The boy applying the input force moves so that he is 1.5m from the fulcrum. the seesaw applies an output force to the other boy who is 2m from the fulcrum. what is the new ideal mechanical advantage?

Mechanical advantage is defined as the ratio of output force and input force

so we can say it is

now here we know that on a see saw torque is balanced

so we can say

so here it is given as

so here we can say

so mechanical advantage will be 0.75

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
