It should be 0.25kg because you converter from g to kg and since 1g<1kg so you move the decimal to the left
Answer:
because speed is the modulus of velocity which is a vector
the velocity to be zero it must be a round trip
Explanation:
This is because speed is the modulus of velocity which is a vector.
For the velocity to be zero it must be a round trip, therefore the resulting vector zero
On the other hand, the speed of the module is the same in both directions
I think its B or D, most likely D.
