Clear the circuit diagram and make a new circuit. Set the voltage of the battery to 9 V, set up a series circuit with three resistors. Set one resistor to 10 Ohms, the second resistor to 21 Ohms, and the third resistor to 13 Ohms. What is the equivalent resistance? What is the average current across the circuit?

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?

In a good thermo flask the main cause of heat loss is

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)
