If an object moves with a constant velocity, what is the acceleration of the object? what is the net force acting on the object?

True or false a high force means an object is moving fast100 points!

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.
