The total charge a battery can supply is rated in ma⋅h , the product of the current (in ma ) and the time (in h ) that the battery can provide this current. a battery rated at 1000 ma⋅hr can supply a current of 1000 ma for 1.0 h , 500 ma current for 2.0 h , and so on. a typical aa rechargeable battery has a voltage of 1.2 v and a rating of 1800 ma⋅h . part a for how long could this battery drive current through a long, thin wire of resistance 34 ω ? express your answer in hours. δt δ t = nothing h submitrequest answer provide feedback next

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
