Johnny lets a 0.5kg ball roll on the floor of the classroom. The ball gradually slows down. The coefficient of friction between the floor and the ball is 0.18. Draw a free body diagram and calculate the acceleration of the ball.

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 !

Iwould think it is temperature, silica, oxides (gases)
