| 31. | Assuming the fan is mains-powered, then that current is alternating at 50 or 60 hertz ( cycles per second ).
|
| 32. | For example, when thalamic cells reverberate at two cycles per second, the brain is in a state of deep sleep.
|
| 33. | This would allow about 160 half-duplex lines running at a mean speed of 120 cycles per second ( cps ).
|
| 34. | It should be easy to see now that a 200MHz processor is capable of executing 200 million cycles per second.
|
| 35. | Musicians worldwide generally agree that an A is a sound you get when a tone resonates at 440 cycles per second.
|
| 36. | :An approach that I would find more interesting would be like the 3D glasses that block transmission many cycles per second.
|
| 37. | The fins are normally configured so that the rocket will have a stabilizing spin rate of approximately four cycles per second.
|
| 38. | She said that normal speech is carried out at audiofrequencies between 500 and 2, 000 hertz ( cycles per second ).
|
| 39. | But because of limitations on transistor speed, doing more per cycle means you have to reduce the number of cycles per second.
|
| 40. | For example, when rats are threatened, they emit very high frequency ( 20, 000 to 30, 000 cycles per second ) screams.
