Answer:
The person has no displacement
Explanation:
The given parameters are
The location of the person = The equator
The distance covered in one revolution = Total distance around the body
The total distance around the Earth = The circumference of the Earth = 40.075 kilometres
The total distance moved by the person standing at the equator during the Earths complete revolution = 40,075 kilometres
The initial location of the person in relation to a fixed point in space outside Earth at the start of the revolution = x km
The final location of the person in relation to the fixed point in space outside Earth at the completion of the revolution = x km
The displacement = Change in position = Final location - Initial location
∴ The displacement = x km - x km = 0 km.

<h3><u>Answer;</u></h3>
18 Joules
<h3><u>Explanation;</u></h3>
- <em><u>Work is the measures the transfer of energy when an object moves over a given distance.</u></em>
- Work is therefore given by; Force × distance
Force =36 Newtons
Distance = 0.5 meters
- Hence; <em>work = 36 N × 0.5 N</em>
<em> = 18 Joules </em>
