Mabye a walkie-talkie or radio. I am not sure.
In order from top to bottom, the major modes are: User executive mode Privileged executive mode Global configuration mode Other specific configuration modes
Well Airborne RADAR works in similar manner as their Ground counterpart , the differences typically lies in mode of operations, processing software , physical size and functions .usually Airborne RADAR's , especially for those who's required to detect target that flies at low altitude uses Doppler measurements to differentiate between target and steady objects like grounds . It's also may have a "compensations" to correct tracking error caused by the carrier's own movement EDIT- It seems the previous answer is bit too complex for some people Air to Air airborne radar uses combinations of range ambiguous and Doppler ambiguous modes. High Pulse Repletion Frequency (HPRF) modes which are range ambiguous, to measure Doppler unambiguously. Low Pulse Repletion Frequency (LPRF)modes measure range unambiguously both of these modes still measure both Range and Doppler and resolve the ambiguous measurement using Chinese remainder theorem. This resolving of the ambiguous measurement uses different measurement parameters that are not related provide a measurement remaining that can be related to unfold Range or Doppler measurements. In between the HPRF and LPRF is the Medium Pulse Repetition Frequency Mode which are both Range and Doppler ambiguous. Repetition Rate of Pulses adaptation can be mixed together and sequenced. Some modes are have better properties then others for measuring particular targets or characteristic of some targets. The question of ambiguity, and therefore what defines a Pulse Repetition Frequency as High Medium or Low is dependent on the target characteristic and the range you wish to measure to.
The half-life of 214Bi is 19.7 minutes. However, it has two decay modes, neither of which leads directly to lead; that complicates things. One of the decay modes leads to 214Po, which then quickly (half-life 0.0016 seconds) decays to 210Pb. The other one leads to 210Tl, which has a half-life of 1.3 minutes and also decays to 210Pb. So: Half of the 214Bi will be gone in 19.7 minutes; a bit after that half the sample will be 210Pb.
as the helium and hydrogen gas has the smallest atomic build among every thing in universe, they can escape from even solid metallic cups... deep sea divers if they are diving in deep sea for a long time, they must go under various decompression modes which some times take more than a day... during these decompression modes they have to breath oxygen mixed with helium or hydrogen to prevent nitrogen bubling in their blood causing death or paralysis instead of normal air mixture like oxygen and nitrogen as these decompression gasses can escape everything to known universe they can go in to the even best sealed diving watches... after the decompression period it was a well known issue that these diving watches were blowing their Christals up causing injuries or at least damaging the surroundings and these prestigious watches due to helium or hydrogen build up in them... to prevent that, some deep sea watches have a one way valve letting the excessive presure out as a solution to this problem which is called ''gas escape valve''
To set the time 1. Hold the reset button until the hour mode (12/24) is flashing 2. Press the mode button to scroll (year, month, day, hour) 3. Use the ST/STP button to advance 4. Press reset button to return to normal operation To set the alarm 1. Press the mode button to scroll to AL1 mode 2. Press the reset button to scroll through the 3 alarm modes 3. When alarm mode is displayed hold the reset button until the time is flashing 4. Use the ST/STP button to advance 5. Press reset button to return to normal operation Note: To change AM to PM you must advance through a complete 12 hour cycle.
Radio is the only way we have of communicating with astronauts or machines in space.
Two astronauts sitting in the same space ship can communicate by mouth ... at least while it's full of air ... or by passing notes. As soon as they put on their space suits, though, or if they feel like talking to anyone on earth or in another spaceship, radio is the only way. However, they could revert back to "archaic" technologies like sign language or perish the thought semaphore.
