A 1447 kg car accelerates from a complete stop at a traffic light to a speed of 28.5 m/s in 73 seconds (the car is on a perfectly flat surface). The ground exerts a horizontal force on the tires preventing them from slipping as the car accelerates. What is the average of this force for the entire experiment

What is the potential energy of a 30kg rock that falls 15 meters

elctricity and magnet is conversion to it

2. Expert says:

Answer(a)   the matererials that are in contact, the two materials and the nature of their surfaces/// (b)/// the force pushing the two surfaces together, pushing the surfaces together causes the more of the asperities to come together and increases the surface area in contact with each other

If one were to put the y value into the equation, they could find out what x is for a certain value of y.  putting in the value of y (1), we get the equation: 1=4x-12=4xx=0.5this means that the value of x when why is 1 is x=0.5
