Acat plays with a toy mouse suspended from a light string of length 1.25 m, rapidly battling the mouse so that it acquires a speed of 2.75 m/s while the string is still vertical. use energy conservation to find the mouse's maximum height above its original position

The charge on a charged sphere is: a)concentrated at its centerb)distributed uniformly throughout its volumec)clustered on its centerd)distributed uniformly over its surface

How is zig zagging a form of acceleration?

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.
