Which diagram best illustrates the magnetic field of a bar magnet? A bar magnet with a north and south pole. Field line vectors are leaving the north pole and curl around to the south pole.
A bar magnet with a north and south pole. Field line vectors are leaving the south pole and curl around to the north pole.
A bar magnet with a north and south pole. Field line vectors are leaving the north pole and curl around to the south pole.
A bar magnet with a north and south pole. Field line vectors are leaving the south pole and curl around to the north pole. is a process that modifies light waves so they vibrate in a single plane.

Are there options for this?

The independent variable in this experiment is the angle at which the light from the ray box strikes the mirror.hope this .

Hellosubatomic particles  are  particles  that are smaller than the atom. protons, neutrons, and electrons are the three mainsubatomic particles  found in an atom. protons have a positive (+)  charge. an easy way to remember this is to remember that both neutron and no  electrical charge  start with the letter "n."have a nice day

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)
