The simple machines below both lift an object with a weight of 200N. The both lift the load 2 m off the ground. Select all that are true about the pulleys below. -The work done for both simple machines is 1200 J.
-The effort force for both pulleys are the same because the work is the same.
-The effort force for the first pulley is 100N and the effort force for the second pulley is 66.67 N.
-The mechanical advantage for both pulleys are the same.
-The work done for the first pulley is less because it has a lower mechanical advantage.
-The work done for both simple machines is 400 J

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.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
