- Figure CQ20.7 shows a slidewire generator with motional cmf 0 when the wire at A slides across the top and bottom rails at constant velocity v0. (a) When the wire reaches B so that the area enclosed by the circuit is doubled, determine the ratio of the new cmf to the original cmf, /0. (b) If the wire's speed is doubled so that v = 2v0 determine the ratio /0. Figure CQ20.7arrow_forwardB. Solve the following circuits (fill in the missing values).

First, a very short laser pulse vaporizes and ionizes a bacterial sample. The positive ions are accelerated, in vacuum, through a -15 kV potential difference, and then they travel at constant speed through a 1.5-m-long drift tube to a detector that records their arrival times. An ion's time of flight depends on its mass, so a record of the arrival times can be used to determine the masses of the biomolecules that were released from the bacteria. Each type of bacteria has a unique set of proteins with different masses, so the mass spectrum is a fingerprint for identifying bacteria. Part A What is the mass in kDa of an ionized protein that is detected 51 us after the laser pulse? You can assume that the protein is singly ionized (g = +e) which is mostly true in practice. You can also neglect the time needed to accelerate through the potential difference because it is very small…arrow_forward
