A 500 kg car is moving at 28 m/s. The driver sees a barrier ahead. If the car takes 95 m to come to rest, what is the magnitude of the average force necessary to stop?.

Six solutions are made, each with a y concentration of 1.0 μm and varying concentrations of ab as shown below. based on the concentrations, rank the solutions in decreasing order of reaction rate.

Two technicians are discussing a resistance measurement between the can-h and can-l wires. technician a says this measurement should be done with the ignition switch in the "run" position. technician b states that a measurement of 0 ohms indicates an open in the network. which technician is correct?
