Skateboarder, starting from rest, rolls down a 13.5 m ramp. when she arrives at the bottom of the ramp her speed is 7.37 m/s. if the ramp is inclined at 29.9 o with respect to the ground, what is the component of her acceleration that is parallel to the ground?

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?
