Consider the secular equations relating the coefficients and energies of two interacting atomic orbitals below:
(\alphaa - e)ca + (\beta - es)cb = 0
(\beta - es)ca + (\alphab - e)cb = 0
1) briefly describe in words what \alpha , \beta , and s represent. in what situations are their values smaller or larger?
2) for a homonuclear diatomic molecule like h2, the values of \alpha a and \alpha b are equal (let’s define them both as \alpha ). what are the energies of the bonding and antibonding orbitals in terms of \alpha , \beta , and s? (hint: solve the secular equations for ca/cb. for each possible value of ca/cb, solve for the molecular orbital energy e.

the force on the thing and the distance the force moves the thing

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.
