Part a Place the ramps on the floor and time each ramp for time it takes for wooden block too reach thee floor. The times will be different and thus you can conclude that friction will increase the time Part b Caleb uses the same block as this is his control variable that he wants to keep same so that the results are correct and accurate Part c The independent variable is the thing you change before you test so it will be the surface on which the wooden block is sliding The dependent variable is the variable you measure so that will be the time it takes for the block to slide to the bottom.
DE which is the differential equation represents the LRC series circuit where L d²q/dt² + Rdq/dt +I/Cq = E(t) = 150V. Initial condition is q(t) = 0 and i(0) =0. To find the charge q(t) by using Laplace transformation by Substituting known values for DE L×d²q/dt² +20 ×dq/dt + 1/0.005× q = 150 d²q/dt² +20dq/dt + 200q =150
