What is the science behind 3D glasses? I need at least a paragraph! Thanks!!!

Answers

Answer 1

Answer: The projectors project perpendicularly polarized light with respect to each other and the screen maintains this polarisation. All that is needed are simple 3D glasses with polarised frames that make sure that the image made from the right camera coming from the right projector goes into our right eye and the light from the left projector goes into the left eye and our brain puts it all together to give us stereoscopic 3D vision of a 2D screen

What is the mass of 0.7891 mol of (fe2o3)?

Answers

Molar mass F₂O₃ = 159.69 g/mol

1 mole ------------------ 159.69 g
0.7891 moles ---------- ? g

mass = 0.7891 x 159.69 / 1

= 126.01 g

The slope of a speed time indicates

Answers

The slope of a peed versus time graph indicates acceleration. You can prove this by the fact that slope is Δy/Δx and the units for y are m/s and for x are s which means that the slope has the units (m/s)/s which are the same units used for acceleration.
I hope this helps. Let me know in the comments if anything is unclear.
