A small, 250-μm-diameter bead is fired horizontally into 20∘C olive oil (η = 8.4×10−2Pa⋅s) at a speed of 0.29 m/s. Its stopping distance in the olive oil is 11 μm. What is the mass of the bead in μg? I'm not sure which equation I'm supposed to be using, or how to come up with one.

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

What is the angular momentum of the bar about the axle?

Use the profile illustrated for problem (1). assume that the layer of silty sand fill (sm) is placed over the entire site. estimate the thickness of the fill (h - in feet) that will cause the effective vertical stress at the center of the clay layer to increase by 517.5 pounds per square foot.
