Answer:
the period T of whole motion should be twice the value for half at he bottom so T is 0.2sec.
w is angular frequency
formula:2π/T
now k is spring constant
F/R-->mw²
putting values:70*(2π/0.2)²
=4.9x10⁶
so we can say that SHM is not affected by the amplitude of the bounce.
The magnitude of the acceleration of the ball while coming to rest is 477.43 m/s²
The direction of the acceleration of the ball is downwards
The given parameters
initial velocity of the ball, u = 0
height above the ground, h = 2.2 m
time of motion of the ball, t = 96 ms = 0.096 s
The magnitude of the acceleration of the ball while coming to rest is calculated as;
let the downwards direction of the acceleration be positive
The direction of the acceleration of the ball is downwards

<span>Greek philosophers had a basic approach to studying the world. They like to question the world and incite debates but they never really bothered to gather any real information, just discussions. Due to this, many ideas about matters were put out to be discussed, but they were never resolved.</span>
<span>the ratio of the force produced by a machine to the force applied to it, used in assessing the performance of a machine. I would say the answer is D, but i'm not sure. :)</span>
Answer:
The correct option is;
Biochemist → Archivist → Civil Engineer → Engineering Technician
Explanation:
1) Biochemist require the completion of a science degree or applied science degree, while biochemist usually hold a PhD to perform research independently, while entry level positions in the profession require a masters or bachelors degree
The PhDs usually require about 5 years to complete, after obtaining the masters degree
2) The general educational requirement to become an archivist is a master's degree in the fields of library science, history, public administration, political science, or archival science, which requires the completion of a bachelors degree followed by the completion of the masters degree which is thus 4 to 6 years
3) Civil engineer title is awarded to holders of a bachelors degree in Civil Engineering which gives the strong mathematical and science background required in the profession usually. The Civil Engineering program duration is five years
4) The engineering technician consist of 8.2% with masters degree, 42.0% have bachelors degree, while it is also possible to become an engineering technician with a GED or a high school degree
Therefore, the usual duration of study to become an engineering technician is two years of an associate degree program.
