When Rebopy, a network service provider, started providing 4G data services, it attracted a large number of customers because of the high speed and cost-effectiveness of Rebopy's services. However, after a few months of using the service, the customers found that it had poor connectivity and hence switched to more efficient data services. In the context of innovation streams, which of the following concepts does this scenario best illustrate?
a. The compression approach to innovation
b. Technological singularity
c. Technological lockout
d. The experiential approach to innovation

Technological lockout

Explanation:

Technological lockout refers to the inability of a company to competitively sell its products because it relies on old technologies or a non-dominant design. It has also been defined by Melissa A. Schilling (1998) as 'a situation in which a firm finds itself unable to develop or competitively sell products to a particular market because of technology standards'. The 4G design is non-dominant and Rebopy clearly does not have what it takes in terms of technical know-how to deliver effective 4G services hence they are locked out of the network service market by other service providers.

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.
