If it takes the driver from the last question 0.2 seconds to slow down from 5m/s to 3m/s in her 1,000 kg car, how much force was applied to the car?

An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to move. 

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
