Which of the following is time-dependant? Group of answer choices dynamic model
static model

A dynamic model accounts for time-dependent changes in the state of the system,

while a static model calculates the system in equilibrium, and thus is time-invariant.

Dynamic models typically are represented by differential equations or difference equations

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.
