Does Ap Physics have anything to do with probablity?

1 answer:

5 0

So I'm a junior. I am currently taking AP Calc BC and AP Physics B.

As of now, I'm not sure if I should take AP Probability and Statistics or Differential Equations/Calc III next year. Also, I'm debating between taking AP Physics C or AP Chemistry.

Which ones do you think would look better on a transcript? I heard that Diffeq/CalcIII is harder than AP ProbStat, but ProbStat is an AP course which will be weighted heavier. Also, should I take Physics C since i've taken Physics B this year already?

Determine the equivalent capacitance between a and b for the group of capacitors in the drawing.

iragen [17]

Answer:

There are different of arrangements for the capacitors to work inside a given system, as there are two different form of arrangements for the capacitors to be in, which are:

The parallel connections of capacitor,
The series connections of capacitor.

Explanation:

The parallel connection of capacitor is comprised of capacitors having the unequal amount of current, ΔI. And has a same potential difference across the number of capacitors. And the equivalent amount of capacitance,ΔC is calculated by the following equation:

ΔC(eq)=C₁ + C₂ + C₃ + C₄ + C(n),

For the series form of arrangements of the capacitors we have the different form of equation which can be explained by the total number of capacitors that are connected in series in combination as they are provided by the equal amount of current,ΔI across it, while the voltage or total amount of potential difference, Δv provided to the system is more different for each of the capacitor. And the equivalent amount of capacitance, ΔC(equivalent) can be determined by the following equation:

1/C(eq)=1/C₁+1/C₂+1/C₃+1/C(n).

A high-speed K0 meson is traveling at β = 0.90 when it decays into a π + and a π − meson. What are the greatest and least speeds

san4es73 [151]

Answer:

greatest speed=0.99c

least speed=0.283c

Explanation:

To solve this problem, we have to go to frame of center of mass.

Total available energy fo π + and π - mesons will be difference in their rest energy:

$E_{0,K_{0} }-2E_{0,\pi } =497Mev-2*139.5Mev\\$

=218 Mev

now we have to assume that both meson have same kinetic energy so each will have K=109 Mev from following equation for kinetic energy we have,

K=(γ-1) $E_{0,\pi }$

$K=E_{0,\pi}(\frac{1}{\sqrt{1-\beta ^{2} } } -1)\\\frac{1}\sqrt{1-\beta ^{2} }}=\frac{K}{E_{0,\pi}}+1\\ {1-\beta ^{2}=\frac{1}{(\frac{K}{E_{0,\pi}}+1)^2}}\\\beta ^{2}=1-\frac{1}{(\frac{K}{E_{0,\pi}}+1)^2}}\\\beta = +-\sqrt{\frac{1}{(\frac{K}{E_{0,\pi}}+1)^2}}\\\\\\beta =+-\sqrt{1-\frac{1}{(\frac{109Mev}{139.5Mev+1)^2}}$

$u'=+-0.283c$

note +-=±

To find speed least and greatest speed of meson we would use relativistic velocity addition equations:

$u=\frac{u'+v}{1+\frac{v}{c^{2} } } u'\\u_{max} =\frac{u'_{+} +v_{} }{1+\frac{v}{c^{2} } } u'_{+} \\u_{max} =\frac{0.828c +0.9c }{1+\frac{0.9c}{c^{2} } } 0.828\\ u_{max} =0.99c\\u_{min} =\frac{u'_{-} +v_{} }{1+\frac{v}{c^{2} } } u'_{-}\\u_{min} =\frac{-0.828c +0.9c }{1+\frac{0.9c}{c^{2} } } -0.828c\\u_{min} =0.283c$

When placed in water does a pencil bend towards the normal or away from the normal?

Anarel [89]

Answer:

ni sin theta i = nr sin theta r where theta i is the angle of incidence and theta r the angle of refraction

For nr greater than ni (air to water) theta r must be smaller and the image would be bent towards the normal

Why do protons repel protons but attract electrons ??

erma4kov [3.2K]

Ever heard of, "<em /><em>Opposites attract"</em>?

Protons attract the opposite --> electrons.

Protons --> +
Electrons --> -

+ cannot attract +, so they repel.
