What is the equivalent capcitance of this circuit! -- Figured it out. I have a Physics final exam in 2 hours and I'm re-reviewing things... This problem DOESN'T make any sense! 17. If C1 = 2 F, C2 = 3 F, C3 = 5 F, C4 = 6 F, the equivalent capacitance of the circuit is: A. 8.5 F is supposed...

I have just a few more questions regarding index of refractions and reflections... 8. A fly is 10 cm above the surface of a pond. How high above the water does the fly appear to a fish directly below (nair = 1, nwater = 1.333)? (A) 10 cm (B) 7.5 cm (C) 13.3 cm (D) 12.5 cm (E) fish cannot see...

Anybody still willing to help me out? :(

Ohh I get it. So n_2sin(30°) = n_3sin(60°)\\n_1 = n_2 For n2, θ2 is small, so n2 must be larger. For n3, θ3 is large, so n3 must be smaller. Thanks! I have just a few more questions regarding index of refractions and reflections... 8. A fly is 10 cm above the surface of a...

You still there? :(

Or I should say... The index of refraction measures the bending of a ray of light when passing from 1 medium to another. The thicker the medium - the greater the "n", the slower the light passes, the smaller the angle (more towards the normal) The thinner the medium - the smaller the "n", the...

Hmm...Well I had to google this but, according to what found. Light (coming out of material n2) bends AWAY from the normal A LOT when it gets to medium/material n3. This means that there is not as much density in medium n3 to slow light down as there is in materials n1 and n2 (which are...

7. The figure shows the path of a portion of a ray of light as it passes through three different materials. What can be concluded concerning the refractive indices of these three materials. (A) n1 < n2 < n3 (B) n1 > n2 > n3 (C) n3 < n1 < n2 (D) n2 = n1 > n3 (E) n1 = n2 < n3 The...

Oh goodness... So what should M equal?

The answer has to be B then... Ok well since I know I got those top 3 questions wrong...I wouldn't mind moving on to the other questions I wouldn't mind you guys checking for me... I chose D…but I don't think it's right… I did this: Given: R = 10 cm f = -R/2 (since it's convex) = -10/2 = -5...

I forgot how to because I did this back in high school and my teacher (in college) just gave us a simple chart to follow and didn't emphasize the fact that we had to draw a ray diagram. :(

So the answer IS E. real (image on front), enlarged, inverted.

What do you mean?

Ok but my answer is still wrong though... The answer for 3 would have to be D.
