Draw each of the following vectors. Then find its x and y components. a= (3.5 m/s^2, negative x direction)
v= (440 m/s, 30 degrees below the positive x-axis)
r= (12m, 40 degrees above the positive x-axis)

total distance/total time

(85 + 82)/(5+3)

the given statement is true.

sensory memory lasts for a fraction of seconds before the information is lost. it is the shortest -term memory and can be called as an element of memory. example: when we look at something and remember what it looks like, is just a second of observation. it degrades very quickly. it can also be considered as the process of perception rather than considering it as a memory.
