AI Thread Summary
The discussion revolves around calculating the energy equivalent of a girl weighing 45.45 kg using Einstein's equation E=mc^2. The initial calculation yielded an energy value of 4.9 x 10^18 J, which was later corrected to 4.09 x 10^18 J due to a significant error in the exponent. Participants questioned the purpose of the calculation, humorously suggesting it might relate to nuclear fission. The conversation highlights the importance of precision in scientific calculations. Overall, the correct energy equivalent is confirmed to be 4.09 x 10^18 J.

If some girl weighs 100 pounds or 45.45 kg

E=mc^2

Energy = (45.45) x (3 x 10^8)^2

My answer was 4.9 x 10^1^8 J of E. But it's been a while and I'm not confident. Is that wrong?


thanks

That should be right. Why do you need to know? Are you planning to put the girl through nulcear fission...?
 
What are you doing? 5^9?

I'll assume you made a mistake, the answer is 4.0905 * 10^{18}.
 
Ok thanks, 4.9 x 10^1^8 J of E.
 
NO! 4.09 x 10^{18}, that zero is a huge difference.
 
Ok, thanks for your forbearance candyman.

Thanks a million.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
