3. A certain ocean wave has a frequency of 0.07 hertz and a wavelength of 10 meters. What is the wave's speed?
a: 1.0 m/s
b. 10 m/s
c 143 m/s
d. 0.70 m/s
e.
0.07 m/s

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)

explanation:

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.
