1. My flight was overbooked. (overbooked = there were too many passengers and not enough seats) 2. My flight was delayed/canceled. 3. My luggage was lost. 4. I was jet-lagged. (= I felt tired because of the time zone difference between my origin and destination) 5. My hotel was in a seedy area. (seedy = possibly unsafe) 6. I was mugged. (= I was robbed on the street) 7. The weather was miserable. 8. I got the runs. (= diarrhea) 9. The place was a tourist trap. (= made only for tourists; not authentic) 10. I couldn't wait to get back home.
An unknown frequency source signal generator is
connected to y plates of C.R.O . Time base signal is connected to x plates internally
connected . We get a sinusoidal wave on the screen, after the adjustment of voltage
sensitivity band switch Y plates and time base band switch X plates . The horizontal
length l between two successive peaks is noted. When this horizontal length l is multiplied by the time base m i.e. sec div , we get the time period T .The reciprocal of
the time period 1 T gives the frequency f . This can be verified with the frequency,
measured by the multi meter.
