Energy released Definition and 75 Threads

Atomic bombs are really powerful and destructive devices. I understand that during a fission reaction, the parent isotope splits in 2 lower mass isotopes with high kinetic energies due to the binding energy that were released. But I don't understand how this becomes into the destructive effects...

Using the equation Force = Pressure x Area. How much energy would be released from an iron tube 48” long with an inside diameter of 2.1” and outside diameter of 3”. Wall thickness would be .9”. With 8500psi inside. Maybe I calculated it wrong but I got 1.1 million pounds of force released. Once...

I have been learning particle physics lately but it's been mostly from a theoretical perspective and not a mathematical one so I have yet to come across any such math but my curiosity is peaked. From what I understand it, this is the process: n \rightarrow p + W^{-} Followed by...

Why do some chemical reactions release energy, while other chemical reactions absorb energy?

One of the possible decay modes of the neutral kaon is K-> pion + pion The rest energies of the K0 and pion are 498 MeV and 135 MeV, respectively. The kaon is initially at rest when it decays. a) How much energy is released in the decay? b) What are the momentum and relative direction of...

Homework Statement a mass of 3.33x10^-28kg of uranium is converted into energy during nuclear fission (exploding) according to einstien's formula E=mc^2 where energy is measured in joules (J), m is measured in kg and c = 3000000000m/s is the speed of light Homework Equations show...

Homework Statement The first step of the CNO cycle is p \rightarrow C_{6}^{12} \rightarrow N_{7}^{14} + \gamma Estimate the energy of the CNO cycle, state any assumptions. Homework Equations - The Attempt at a Solution I was looking at mass difference, (1.00728u...

Homework Statement A 6.91x106 kg spherical spaceship in deep space explodes into two pieces, one 4.77 times the mass of the other. NOTE: the velocity needs magnitude and direction (given by the sign). a) Suppose the ship is initially at rest, and after the explosion the smaller piece is...

Is there a way the quantify the energy 'released' by a hurricane? Does the energy have a source so to speak?

Homework Statement Two deuterium nuclei (deuterium= 2.014102u) combine thru fusion to form a tritium nucleus (mass 3.016050u) and a proton. 2. Attempt at solution Two parts to this problem: a) Calculate the energy released in one fusion reaction (in MeV). So for this I went [(initial...

Hi all. I'm new to this forum, but I checked the FAQs and I think I'm in the right place to ask this: Is there just one type of energy that is released during a nuclear explosion? Please let me explain. I'm in a very complicated argument with someone, and the argument has come to this...

Why more energy is released in fusion than fission?

[SOLVED] Radioactive decay. Is energy released? OPINION PLEASE! This is my last question in my last Physics exam! YES! I'M ALMOST DONE! :smile: I would just like your opinion on this question... My answer is Yes... But sometimes I think it should be NO because of the question's option for a No...

I was working at the energy released through the triplealpha process, and came to a slight problem. I worked out for Helium first, using: (2 x 1.007825u) + (2 x 1.008665u) - 4.002602u = 0.030378u which when x3 and converted gives ~84.9MeV. Doing the same for carbon, but using 12.011u...

Homework Statement What is the energy released as water changes temperature from 20C to -10C? Homework Equations mct+lfm+mct The Attempt at a Solution My physics exam is day after tomorrow, however, I have no clue about this question. I was away for a week during these lessons. Can...

Homework Statement A typical fission reaction is U(92,235) → Zr(40,98) + Te(52,135) + 2 n The numbers in parentheses are (Z,A) for each isotope; n stands for a neutron. The atomic masses of the isotopes are: U(92,235) = 235.043923 u; Zr(40,98) = 97.912746 u; Te(52,135) = 134.916450 u; n =...

hi guys, iam kinda stuck on 2 problems. here is what it is : The nuclear fission reaction of uranium-235 with one neutron produces germanium-81, 5 neutrons and another element, what element is that? what's the atomic number andatmoic mass,?give the equation. 2. how much energy is...

I have just started AP Chemistry this year as a junior at my high school despite all peer protests against it. And I admit so far the course has lived up to it's reputation of being very difficult. I was rather ecstatic to come across this site where I may obtain the help I /know/ I will need...

Homework Statement Consider the following problem: 1) Calculate the energy released in the fission reaction, Uranium(235,92) + neutron--->[Uranium(235,92)]*--->Neodymium(143,60) + Zirconium(90,40)+ 3 neutrons + 8 electrons +8 antineutrino Homework Equations The Attempt at a...

A projectile of mass 20.6 kg is fired at an angle of 59.0^\circ above the horizontal and with a speed of 76.0 m/s. At the highest point of its trajectory the projectile explodes into two fragments with equal mass, one of which falls vertically with zero initial speed. You can ignore air...

I can't quite figure this out... but given this sceneraio: Precipitation and energy can be thought of as closely related quaniities in a thunderstorm. That is, when rain forms via condensation, the atmosphere warms from the latent heat released. The amount of heat energy must be proportional to...

for the following question: dynamite liberates about 5.4*10^6 J/kg when it explodes. What fraction of its total energy content is this? my problem: the total energy formula=(gamma)mc^2 but the gamma factor has v, but the question doesn't have v... any suggestions?

Can someone help me on this problem? Here's my work :) Calculate the energy released in the fission reaction: n + 235/92U-> Sr-88 + Xe-136 + 12n Use appendix D, assume the initial KE of the neutron is very small It can be seen that when the compound nucleus splits, it breaks into...

Hi everyone, I've been trying to do this question here but I'm stuck on the last part: A 23.0 kg body is moving with a speed of 25.0 m/s in the direction of the positive x-axis when, owing to an internal explosion, it breaks into three parts. One part, which has a mass of 5.50 kg, moves away...
