The beam in a cathode ray tube is moved by an electric force. what did
scientists infer about atoms from this experimental result?
a. atoms are small particles that cannot be destroyed or divided.
b. atoms have a dense, positively charged center
c. electrons have more energy the farther they are from the nucleus.
d. atoms are made up of smaller particles.
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 !
work is a product of force and displacement. the choice with displacement but in a different direction is not right as force not acting along the displacement will not generate work.
so the answer is force in the same direction as the displacement vector and the motion.
