Answer:
If there was no current, Frank would swim at the same rate of kilometers per hour.
Explanation:
Given that Frank swam the same amount of kilometers against the current and with the current in the same time, then we realize that the current is a variable that does not affect Frank's swimming speed. So if there was no current, it would surely swim the same amount of kilometers at the same time.
This is false. Your hypothesis, or prediction, is just that: a prediction. Saying its a failure will result in bias.
Answer:
the answer is 558.6N
Explanation:
the gravity on earth is 9.8.
W=MG
W=57g×9.8M/s
w=558.6N

-2 m/s^2 for particle A and -0.50 m/s^2 for particle B.Justification:</span>The graph for this question is attached to this answer.
Accelaration is the rate of change of velocity per time.
Particles A and B have different acceleration as their lines velocitty vs time are different.
The straight lines show that the motions of both particles are uniformly accelerated.
The acceleration of each particle will be the slope of its specific line.
For particle A, the slope is:
acceleration = slope = Δv / Δt = [0 - 2] m / [1 - 0] s = - 2 m/s
For particle B, the slope is:
acceleration = slope = Δv / Δt = [0 - 1]m / [2 - 0]s = - 0.5 m/s
