Dear experts.Which example file in Geant4 can I use to find the particles and energies produced in the target?

First I assumed the question asks about max e.m.f so I just used ratio: output voltage = (2500 / 1100) x 12.7 = 28.9 V, but the answer is wrong. Then I tried to use the ratio of the whole formula: $$\frac{\varepsilon_{1}}{\varepsilon_{2}}=\frac{NBA \omega_{1} \sin(\omega_{1}t)}{NBA \omega_{2}...

I want to ask about part c (iii). This is what I did: max e.m.f produced = NBAω = 32 x 0.074 x 4.8 x 10-2 x 2.4 x 10-2 x 2π x 9 = 0.15 V But the answer is 0.077 V so my answer is off by factor of two. Is my mistake related to "emf produced across the side of AC of the coil"? Thanks

Hello. I am wondering; which solid at room temperature elements produce oxygen gas when put into a solution of sodium hydroxide? Thanks

Hi, I was trying to read about the current produced by a dynamo in my physics books but I can't find any reference. I have a rotor rotating at a certain speed, air flow and with a certain inertia, but how can i find the power produced and related current and tension?

The answer is that there would only be a 250 bp fragment, and it would be brighter. I think that there would just more fragments of all sizes, as more DNA is degraded. I don't understand why there wouldn't be fragments of larger sizes. Thanks!

Hello, I have used an edge current of 10 A through a 0,45 cm (lenght) wire inside an air sphere. The thing is that, according with Ampere law, the magnetic field (B) produced at a 1 mm of distance from the wire shall be 0,002 T, and I am obtaining much higher values in this simulation (around...

i found current to be 2/5 A. then 2/5A multipled by 6s = 2.4C. and since one joule per coulomb is equal to the unit of p.d, i get 2.4J. I don't get 4.8J(supposed answer)

The solution for a) is 2H2O+2e- → H2 +2OH-, and the solution for b) is O2, because the half reaction at the anode is 2H2O→O2 +4H+ + 4e-. I don't understand why the electrolysis does not involve Na2SO4 being reduced or oxidized, and only considers water. Thanks.

A thought experiment: A electron is moving in a straight line at velocity v. It instantly stops dead. It doesn't move another femtometer. Obviously its magnetic field collapses and produces light. What is the waveform of the light produced? Is it something like this...

Table: To solve, using the conservation of energy: E0=(m(deutron)+m(16O)-m(17O)-m(p))c^2 so: E0=(2.014+15.994-16.999-1.008)931.5=0.93 MeV. so using the conservation of energy: 14.95+0.93=16.62+0+E' E'=- 0.74 MeV But the energy sign has become negative. I also calculated for the first excited...

I was wondering about EM waves produced by linearly accelerating charges, as opposed to oscillating charges. With oscillating charges, the frequency of the wave depends on the frequency of the oscillation of the charge. But what determines the frequency of the wave produced by a linearly...

Hello, everyone. Does anyone know how much steam is produced by an electric arc furnace in a set amount of time? I have not been able to find any information on this despite how much water is no doubt used to cool the electric arc furnace. Can anyone help?

My Attempt So Far: 1. Write down all information: Q=10m³ /min h=75m 2. Change 10m³ /min to m³ /s 10m³ /min × min/60s =1/6 m³ /s 3. Change Volumetric Flow Rate to Mass Flow Rate ṁ=ρQ ṁ=1000kg/m³ × 1/6 m³ /s ṁ=166.67 kg/s 4. Apply Potential Gravitational energy but replacing the Mass with...

I'm currently researching if I could implement some wave energy into my small scale hypothetical project. I've identified some commercial models, namely Seabased and SINNPower, and I assumed that they would have approximate values of power output given wave period, height (among many other...

So I worked out the first part and obtained ##E_1 = 478.8MeV##, ##E_2 = 459.4MeV## and ##p = 0.49 MeV/c## but I can't quite wrap my head around the second part. Normally, I'd use the equation for s but I'm confused since I don't know the angle between the gamma rays.

So, a static charge at rest produces an electric field, but no magnetic field. A charge moving with constant velocity produces both electric and magnetic fields. Why is it that accelerating charges are the source of all electromagnetic radiation? How would one go about showing this using...

To begin, I am not sure whether or not this is the correct location for this post since I am a complete greenhorn to this forum (just joined today!). I ask how much heat is produced by radioactive waste because I was wondering if it was viable to reuse all the tons of stored radioactive waste...

I have looked everywhere, but most of the sources say water is not produced (which is not true), and some sources, such as my biology textbook, simply say it is produced. I know for every 6CO2 put into the Calvin cycle, 6 oxygen atoms are put into 2*G3P. Where do the other 6 leave the Calvin...

Hi So I am busy studying rotational motion and there's an example in the book where they explain that when a car brakes the force of friction acts as a torque force which explains why a car lifts up at the back when braking. Because the car does no rotational motion they say the net torque is...

So the recent neutron star merger event showed that most of the heavy elements (gold, platinum, uranium, etc.) are produced in kilonovas. But with neutron star mergers so rare, there can't be that many kilonovas. Prior to this I always used to think they were mostly produced in supernovas. The...

If I compress a spring beyond its most relaxed point it will have more energy and thus by General Relativity produce a stronger gravitational field than the uncompressed spring will. But suppose instead I pull in the opposite direction and stretch the spring beyond its most relaxed point it is...

My question is simply 'are all notes produced in a guitar produced by first harmonics?', but I will clarify what made me ask this question. Now, if you have a wave driver you can make several harmonics in a string by increasing the frequency of the machine. In a guitar string, however, it does...

As I understand it, carbon composites are some combo of polymers and resins, which are derived from oil(black goo from the ground) as the main raw resource. However, as this is carbon, couldn't such materials be produced also from other sources, like corpses, plants, etc? I mean, carbon is...
