Argon<span> gas is used in fluorescent and incandescent light </span>bulbs<span> to stop the oxygen in the light </span>bulbs<span> from corroding the hot tungsten filament.The use of </span>argon<span> in light</span>bulbs<span> prevents the evaporation of the tungsten filaments, which results in increased light </span>bulb<span> life.</span>
an object moves along a straight line, the distance travelled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving
Really long we’ll not long but far in distance
