Amachine has a mechanical advantage of 5. what force should be applied to the machine to make it apply 3000 n to an object?

--a--0.002 n
--b--600 n
--c--3000 n
--d--15,000 n

B. 600 Newtons

In our case, M.A = 5, and output force= 3000 N

Input force = Output force/Mechanical advantage

                  = 3000 N/ 5

                  = 600 Newtons

you and your brother should be dizygotic twins (fraternal) twins since identical twins can only be one gender: boy and boy   or   girl and girl.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
