How is the amount of time spent sliding controlled in the simulations? how does it affect the ability of the vehicle to stop

The focal length of a relaxed human eye is approximately 1.7 cm. when we focus our eyes on a close up object, we can change the refractive power of the eye by about 16 diopters. (a) does the refractive power of our eyes increase or decrease by 16 diopters when we focus closely? explain. (b) calculate the focal length of the eye when we focus closely.

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.
