You are driving at a reasonable constant velocity in a van with a windshield tilted 120o relative tothe horizontal. as you pass under a utility worker fixing a power line, the worker’s wallet fallsonto the windshield. determine the acceleration needed by the van so that the wallet stays inplace if frictional forces are negligible.

Ais the answer hope this

Amicroscope, because these cells are so small that you would not be able to see them, or what they attack without it.

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 !
