(a) Assume the equation x = At3 + Bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. Determine the dimensions of the constants A and B. (Use the following as necessary: L and T, where L is the unit of length and T is the unit of time.)

(b) Determine the dimensions of the derivative

dx/dt = 3At2 + B. (Use the following as necessary: L and T, where L is the unit of length and T is the unit of time.)

  • So, how do we describe diffusive motion? If a particular object moves a distance Ar from...

    So, how do we describe diffusive motion? If a particular object moves a distance Ar from its original location (displacement) in a time Δ t, we cannot write down an equation that precisely relates dr and Δ, since the direction and distance moved by the object between collisions with the fluid particles is random and the time between collisions is also random. Because of these random effects, a particular object has very little chance of ever returning to the position...
