Consider the s- operator (the spin operator in the z-direction), and the sy operator (the spin operator in the y-direction). a. in the z-basis: i. what is s, in matrix format? what is the z+ state in matrix format? show that z+ state is an eigenvector of sz. what is the eigenvalue? iii. what is sy in matrix format? iv. what is the y+ state in matrix format? show that y+ state is an eigenvector of sy. what is the eigenvalue? v. show that z+ state is not an eigenvector of sy. vi. show that y+ state is not an eigenvector of sz. b. in the y-basis: i. what is sy in matrix format? ii. what is the y+ state in matrix format? show that y+ state is an eigenvector of sy. what is the eigenvalue? is the y+ state in the y-basis, the same state as the y+ state in the z-basis? explain. iv. is the sy operator in the y-basis, the same state as the sy operator in the z-basis? explain.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
