Astronaut mark watney is very sick of potatoes. therefore, he throws a potato ata 30◦ angle above the horizontal as hard as he can. the initial height of the potatowhen it leaves his hand is 2.0 meters, and its initial velocity is 5.0 m/s (about 10 mph).gravitational acceleration on the surface of mars is 3.8 m/s2. how far will watneyhave to walk when he goes to retrieve the potato so he doesnt starve? (assume thatthe ground watney is standing on is flat and level.)

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.

Two models of the same compound are shown. in what way is model b better than model a? model b shows the types of elements in the compound, but model a does not. model b shows the three-dimensional shape of the molecule, but model a does not. model b shows how the atoms in the molecule are connected, but model a does not. model b shows the number of atoms of each element in the molecule, but model a does not
