AI Thread Summary
The discussion centers on a 150MHz sinusoidal plane wave propagating in air at a 30-degree angle to the +x-axis in the x-y plane, with an E-field magnitude of 2 V/m. The main concern is how to accurately represent the orientation of the wave in a diagram. The contributor is uncertain about the correct depiction of the angle and seeks clarification on whether their current drawing aligns with standard conventions. They suggest that the angle should be measured counterclockwise from the +x-axis, indicating a preference for representing it as 30 degrees north of east. The conversation highlights the importance of proper orientation in visualizing wave propagation.

Homework Statement



A 150MHz sinusoidal plane wave propagates in air at 30 degrees with respect to the +x-axis in the x-y plane. The E-Field is polarized parallel to the plane of incidence and has a magnitude of 2 V/m.

The Attempt at a Solution



My only question is about the orientation. I can't figure out how to draw the picture! Click on the image below to see what I have now. Is one of these orientations correct?

there isn't anything given in the question to indicate that.

but because of the normal way we choose to represent the angles (CCW starting from the +x axis) I would choose to fo 30 degrees N of E
 

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...
