It is important to properly balance a centrifuge because an unbalanced machine can damage the rotor, cause catastrophic damage to the machine itself, or even injure or kill lab personnel working in the room. Balancing a centrifuge involves spreading the weight of the samples across the entire rotor.

Answer:
20.996 m
Explanation:
Given:
Initial velocity, 
Final velocity, 
Total time taken,
s.
∴ Acceleration is given as,
m/s²
Now, using Newton's equation of motion, we find the displacement.
Displacement is given as:

Plug in 0 for
, 4.91257 for
and 1.74 for
. Solve for
.
This gives,

Therefore, the train's displacement in the first 4.91257 s of motion is 20.996 m.
newton's second law states that an object accelerate only when there is a net force acting on it. this law is important in studying motions where the speed increases at constant rate or decreases at constant rate.
newton's third law states that for every action there is equal and opposite reaction. this law helps in understanding why a person gets injured while punching a wall with some force.
Answer:
g = 5 m/s square
Explanation:
Weight(W), Mass(m), Gravity(g)
W = mg
1,000N = 200g
g = 1000/200
g = 5 m/s square
