Why is a lever important to a catapult?
BEcause it is a device helping to use it to throw.
What use is alpha radiation?
It is used in smoke detectors as it cannot travel far in air. Alpha radiation is emitted and as long as the detector in the device is receiving the alpha radiation, then no smoke is present. When smoke particles are present, they interrupt the radiation, and so the detector doesn't pick up the radiation, causing the alarm to go off.
What did the astrolabe navigation device use to determne direction latitude and local time?
the sun
Did Germany use radar in the Battle of Britain?
Yes, Radar helps detect aircraft & ships. The first well-known use was during the 1940 Battle of Britain when the British used Radar and visual spotters to detect German aircraft flying from France, Belgium, Netherlands, Denmark, and Norway towards Great Britain.
What did the telegraph use?
A device that could send information over wires across great distances
What did Rutherford use to detect radio activity?
Ernest Rutherford used a device called a scintillation counter to detect radioactivity. This device counted the flashes of light produced when radioactive particles interacted with a phosphorescent material. Additionally, he employed a gold foil experiment to observe the scattering of alpha particles, which further contributed to his understanding of atomic structure and radioactivity.
What are the differences between photoelectric and ionization smoke detectors?
Photoelectric smoke detectors use a light beam to detect smoke particles, while ionization smoke detectors use radioactive particles to detect smoke. Photoelectric detectors are better at detecting smoldering fires, while ionization detectors are more sensitive to fast-flaming fires.
What form of electromagnetic waves are used in smoke detectors?
There are two types of smoke detectors:Alpha particle - these do not use electromagnetic wavesPhotoelectric - these use a beam of either visible lightor near infrared electromagnetic waves
What device do you use to detect motion?
motion detector
Which device did Charles Wilson invent to detect subatomic particles?
He invented the cloud chamber (also known by the name Wilson chamber). Cloud chambers use supercooled water or alcohol to track the paths of subatomic particles.
What are the differences between a photoelectric smoke detector and an ionization smoke detector?
The main difference between a photoelectric smoke detector and an ionization smoke detector is the way they detect smoke. Photoelectric detectors use a light beam to detect smoke particles, while ionization detectors use radioactive particles to detect smoke. Photoelectric detectors are better at detecting smoldering fires, while ionization detectors are more sensitive to fast-burning fires.
What is a senor?
A magnetic device use to detect the revolutions of an entity.
What is a Speed senor?
A magnetic device use to detect the revolutions of an entity.
What are the differences between a photoelectric smoke alarm and an ionization smoke alarm?
The main difference between a photoelectric smoke alarm and an ionization smoke alarm is the way they detect smoke. Photoelectric alarms use light to detect smoke particles, while ionization alarms use radioactive particles. Photoelectric alarms are better at detecting smoldering fires, while ionization alarms are more sensitive to fast-flaming fires.
Can chemical reaction produce radioactive particles?
Yes, some chemical reactions involving radioactive elements can produce radioactive particles as products. These radioisotopes may emit radiation as they decay, posing health risks if not handled properly. It is important to use caution and proper safety measures when working with radioactive materials.
What are the differences between photoelectric and ionization smoke detectors in terms of their detection mechanisms and effectiveness in detecting smoke particles?
Photoelectric smoke detectors use a light beam to detect smoke particles, while ionization smoke detectors use radioactive particles. Photoelectric detectors are better at detecting smoldering fires, while ionization detectors are more sensitive to fast-flaming fires. Overall, photoelectric detectors are considered more effective in detecting smoke particles.
What counts radioactive material?
Radioactive materials are substances that contain unstable nuclei that can undergo radioactive decay, releasing energy in the form of radiation. Common examples include uranium, plutonium, and radium.
