The best answer between the two options would be the second choice B) FALSE.
This shows that the length of a pendulum that makes one full swing in 2.2 seconds is 392.71 feet.
Given the formula for calculating the length of the pendulum expressed as:
where:
L is the length of the pendulum
T is the period of the pendulum
Given the following parameters:
Period T = 2.2 seconds
Substitute the given parameters into the formula will give;

So, this shows that the length of a pendulum that makes one full swing in 2.2 seconds is 392.71 feet.

Answer:
Explanation:
For a body on a ramp with mass m, the forces acting on the body along the vertical component are the weight and the normal reaction.
The weight of the body acts in the negative y direction while the normal reaction acts in the positive y direction
Taking the sum of forces along the y component
Sum Fy = -W+R = ma
Since acceleration is zero
-W+R = m(0)
-W+R = 0
-W = -R
W = R
Hence the Normal reaction force acting on the on the body is equal to normal force
