Two objects are traveling on the same track. For 10 s, Object X has an average acceleration of 2.0 m/s / s . If Object Y has an initial velocity of 0 m/s and a final velocity of 35 m/s after 10 s, how does its acceleration compare to Object X's?

Anybody wanna ? (picture included? )

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.

If element x has 99 protons how many electrons does it have
