an unmarked battery has unknown internal resistance if the battery is connected to a fresh 5.60 volt battery positive to positive and negative to negative the current through the circuit is 10.0ma if the polarity of the unknown battery is reversed the current increase to 250ma determine the source voltage and internal resistance of the unknown battery assume that in each case the direction of the current is negative to positive in the 5.60v battery

Well the magnitude of its acceleration related to that car starts with the oil change like when you have to change the oil in your car you have to make sure that your precious car is starting really propley and very well

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
