A laboratory hydro test installation has a vertical drop of 10 feet. The system produces a total of 150W. You are testing water and ethanol to determine which liquid will have a higher efficiency. When you test water, you are able to achieve 1.9 gal/s of flow, while when you test ethanol, you are able to achieve 2.3 gal/s of flow. Which liquid has the higher efficiency

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.

Figure 9 on page 362 shows various motions of balls. the curved path followed by the yellow ball in b in picture b is result of a) inertia b) centripetal motion c) gravity and horizontal velocity d) linear motion

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?
