PLS HELP ASAP I WILL GIVE BRAINLIEST I RLLY RLLY NEED THIS :( For a group project, a team of physics students is trying to develop a device that can launch
marbles so that they land in a predictable location every time.

17. The current version of the device applies a 1.81 Newton force to the marble at an angle
of 51° above horizontal. What are the horizontal and vertical components of this force
vector?

18. The students are not getting the marbles to travel as far as they would like. What are
some changes they could make to the device so that they get a greater range?

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
