In order to prevent muscle contraction from mis- aligning bones during healing, broken legs must be

supported horizontally and kept under tension

(traction) directed along the leg. If the leg weighs

1,008 N, what traction force does this hanging weight

produce upon the leg ? The supporting wires make an

angle of 30 degrees with respect to the floor.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

newton's first law of motion

real, smaller and upside-down.   so the answer should be b.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
