

I think we didn't have our class this week because I didn't have notes.

Week 9: July 28- August 1 (2k14)

Here's what I learned:

Holography - is a technique to reproduce image interference effect.

The angular magnification of a magnifying glass is M=Theta prime 1/Theta.

(We only had our class on July 30-31 in this week.)

Week 8: July 21-25 (2k14)

The shorter the wavelength the higher the frequency.

Interference - overlapping of wavelength

Amplitude - height

Frequency - number of cycles per second(Hertz)

Diffraction - spreading out of light waves

Light is a wave and a particle where photons are the particles of light and carrier of energy.

E=hf (Light Constant) where h= 6.626*10^-34 J*s

Diffraction is the bending of waves around obstacles or the edges of an opening.

Dispersion is the scattering of light.

Dispersion is the spreading of light into full spectrum.

Light is a transverse wave, an electromagnetic wave.

Phenomena: Reflection, Refraction, Dispersion
