    Periscope reflection, but it seems backwards

    Then I would think B would be the image from 1, but then there is no image from 2... I mean D is perpendicular, but it is further away then the distance from the object to the original mirror

    Periscope reflection, but it seems backwards

    Then I thought the answer might be C and G, but that's also incorrect, I'm just not sure what to do!

    Periscope reflection, but it seems backwards

    This is the question and the answer choices. I thought it would be mirror one creates E and mirror 2 creates F, but It's not... help?

    Bernoulli's Principle with a Venturi Tube, find flow rate

    I understand the equation ρgy1+ (1/2)v1^2 + P1 =ρgy2+ (1/2)v2^2 + P2 but I do not understand how to apply it to this

    Bernoulli's Principle with a Venturi Tube, find flow rate

    So that's the question and I'm stuck on Part b. I don't even know how to approach it. I know A1= 3A2 but I don't know A1 and I need V2 and I don't know V1 or A2. I'm just confused as to how to do this. Please help!

    Relating moment of Inertia and pendulum oscillation

    so am I solving for α in that equation and that's identical to the period?

    Relating moment of Inertia and pendulum oscillation

    I took a picture of the question to help. I know that the moment of inertia for a rod (at one end, not the center) is: 1/3ML^2 And I know that the period of oscillation is: T=2∏√(L/g) But I don't know how to relate them... I tried doing Torque=Iα=Fdcosθ and solve in terms of...
