FinnZ [79.3K]

Answer:

Explanation:

A general wave function is given by:

f(x,t)=Acos(kx-\omega t)

A: amplitude of the wave = 0.075m

k: wave number

w: angular frequency

a) You use the following expressions for the calculation of k, w, T and λ:

\omega = 2\pi f=2\pi (2.00Hz)=12.56\frac{rad}{s}

k=\frac{\omega}{v}=\frac{12.56\frac{rad}{s}}{12.0\frac{m}{s}}=1.047\ m^{-1}

T=\frac{1}{f}=\frac{1}{2.00Hz}=0.5s\\\\\lambda=\frac{2\pi}{k}=\frac{2\pi}{1.047m^{-1}}=6m

b) Hence, the wave function is:

f(x,t)=0.075m\ cos((1.047m^{-1})x-(12.56\frac{rad}{s})t)

c) for x=3m you have:

f(3,t)=0.075cos(1.047*3-12.56t)

d) the speed of the medium:

\frac{df}{dt}=\omega Acos(kx-\omega t)\\\\\frac{df}{dt}=(12.56)(1.047)cos(1.047x-12.56t)

you can see the velocity of the medium for example for x = 0:

v=\frac{df}{dt}=13.15cos(12.56t)

BabaBlast [244]

Answer:

C. Metabolism

Explanation:

Although it is a process that we cannot visualize, we feel it daily in our day by day life. A clear example is when we consume food of any kind, each of these foods contains a reference amount of energy in kilocalories (kcal). These foods supply energy to the human body, this energy from food is used for different day actions, and much to maintain body temperature. When the human body is exposed to very low outside temperatures, the body is exposed to a considerable loss of energy in the form of heat transfer, so the person will begin to feel hungry so that the body needs calories from food to maintain body temperature at stable levels. Metabolism is essential in the human body, at the moment when the human being dies his temperature decreases because the metabolism stops working.
