Afuel gauge uses a capacitor to determine the height of the fuel in a tank. the effective dielectric constant keff changes from a value of 1 when the tank is empty to a value of k, the dielectric constant of the fuel, when the tank is full. the appropriate electronic circuitry can determine the effective dielectric constant of the combined air and fuel between the capacitor plates. each of the two rectangular plates has a width w and a length l (fig. p24.68). the height of the fuel between the plates is h

Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. the winds blow from west to east in jet streams but the flow often shifts to the north and south. jet streams follow the boundaries between hot and cold air. the earth's rotation is responsible for the jet stream as well.

Answer (d) valerie rides her bike south at 8 kilometers per hour///owen jogs south at 8 kilometers per hour ;

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 !
