At the age of 33, ricky is a senior partner in a law firm. he lives alone in his apartment and does not find the time to socialize. he has a lavish home with an elaborate security system, and he owns a luxurious sports car. according to maslow's hierarchy of needs theory, which of the following can best explain ricky's discontentment with life? multiple choice a) ricky's physiological needs are not being met. b) ricky's need for belongingness is not being met. c) ricky's esteem needs are not being fulfilled. d) ricky does not feel safe at home.

b) Ricky's need for belongingness is not being met.

Explanation:

Maslow proposed a theory based on a hierarchy of needs, this hierarchy is often depicted as hierarchical levels within a pyramid.

According to Maslow, needs lower down in the hierarchy need to be satisfied in order to focus in needs that are higher up in the pyramid.

The needs are:

Physiological: refer to biological needs for human survival (food, warmth, sleep, etc)Safety needs: refer to protection from elements (security, order, stability)Love and belongingness needs: These has to do with the need for interpersonal relationships. (friendship, intimacy, love)Esteem needs: these needs refer to the need for respect or reputation (achievement, mastery, status).Self-actualization needs: Refer to realizing one own's potential and self-fulfillment. "To become everything one is capable of becoming"

According to the example, Ricky has a lavish home with an elaborate security system and he owns a luxurious car. We can see that his safety needs (security) are being met.

Also since he is a senior partner in a law firm with a luxurious car, we can say that his esteem needs are being met too (achievement, status).

However, he lives alone and does not find the time to socialize, thus, there are no real interpersonal relationships in his life.

We can conclude, based on this that Ricky's belongingness needs are not being fulfilled and this could explain his discontentment with life.

The light bulb was the invention that destroyed the first market for petroleum.

In the past, petroleum, instead of electricity, was  used to light homes, any kind of buindings and streets prior to the invention of light bulbs. Then, when the light bulb arised and was spread, the need for gas lighting decreased, giving rise to the destruction of the first market for petroleum.  

In 1802, Humphry Davy invented the first electric light. He experimented with electricity and created an electric battery.
