A 0.20-kg baseball is moving at 26.9 m/s when it is hit by a bat, causing it to reverse direction and have a speed of 37.6 m/s. If the event takes 0.05 s, the average force experienced by the ball is N.

Acertain half-reaction has a standard reduction potential e_red^0 = -0.94 v. an engineer proposes using this half-reaction at the cathode of a galvanic cell that e must provide at least 1.00 v of electrical power. the cell will operate under standard conditions. a. is there a minimum standard reduction potential that the half-reaction used at the anode of this cell can have? b. is there a maximum standard reduction potential that the half-reaction used at the anode of this cell can have?
