Afriend talks to you as she walks past you at a speed of 2.25 m/s. why do you not notice a doppler shift in her voice as she passes?

What happens to atoms and chemical bonds during a reaction?

The force will determine the 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.
