Octal 124
When did the Lusitania leave port the final time?
The Lusitania departed Pier 54 in New York on May 1, 1915.
What is the difference between a 54AS139 and a 74As139 integrated circuit?
The 54 series are military specification versions with a greater operating temperature range.
An elastic cord is 63 cm long when a weight of 54 N hangs from it but is 84 cm long when a weight of 81 N hangs from it What is the spring constant k of this elastic cord?
solution:: using Kx = F =mg 1] K .(0.63- l ) =54 2] K . (0.84 - l ) = 81 solve these two eqns to get the natural lenght as well as the spring constant
What is the main difference between VHF and UHF?
VHF uses the 6 Meter Band (50-54 Mhz), the most popular VHF band - 2 Meter Band (144-148 Mhz) and the 1 1/4 Meter Band (222-225). UHF uses the most popular UHF band - 70cm Band (420-450 Mhz), the 902-928 Mhz area and the 1200-1300 Mhz area.

What frequency does RF waves fall in used by commercial radio broadcasting stations?
There are basically two radio broadcast bands as we know them. One is the AM (amplitude modulation) band, and the other is the FM (frequency modulation) band. The AM band is from 520 KHz to 1700 KHz (0.52 MHz to 1.7 MHz). The FM band is from 87.5 MHz to 108.0 MHz. Other bands are used commercially, but these two bands represent the broadcast bands used in the U.S.Note: 1 KHz = 1,000 Hz (Hertz, cycles per second, or cps), and 1 MHz = 1,000,000 HzIn the USA ...-- Commercial AM radio stations operate with carrier frequenciesspaced every 10 KHz between 550 KHz and 1700 KHz.-- Commercial FM radio stations operate with carrier frequenciesspaced every 200 KHz between 88.1 MHz and 107.9 MHz.
What is the frequency of MTV?
Television broadcasts on a variety of different frequencies depending on the channel. Each channel occupies an approximately 6 MHz wide band of frequencies. In the US, channel 2 (there is no channel 1) starts at 54 MHz. Channels 3 and 4 follow at 6 MHz intervals (ending at 72 MHz for the top end of channel 4), then there's a gap before channels 5 and 6 in the 76-88 MHz range. There's then a much bigger gap (containing, among other things, FM radio and commercial aviation radio) before channels 7-13 at 174-216 MHz. There's then an even bigger gap before the UHF frequencies (channels 13-51) at 740-698 MHz. The former TV channels 52-83 (698-896 MHz) have been reassigned to other purposes such as cell phones and commercial two-way radio.
What is the maximum frequency of a radio wave?
Commercial AM radio stations (in the USA) operate on carrier frequencies spaced every 10 KHzbetween 550 KHz and 1.65 MHz.Commercial FM radio stations operate on carrier frequencies spaced every 200 KHz between88.1 MHz and 107.9 MHz.Commercial analog TV used to start at 54 MHz and get 6 MHz for each channel, with gaps forother services. Since the forced mass exodus to all-digital TV in June '09, I don't know wherethe TV's all are now.
What is the radio frequency of TV?
Depends on the channel and whether analog or digital transmission. Analog channel-2 is the band 54-60 MHz. The video information is a single AM (upper) sideband about 4.2 MHz wide, with a small sniff of carrier transmitted at 54.25. The audio is on an FM carrier centered at 58.75 and deviated 25 KHz peak. (That's the layout for analog TV, which no longer exists. I have as yet no clue regarding the workings of digital TV.) All the rest of the 65 channels extend from here up to about 800 MHz. (Not all of this range is allocated to TV broadcast, but every TV broadcast channel is somewhere in this range.)
What radio band and speed does 802.11a use?
802.11a uses a 5.0 frequency and supports 54 Mbps, and doesn't encounter interference from cordless phone, microwave ovens, and bluetooth devices.
Standard speeds supported by 802.11x?
Standard speeds supported by 802.11x are 802.11a up to 54 Mbps, 802.11b up to 11 Mbps, 802.11g up to 54 Mbps and 802.11n up to 150 Mbps. These speeds are determined by the frequency band of the connection.
What type of waves does a television use?
Radio waves. A section of the frequency spectrum is reserved for broadcast television. Television signals are transmitted in the VHF (Very High Frequency) range using frequencies from 54 Mhz to 216 Mhz with a section in the middle (88 to 108 Mhz) assigned for FM radio broadcasts. The VHF frequencies were used to accommodate the wide bandwidth needed for the analog video and audio signals. Each broadcasting channel was alloted a 5 Mhz range for audio and video and to allow separation from adjacent channels so that they would not interfere with each other. The US has since switched from analog to digital television broadcasts but is still using the same VHF frequency range.
What standards speeds are supported by 802.11x?
Standard speeds supported by 802.11x are 802.11a up to 54 Mbps, 802.11b up to 11 Mbps, 802.11g up to 54 Mbps and 802.11n up to 150 Mbps. These speeds are determined by the frequency band of the connection.
How do you communicate with astronauts if radio waves are reflected back to earth?
Radio signals at frequencies up to roughly 40 to 60 MHz are absorbed or reflected from the ionosphere. At higher frequencies, the signals easily penetrate the ionosphere and continue on into space. This is the reason that AM radio (1 MHz) and "short-wave" broadcasts (4-13 MHz) are often received from great distances, but TV (54 MHz and up) and FM radio (100 MHz) are not.
Which is longer am radio waves or tv waves?
AM radio operates at 500-1500kHz, which translates to 600-200 m wavelengths. TV uses several non-contiguous frequency bands starting at 54 MHz which translates to wavelengths of 5.556 m and below. Clearly AM radio has much longer wavelengths.
