two resistors are to be combined to form an equivalent resistance of 1000 ohm. the resistance are taken from available stock on hand as acquired over the years. readily are two common resistors rated at 500+/_50 ohm and two common resistors rated at 2000 ohm+/_5%. what combination of resistors (series or parallel ) would provide the smaller uncertainity in an equivalent 1000 ohm resistance?

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
