Two technicians are discussing engine mechanical testing. technician a states that a cylinder power balance test should be used to identify a cylinder with low compression. technician b states that a cylinder power balance test is used to identify a specific cylinder that is misfiring. which technician is correct?

Spend time observing or thinking about events that involve matter and energy. which events can you explain? which events can’t you explain?

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.

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.
