Answer:
a) Velocity = 20m/s
b) Acceleration = 2m/s²
c) Force = 200N
Explanation:
a) Velocity acquired by the body
Formula for Velocity is given as = Distance / Time
In the question, Distance = 100m
Time = 5s
Velocity = 100m/ 5s
= 20m/s
Therefore, Velocity acquired by the body = 20m/s
b) Acceleration produced by the force is calculated as:
Formula for Acceleration = Velocity/ Time
Velocity is calculated as Velocity acquired by the body = 20m/s
Time = 10s
a = 20m/s / 10s
a = 2m/s²
Therefore, Acceleration produced by the force = 2m/s²
c) Force = Mass × Acceleration
From the above question,
Mass = 100kg
Acceleration = 2 m/s²
Force = 100kg × 2m/s²
= 200kgm/s² or 200 N(Newton)
Therefore, Force produced by the body = 200N
Answer: Structure-oriented studies.
Explanation:
Structure-oriented studies focus on relationships among variables as well as attempt to identify similarities and differences in these relationships across cultures and measure them.
In contrast to professional journalists, ordinary people report and spread news under the umbrella of citizen journalism.

Citizen journalism, according to specialists in the field, is the gathering and reporting of news via social media, open forums, and established news venues, whether from non-traditional sources or the general population. If they were to provide information about an incident, for instance, police officers or city clerks may act as citizen journalism. With the use of cellphones rising, citizen journalism has grown more and more widespread. Nevertheless, there is evidence of citizen journalism dating back to 1963.
