Acharging rc circuit controls the intermittent windshield wipers in a car. the emf is 12.0 v. the wipers are triggered when the voltage across the 120 âµf capacitor reaches 10.0 v; then the capacitor is quickly discharged (through a much smaller resistor) and the cycle repeats. what resistance should be used in the charging circuit if the wipers are to operate once every 1.60 s?

While goofing off at the ice skating rink, a student takes off her shoes and places each of them on the ice. her friend, a hockey player, then shoots a hockey puck at each shoe. the first puck immediately comes to rest after it collides with the left shoe. the second puck rebounds after it collides with the right shoe. if each hockey puck has the same incoming speed, which shoe has greater speed after the collision? the right shoe. both shoes have the same speed. the left shoe.

Will give brainliest! jay rides his 2.0-kg skateboard. he is moving at speed 5.8 m/s when he pushes off the board and continues to move forward in the air at 5.4 m/s. the board now goes forward at 13 m/s. a. determine jay’s mass. b. determine the change in the internal energy of the system during this process.(express your answer to two significant figures and include the appropriate units.)
