Answer:
1980 kg m/s due south
8.2 m/s2 north-west
Explanation:
In order a quantity to be a vector, it should both has a magnitude and direction.
27 J/s --> Only magnitude. (Power)
1980 kg m/s due south --> Both magnitude and direction. (Momentum)
8.2 m/s2 north-west --> Both magnitude and direction. (Acceleration)
3.2 mi straight up --> Direction is not clear. (Position)
2.9 m/s2 --> Only magnitude. (Magnitude of acceleration)
293 K --> Only magnitude. (Temperature)
200 s --> Only magnitude. (Time)
Answer:
If research results can be replicated, it means they are more likely to be correct.
Answer:
i don't know how to explain it but I think it's just the way you do it by yourself
It would be because at the surface of the earth, the acceleration due to gravity is roughly 9.8m/s. so the answer would be D,
