What best describes an impulse acting on an object? the net force on an object divided by the time of impact
the velocity of an object divided by its mass
the product of an object's mass and the time of force impact
the product of an object's mass and its change in velocity

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?
