Electrons flow from the negative terimal of a
battery to the positive terminal. conventional flow
assumes that current flows
a out of the negative terminal, through the circuit
and into the positive terminal of the battery.
b out of the positive terminal, through the circuit!
and into the negative terminal of the battery.
c out of the positive terminal, goes into the first
resistor, changes direction, and goes back into
the positive terminal of the battery.
d. out of the negative terminal, goes into the first
resistor, changes direction, and goes back into
the negative terminal of the battery.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

Simple machines can a. increase force only b. decrease force only c. increase or decrease force
