It will change the way we do normal things such as going to certain stores, have arrows showing what lane you can go down, not being able to leave the country for awhile, and social interaction
Answer:
Explanation:
The difference between top and bottom surfaces is computed by the following hydrostatic equivalence:
W = F x d/x = (m x Ag) x h, therefore, mass (2kg x 9.8) x 2.5m = 49J
Sonography is most likely because it has good resolution without radiation.
<span>The period of a wave can be calculate according T = 1 / f
where T is wave period and f is frequency,
then in our problem we have a wave of 100 Hz so:
T = 1 / 100 = 0.01 seconds
The wave have a period of 0.01 seconds.
Optinaly we could also calculate the speed: V=wavelenght/period= 2/0.01= 200 m/s</span>
