Answer:
2.14 s
Explanation:
The period is the time for 1 revolution. If it takes 21.4 seconds to make 10 revolutions, then it takes 2.14 seconds to make 1 revolution.
You can show this with a proportion:
t / 1 rev = 21.4 s / 10 rev
t = 2.14 s
Answer:
x(spring stretch)=1.74×10⁻³ meter
Explanation:
Given Data
l (length)=0.175 m
v (speed)= 3.86 m/s
x₁(stretch)=0.0140 m
x(spring stretch)=?
Solution
Centripetal force=Spring Constant
as
Spring force = gravitational force
Answer:
B.) Greater than one
(at least I am pretty sure I am sorry if I am wrong I tried my best)
Explanation:
I think it is greater than one because it moves a short distance but it still is very helpful. The doorknob doesn't do much it just turns over and opens up a door. But, a doorknob CAN do much more. A doorknob can lock and keep things that you don't want inside out. It can also keep a door closed.
