Kirchhoff's loop rule says that the sum of the potential changes around a loop must equal zero. therefore, if the input voltage at some moment is 10v, then the voltage drop across the diode plus the voltage drop across the resistor must equal 10v. in general, this gives the equation ir+vd=vin, where i is the current through the diode and resistor, r is the resistance of the resistor, vd is the voltage drop across the diode, and vin is the potential difference of the source. (note that the current through the diode is the same as the current through the resistor because the circuit shown has only one loop.) if you plug in the current-voltage relationship for a diode given in the problem introduction, you will get an equation for vd in terms of r. unfortuately, this is a transcendental equation, which must be solved numerically. for parts b - d, assume that the input voltage is 10 v, the resistance is 1.000kω, and the potential difference across the diode is only 0.3561v. part b what is the current i that flows through the diode? express your answer in amperes to three significant figure. i i i = nothing a

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
