a student builds a simple circuit with a single resistor with resistance R and measures an electric potential difference across the resistor .Then the student replaces the resistor with a new one of resistance 2R and keeps the electric potential difference the same .what is the current status through the new circuit in terms of the original current​

22. the top of a cliff is located a distance h above the ground. at a distance h/2 there is a branch that juts out from the side of the cliff, and on this branch a bird's nest is located. two children throw stones at the nest with the same initial speed, one stone straight downward from the top of the cliff and the other stone straight upward from the ground. in the absence of air resistance, which stone hits the nest in the least amount of time?
