What is the independent variable and dependent varaible of "A student lab group performed an experiment with different batteries to determine the effect of the voltage of a battery upon the current in a simple electrical circuit. They put a 1-Volt battery and measured the current in the circuit to be 0.25Amps. They replaced the 1-Volt battery with a 2-Volt battery and measured the current to be 0.56Amps. They continued increasing the voltage and measuring the current. 3-Volts resulted in a current of 0.74Amps. 4 Volts resulted in a current of 1.02Amps. At 5 Volts, they measured a current of 1.26 Amps."

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 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. a) what is the block's initial mechanical energy? 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.
