A simple Potter's Wheel is 50 cm in diameter. When it turns once, a point on its rim moves a little more than 150 cm. A pot 20 cm in diameter is
centered on the Wheel. When the Wheel turns once, so does the pot. As
the pot turns once, a point on its rim moves a little more than 60 cm.
Explain how the mechanical advantage of the wheel and axle make it
easier to shape the pot.

Suppose you increase your walking speed from 7 m/s to 13 m/s in a period of 2 s. what is your acceleration?

Wavelength of 125 meters is moving at a speed of 10 m/s. what is it's frequency?

Aspecified volume of space contains an electric field for which the magnitude is given by e=e0cos(ωt). suppose that e0 = 20 v/m and ω = 1.0 × 107 s−1. part a what is the maximum displacement current through a 0.80 m2 cross-sectional area of this volume? express your answer with the appropriate units. idisp,max i d i s p , m a x = nothing nothing request answer part b how would this area have to be oriented relative to the electric field to get this maximum displacement current?
