The hubble space telescope is a reflecting telescope that was placed in orbit above the earth’s atmosphere, so its resolution would not be limited by turbulence in the atmosphere. its objective diameter is 2.4 m. for visible light, say λ = 550 nm, estimate the improvement in resolution the hubble offers over earth-bound telescopes, which are limited in resolution by movement of the earth’s atmosphere to about half an arc second. (each degree is divided to 60 minutes each containing 60 seconds, so 1◦ = 3600 arc seconds).
question (1) d. hunted with stone-tipped spears
question (2) a. developed widespread agriculture
the answers would be chunking & short-term
1. chunking involves organizing and breaking down information into easier groups to expand capacity.explanation:
chunking is a mental process that is observed to increase short-term memory by taking the information and categorizing it into small groups. for instance, a longer number taken as a single unit is harder to recall then when it is divided into smaller units. 235469350 is harder to instantly recall as compared to when it is chunked into 3 groups: 235 469 350.
this allows more information to be stored in, thereby increasing the capacity of the mind to store information.
2. rehearsal is the verbal repetition of information. these techniques are especially important for the improvement of short-term memory.explanation:
short-term memory is lost after a couple of seconds or minutes, for instance even if you chunk the information, you might not recall it after 30 seconds. rehearsing or repetition of information, either loudly or mentally, extends the time a particular information is retained.
so you depending on the number of times you repeat the number 235 469 350, the more your short term memory improves .
hope this !
