A60 vibration per second wave travels 30 meters in one second. what is its frequency and wave speed?

frequency: 60 Hz, speed: 30 m/s

Explanation:

- The frequency of the wave is equal to the number of complete vibrations per second. For the wave in the problem, we have 60 vibrations per second, so the frequency is

- The speed of a wave is given by

where d is the distance travelled and t the time taken. The wave in this problem travels a distance of d=30 m in a time of t=1 s, so the speed of the wave is

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.

explanation:

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
