A boy wants to lift a 100 N rock using a stick lever and stone fulcrum. If the rock is 0.5 m from the fulcrum and the boy can exert 50 N of force, how far from the fulcrum must he push? Hint: Use the Law of Torques equation. Fe x le = Fr x lr

Assume this car is driven off a cliff . how many arrows of force need to be drawn in the free body diagram? assume no air resistance -five -one -three -four

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?

What organization and environment is described above?
