Oscilloscope time base problem. you are asked to display a 1 khz sine wave signal on the screen. since the period t is related to the frequency f by the formula t = 1 / f, the period of this wave is 1/(103/s)=1ms, so a reasonable setting for the "time/div" dial is 1 ms/div. but suppose you select an inappropriate setting for the time/div dial by mistake. what would you see if you set the dial on 1 μs/div? 100 ms/div?

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

answer; the correct answer is technician a; ///100%good luck

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
