The electric flux density produced inside a parallel plate capacitor with a 3 cm diameter and plate separation of 60mm .5 cos(20π×103t) az c. use ampere's law in point form to determine the following a. the curl of the magnetic field intensity due to displacement current produced in the capacitor. plot the magnitude of the curl of the magnetic field intensity versus the magnitude of the electric flux density produced b. in the capacitor for s ts 10 msec.

Is there a picture to go along with this

Newton's first law describes something special that results from the sum of all the external forces (including gravity) on an object. 

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)
