Quick question about pressure radiation for reflection

AI Thread Summary
The discussion centers on the calculation of pressure radiation for reflection, specifically in terms of force and area. The equation for radiation pressure upon reflection is given as pradiation(reflection) = 2I/c, where I is intensity and c is the speed of light. The user attempts to express this as pradiation(reflection) = 2F/A, questioning the correctness of their solution. However, it is noted that the pressure should simply be defined as p = F/A without the factor of 2 in the second equation. The conversation emphasizes the distinction between the two equations and clarifies the correct formulation of radiation pressure.

Homework Statement


write pressure radiation for reflection in terms of force and area


Homework Equations


pradiation(reflection)=2I/c
p=F/A


The Attempt at a Solution


pradiationreflection=2F/A

is that correct? (im fairly certain I've solved this correctly but i just wanted to check)

radiation pressure , in the case of reflection is \frac{2I}{c}, but the pressure is just force per unit area. so you should not have the factor of 2 in the second equation
 

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'

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...
