Air moves out of the lungs when the pressure inside the lungs is equal to the pressure in the atmosphere. greater than intraalveolar pressure. less than the pressure in the atmosphere. less than intrapulmonic pressure. greater than the pressure in the atmosphere.

Greater than the pressure in the atmosphere.

Explanation:

Air moves from the region of higher pressure to that of its lower pressure. To move the air out of the lungs during exhalation, the intrapulmonary pressure (pressure inside the lungs) is increased above the atmospheric pressure. This is achieved by relaxation of the diaphragm and the external intercostal muscles relax. The chest and lungs recoil and the alveolar pressure inside the lungs increases above atmospheric pressure. This pressure gradient allows the air to move outside the lungs during exhalation.

relationships aren't everything. people everyday spend there entire life depending on reltionships and for someone to be there for them when this is absurd. why must people depend on someone else to bring them happiness? i'm not saying it wrong to feel happy with someone, but people feel that they need to be in a relationship in order to feel happy, when, this is not true. you can paint, write, read ir slend tume with family ir even spend time working in yourself. this can be an exciting experience to find yourself. it's bot wrong to be in a relationship but if you let it be your only source of happiness, than you will never find true happiness.

so, relationships are not always worth it. if you are so dependent on them, than in the end they arent worth it because you will realize how unhappy you really were. some people even tend to cut ties with family because they think they cabt make them happy, obly realtionships with a lover can. false. in order to find true happiness, one must learn to love themselves if they want to love someone else. it's unhealthy to be always depend on relationships and to alqays be in and out of one.

so live life, get that job you always wanted, buy those new shoes and love yourself. depend on yourself, not others. they arent worth it, you can make yourself more happier than most people can do to you. it's not woth it. take your time and have fun.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
