C.) It was Einstein who created quantum of light
There are 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms in one molecule of C12H22O11.
In five molecules there are 60 carbon atoms, 110 hydrogen atoms, and 55 oxygen atoms.
Answer:
Darker colored items absorb more of the sunlight.
Explanation:
Lighter colored item tend to reflect more of the sunlight
Answer:
Aluminium metal reacts vigorously with all the halogens to form aluminium halides. So it reacts with chlorine, bromine, and iodine.
Answer:
- The main idea behind MADs is that they use the principle that metallic objects (submarines) interfere in the magnetic lines of Earth forces. And this equipment detects this anomaly.
- Submarines can be detected by using MADs
- The history of MAD development
In 1917 the interest in the detection of submarines started with the study hydrophones. Then in 1918, the U.S. considered to use the magnetism in this area but it did not result to be practical as it had a limited detection range.
Then by 1941 in Britain and in U.S. developed magnetic detection devices to measure Earth’s magnetic field, so after that in 1943 MADs were installed in ASW aircrafts.
Due to the limited range and its lack of ability to detect the magnetic variance from different sources, MAD started to be used in combination with sonobuoys. This combination allowed an aircraft to localize submarines with the confirmation of sonobuoys.
Explanation:
MADs are Magnetic Anomaly Detectors. Their function is to detect anomaly in the Earth’s magnetic field caused by submarines.
Submarines are made of ferrous metal which contain domains that are tiny magnets form of iron molecules. This material creates a disturbance that can be detected in the magnetic field.
