Amplification factor r(k) for spinodal decomposition has the following dependence on wave vector k: r\left ( k \right )=-lk^2((\frac{d^2g}{dx^2})_x=_x_0+ 2kk^2)
find the value of km corresponding to the fastest growing wavelength (related to a maximum of r). connect it with kc - critical wave number for start of spinodal decomposition (r(kc)=0). give qualitative explanation why km

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
