Homework Statement Derive the scaling law for static buoyancy force of a solid sphere in a liquid with a density of γ. Assume the sphere is made of a material with a density of γs (γs< γ). Homework Equations The Attempt at a Solution I calculated the the buoyancy force of the...

A silicon wafer is 500 μm thick. The front surface is {100}. A mask consists of a rectangular window of unknown size. The sides of the window are parallel to <110>. After through-wafer etch, a window (50 μm by 80 μm) is formed on the other side of the wafer. Find the size of the original mask...

Homework Statement For the following circuit, sketch v2/v1 as a function of R4, if R1=R2=R3=R5=R. Also explain the behaviour of the circuit when R4=R/2. Homework Equations The Attempt at a Solution After solving the circuit, i came up with v2/v1=2R4/(2R4-R). Now, if R4=R/2 ...

Homework Statement The op amp circuit shown bellow is intended to provide any gain between -10 (for k=0) and +10 (for k=1) by adjusting the potentiometer. Let R1 and R2 have the scaled values, show that.. V2/V1= {r1/(r1+10k)} [-11/{1+(10kr1/r1+10k)}] + [r2/r2+10(1-k)] [1+...
