Answer:
<em>c = -30 N</em>
<em />
Explanation:
Initial length L1 = 30 cm
Initial restoring force F1 = -35 N
Final length L1 = 90 cm
Final restoring force F2 = -125 N
Between 30 cm and 90 cm, one will increase extension by 20 cm 3 times. This means the force between -35 N to -125 N increased by 3 constant value.
-125 - (-35) = -90 N.
this means that the constant is,
<em> c = -90/3 = -30 N</em>
<em>This means that for every 20 cm increase, there is a 30 N decrease in the restoring force</em>
Answer:
Explanation:
the equation you use here is m=fa or mass=force x acceleration
you plug in the 13.5 N as the force, 6.5 m/s^2 as the acceleration, and do the math.
13.5 x 6.5
That would equal 87.75 which would be your answer.
Answer:
4:5
Explanation:
If M is 20% less than N, then we can think of M as being 80% of N. This gives us a ratio of 80:100 (80% to 100%, 20% less), which can then be simplified to the ratio 4:5.
Hope this helped!
