The time between stimulation of muscle cells and force generation is called

muscle contraction

Explanation:

A muscle contraction is the reaction of tension-generating sites within muscle fibers. This occurs during the length of time of the muscle, generating a force at the origin.

explanation:

ok

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
