the circuit shown below is made using identical bulbs and an ideal battery.

The circuit shown below is made using identical bu

a)Which of the following statements is correct? Explain your reasoning for the choices you have made.

Bulb D is brighter than bulb F.

Bulb D is dimmer than bulb F.

Bulbs D and F have the same brightness.

There is not enough information given to compare the brightness of two bulbs.

 

b)Bulb D in the circuit above is then removed from its socket. (What happens when a bulb is removed? Study the description of a bulb's construction on page 2 of the Electric Circuits I: Current lab if you are unsure.) When bulb D is removed from its socket

the brightness of bulb F would:

- Increase

- Decrease

- Stay the same

- Not enough information

The circuit below contains an ideal battery, a resistor, and two identical bulbs. 

The absolute value of the voltage across the bulb B is,

(a) Greater than the voltage across the bulb A.

(b) Less than the voltage across the bulb A.

(c) Equal to the voltage across the bulb A.

(d) Not enough information provided. 

Please please please help, I have a huge physicsproject duebut am a complete loss at what type of circuitsthese are
1) A circuit consists of three identical lightbulbsconnectedto a battery, but their wiring scheme is unknown. Whenbulb C isunscrewed, all the lights turn off. When bulb A isunscrewed, theother two stay on: bulb C becomes dimmer and bulb Bbecomesbrighter.
2) A circuit consists of three identical lightbulbsconnectedto a battery, but their wiring scheme is unknown. Whenbulb A isunscrewed, this causes bulb B to turn off but bulb C'sintensitydoes not change.
I understand the concept of complex circuits but cannotfirureout which bulbs are in series, parallel, and where they areplaced.Karma points will be awarded

1) We shine light onto a metal surface. We observe that someelectrons are emitted from the metal surface if the frequency ofthe light exceeds some critical frequency f0 = F/h, where F = thework function for this metal. What happens if the light's frequencyf is less than f0? ( Ignore reflections off the metalsurface.)

a) The electrons leave the metal but are attracted back toit.
b) The photons get absorbed by the electrons but the electrons stayinside the metal.
c) Whether or not any electrons leave the metal depends on theintensity of the light.

2) Now we shine light of a frequency f > f0 onto the metalsurface and in addition apply a voltage V between the metal and theelectrode. What happens if V is a tiny bit larger than (1/e) (hf -F )?

a) Some electrons barely make it to the other electrode.
b) All electrons turn around before reaching the otherelectrode.
c) No electrons escape the metal.

3) Consider a photon with a frequency of 1 GHz. What is the ratioof its wavelength ?? to the de Broglie wavelength ?e of an electronwith the same kinetic energy? (Note: It is standard to use thesubscript '?' to stand for photons.)

??/?e =
a) 2.01e-006
b) 1.21e-003
c) 1
d) 8.24e+002
e) 4.97e+005

4) The mass of the electron is 0.511 Mev/c2. A muon µ can beregarded as an electron with mass mµ = 105.7 MeV/c2.
Let the muon have kinetic energy E.
Define ?µ to be the de Broglie wavelength of the muon with energyE.
Define ?e to be the de Broglie wavelength of an electron with thesame energy E.
Calculate the ratio of wavelengths ?µ/?e.

?µ/?e =

a)0.005
b)0.070
c)1.
d)14.382
e)cannot be determined from the information given
