Awave with a period of three seconds travels at a speed of 12 m/s what is the wavelength of the wave

λ = 0.28m

Explanation:

Equation used is v = λf, where v is velocity, λ is wavelength, and f is frequency

We need to find wavelength so rearrange the equation in term of wavelength.

v = λf

λ = f/v

We know that period is the inverse of frequency (f = 1/T), so lets substitute that into our equation

λ = f/v

λ = (1/T)/v

Plug in your the given values given in the question.

We're given v=12m/s and T=3sec

λ = (1/T)/v

λ = (1/3)/12

λ = 1/36 = 0.2777777 = 0.28m

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:

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
