A 74.0-kg man stands on a bathroom scale inside an elevator.(a) The elevator accelerates upward from rest at a rate of 1.10 m/s2 for t1 seconds. What does the scale read during this time interval

806.6 N

Explanation:

Given that :

Mass (m) = 74 kg

Acceleration due to gravity (g) = 9.8 m/s²

Acceleration during interval t1 = 1.10 m/s²

Using the relation :

Normal reaction = Mass (g + acceleration at interval t1)

Normal reaction = 74(9.8 + 1.10)

Normal reaction = 74(10.9)

Normal reaction = 806.6 N

answer; /// the above statement is (true);

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
