I’m not good with physics but I’m good with the theory what goes up must come down
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.

Answer:
(a) t = 1.14 s
(b) h = 0.82 m
(c) vf = 7.17 m/s
Explanation:
(b)
Considering the upward motion, we apply the third equation of motion:

where,
g = - 9.8 m/s² (-ve sign for upward motion)
h = max height reached = ?
vf = final speed = 0 m/s
vi = initial speed = 4 m/s
Therefore,

<u>h = 0.82 m</u>
Now, for the time in air during upward motion we use first equation of motion:

(c)
Now we will consider the downward motion and use the third equation of motion:

where,
h = total height = 0.82 m + 1.8 m = 2.62 m
vi = initial speed = 0 m/s
g = 9.8 m/s²
vf = final speed = ?
Therefore,

<u>vf = 7.17 m/s</u>
Now, for the time in air during downward motion we use the first equation of motion:

(a)
Total Time of Flight = t = t₁ + t₂
t = 0.41 s + 0.73 s
<u>t = 1.14 s</u>
Answer:
Explanation:
Let's look at a mathematical representation of this. The equation for tis is just a souped up version of Newton's 2nd Law:
F - f = ma. It an object is moving at a constant speed, the acceleration of that object is 0. That changes this equation to
F = f which states that the applied Force equals the frictional force, choice a.
