Oscilloscope time base problem. you are asked to display a 1 khzsine wave signal on the screen. since the period t is related tothe frequency f by the formula t = 1 / f, the period of this waveis 1/(103/s)=1ms, so a reasonable setting for the"time/div" dial is 1 ms/div. but suppose you select aninappropriate setting for the time/div dial by mistake. what wouldyou see if you set the dial on 1 μ s/div? 100 ms/div? a. asine wave shifted to the left on 1 μ s/div and to the right on100 ms/divb. a(nearly) horizontal line on 1 μ s/div andmany (nearly) vertical lines of 100 ms/divc. nothing on either (no trigger)d. anormal sine wave in both casese. none of these

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?

Amoving electron has kinetic energy k1. after a net amount of work w has been done on it, the electron is moving one-quarter as fast in the opposite direction. (a) find w in terms of k1. (b) does your answer depend on the final direction of the electron's motion?
