Awoman is standing in the ocean, and she notices that after a wave crest passes, five more crests pass in a time of 50.0 s. the distance between two successive crests is 32 m. determine, if possible, the wave's
(a) period.
(b) frequency.
(c) wavelength.
(d) speed.
(e) amplitude.
if it is not possible to determine any of these quantities, then so state.

Answer

given,

number of crest (N)= 5

time(t) = 50 s

distance between to successive crest = 32 m

a) Period

b) frequency

c) wavelength

   distance between to consecutive crest is wavelength

    wavelength = 32 m

d) speed

         v = f λ

         v = 0.1 x 32

         v = 3.2 m/s

e) Amplitude

    We cannot determine amplitude because data is not given.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
