When the students arrive at the competition, it is determined that the height of the
sphere launcher can no longer be adjusted due to a mechanical malfunction.
Therefore, the spheres must be launched at a vertical position of y = 1
However, the spheres may be launched at speed voor 2V0.
In a clear, coherent paragraph-length response that may also contain diagrams
and/or equations, describe the speed at which a sphere should be launched so that
the students earn the maximum number of points in the competition.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
