You are designing a rotor ride for an amusement park. What design will enable the rider to feel the greatest Fn (Normal Force)? a. Decrease the velocity of the ride and increase the radius
b. Decrease the velocity of the ride and decrease the radius
c. Increase the velocity of the ride and increase the radius
d. Increase the velocity of the ride and decrease the radius

d. Increase the velocity of the ride and decrease the radius

Explanation:

The normal force in the amusement park ride is produced by the centripetal force. The formula for this force is given as follows:

Fn = mv²/r

where,

m = mass of the body,

v = velocity of the body

r = radius of the path

Therefore, it is clear from the formula that force has a direct relation with the square of velocity and inverse relation with the radius of path. Hence, the design that will enable the rider to feel the greatest Fn will be:

d. Increase the velocity of the ride and decrease the radius

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
