1. a battery can be modeled as a source of emf in series with both a resistance of 10 ω and an inductive reactance of 5 ω. for a maximum power delivered to the load, the load should have a resistance of rl = 10 ω, an inductive reactance of zero, and a capacitive reactance of 5 ω. with this load, is the circuit in resonance?
a)yes
b)no
c)it depends on the voltage provided by the battery.
2. with this load, what fraction of the average power put out by the source of emf is delivered to the load?
a)0
b)0.2
c)0.5
d)0.7

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
