Answer:
0 J
Explanation:
Work = force × distance
Since the object isn't moved, the distance is 0. So the work is 0.
Answer:
266.67Watts
Explanation:
Time = 2.5hr to seconds
3600s = 1hr
2.5hrs = 3600×2.5= 9000s
Force = 32N
Distance = 75km to m
1000m = 1km
75km = 1000×75 = 75000m
Power = workdone / time
Work = force × distance
Therefore work = 32N × 75000m
Work = 2400000Nm
Power = work ➗ time
Power = 2400000Nm ➗ 9000s
Power = 266.67Watts
Watts is the S. i unit of power

Answer:
Distance
Explanation:
distance is in vertical axis,or y-axis and time is on the horizontal axis,or x-axis.
Answer: 1. Carbon dioxide is not an air pollutant
Explanation: it can be toxic and or safe
Explanation:
If g= 10m/s²
Then 75kg=75×10=750N
Since Work =Force ×Distance
Work=750×30
=22500J
And Power°=Work÷time
=22500÷120
=187.5W
