The frap technique occurs in a series of steps. select every statement that correctly describes a step in the frap procedure. choose one or more:

a. all fluorescent molecules in the cell are irreversibly bleached.

b. the molecule of interest is fluorescently labeled.

c. the relative mobility of the fluorescently labeled molecule is measured.

d. the speed of repair of the fluorescent marker is measured.

Ben(55 kg) is standing on very slippery ice when junior(25kg) bumps into him. junior was moving at a speed of 8m/s before the collision and ben and junior embrace after the collision. find the speed of ben and junior as they move across the ice after the collision .

(a) assume the equation x = at^3 + 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 = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
