Answer:
D. Position
Explanation:
10 m/s to the north means that an object is moving to the north and it doesn't matter neither the time nor the velocity.
This statement is just telling us the direction in which this object is moving.
Many ways for example they look up related things and study them or they can test it and see what happens
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
