How do I find the answers

Your answer would be, the due process clause of the 14th., and 5th. amendments differ the clause in the 14th. amendment has been interpreted, to mean that state government must provide some of the protections within the bill of rights.your answer would be, the clause in the 5th. amendment was specifically written to restrict a new powerful government.hope that !

Iwould think it would be efficiency.

The figure is missing but we can answer anyway.the correct answer is "releasing the string". in fact, when the person is holding the bow and the arrow, the kinetic energy of the arrow is still zero (because the arrow is not moving). the moment the arrow is released, it acquires a velocity v, so its kinetic energy will become different from zero: where m is the mass of the arrow and v its velocity.  all the other options, instead, do not increase the kinetic energy of the system: -  pulling farther back on the string : this will just increase the elastic potential energy of the system-  holding the arrow higher: this will increase the gravitational potential energy of the system (which is given by u=mgh, where h is the height above the ground)-  decreasing the mass of the arrow: this will decrease the gravitational potential energy of the system (which is given by u=mgh, where m is the mass)
