What happens when you force magnets together?
What happens when you force magnets together? When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. Like charges repel, and unlike charges attract. Since a free hanging magnet will always face north, magnets have long been used […]
What are the 4 types of galaxy?
What are the 4 types of galaxy? In 1936, Hubble debuted a way to classify galaxies, grouping them into four main types: spiral galaxies, lenticular galaxies, elliptical galaxies, and irregular galaxies. Is space really colorful? Space emits a range of wavelengths of light, some we can see others we can’t. However it doesn’t record any […]
Where do ferns grow best?
Where do ferns grow best? Light. Most ferns prefer a shady location, but they don’t do well in deep shade. The dabbled shade provided by tree branches provide the best conditions. Think about how they grow in the forest and try and find similar conditions in your yard. How do ferns adapt to life in […]

The oceans contains 97% of Earth’s water, and oceanographers have stated that less than 20% of the oceans have been mapped….Oceanic divisions. […]
How do you fix a compass with reverse polarity?
How do you fix a compass with reverse polarity? It is possible to ‘reverse’ the reversed polarity using a strong magnet. This can be achieved by quickly flicking the magnet outwards along the ‘north’ end of the needle. Repeat vice-versa. Always ensure you compare with a compass that is known to be correct. What is […]
Why is the inverse square law is important?
Why is the inverse square law is important? Inverse Square law: The radiation Intensity is inversely proportional to the square of the distance. Therefore, while the inverse square law pertains to radiation safety, it also helps us to determine source to film distances (SFD), time of x-ray exposure, and the intensity (KV) of our x-ray […]
When the magnitude of the resultant of two vectors is maximum?
When the magnitude of the resultant of two vectors is maximum? Notes: The magnitude of the resultant of two vectors is maximum when vectors act in the same direction. The magnitude of the resultant of two vectors is minimum when vectors act in the opposite directions. What is the formula of resultant force? Resultant force […]
Are fire wardens a legal requirement?
Are fire wardens a legal requirement? The Regulatory Reform (Fire Safety ) Order 2005 made it a legal requirement. All staff members in a business environment had to receive at least some form of basic fire warden training.

Why is removal of hydrogen oxidation?
Why is removal of hydrogen oxidation? Gain and Loss of Hydrogen Both carbon-containing molecules have the same oxygen content, but the formation of the formaldehyde is seen to be oxidation because hydrogens are lost. The formation of H2 is a reduction process as the two released hydrogens get together. What is oxidation and reduction in […]
