An infinite uniform non-multiplying medium has the following properties: diffusion length 8cm, diffusion coefficient 1.4 cm. there is an infinite plane source on the y-z of plane strength 13 106cm-2.s-1 and two point sources on the x. y plane as follows source: 82 = 107 s-1 at (x, y) = (1,0)cm s,-107s-1 at (x, y) = (2,0)cm a. calculate the total flux at the point (xn =(1.5,0.5) cm on the x-y plane. flux- b. what is the magnitude and the direction of the total current at the same point current magnitude- current directions:

v=ir = 3x15 =45 v

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.
