Rotation of the slotted bar oa is controlled by the lead screw that imparts a horizontal constant velocity v=1 m/s to collar c. pin p is attached to the collar. determine the angular velocity and acceleration of bar oa if x= 1 m, h = 1 m.

the correct choice is a .

do not post any more test or exam questions on

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
