For problems that involve an object accelerating along an inclined plane, how can the weight be used to determine the force component that causes motion?
The weight is the full force that acts perpendicular to the surface of the ramp.
The weight times the cosine of the ramp's angle is the force perpendicular to the ramp.
The weight times the sine of the angle of the ramp acts down along the ramp.
The weight times the cosine of the angle of the ramp acts down along the ramp.

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
