<span>Cr 2(52.0) = 104 O 3(16.0) = 48
104/152 * 100 = 68.42% Cr
48/152 * 100 = 31.58% O</span>
So,
Recall Newton's Second Law of Motion: force = mass x acceleration
Also recall:
acceleration = velocity/time
velocity = distance/time
Distance is expressed in meters.
Time is expressed in seconds.
Mass is expressed in kilograms.
v = m/s
a = m/s^2
F = m * a
F = kg * m/s^2

The unit for force is the Newton (N).
answer: it is true because a hypothesis is something you think will happen during a experiment
