Derive the concentration profile as a function of radial distance from the dissolving sphere and its variation over time. assume one-dimensional diffusion of species a in a binary mixture occurs from the spherical particle is radially outward and assume quasi- steady process. assume newtonian fluid if it , assume all the physical properties are known including solubility (c) and ignore the temperature dependence of the physical properties of the polymers and the oil.

The famous scientist galileo galilei did several experiments with sloping planes, which he rolled metal balls down so that he could study motion. by changing the slope, he could study how the speed at which the ball rolled was affected. what was the independent variable in galileo's experiment? a. the speed of the ball b. the slope of the plane c. whether the ball moved d. what the ball was made of

What is the name of the enzyme that forms at the start of transcription?

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
