The answer is attract. Hope it helps! :)
D.6.22N. because .42kg * 14.8m/s=6.22 N[meaning newtons}.
Answer:
In waves distance is measured by wave length and time is measured by frequency or period.
velocity ratio=wave length multiply by frequency.
HENCE, if the same wave travels for 2 econds its frequency will be 2Hz.
Explanation:
The change in velocity is +4 m/s to the right (or -4 m/s to the left).
The object's mass is irrelevant.
