At what rate does it emit energy by radiation?

AI Thread Summary
To calculate the rate at which a red-hot horseshoe emits energy by radiation, one must apply the principles of blackbody radiation. The horseshoe has a surface area of 60 cm² and is heated to 930°C. Understanding Kirchhoff's law of thermal radiation is essential for this calculation. The original poster expresses confusion about blackbody radiation and seeks assistance. The discussion highlights the need for clarity on thermal radiation concepts to solve the problem effectively.

Do you know of blackbody radiation?
 


No I do not.
 


Can anyone help me?
 


I did not get it in time, thanks anyway.
 

Thread 'Errors and significant figures'

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 'A cylinder connected to a hanging mass'

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...
