The driver of a car moving at 90.0 km/h presses down on the brake as the car enters a circular curve of radius 195.0 m. If the s
peed of the car is decreasing at a rate of 4.0 km/h each second, what is the magnitude of the acceleration of the car (in m/s2) at the instant its speed is 58.0 km/h?
Concentration involves the relative amounts of solvent and solute in a solution, when strength is related to the extent to which a substance dissociates :)) i hope this is helpful have a nice day
