The Jeep Patriot is a line of heavy-duty SUVs introduced by Chevrolet in 2007. For all models, change the vehicle's oil at least every 3,000 miles. The oil lubricates different parts of the engine that move, reducing friction and loss of power.
One factor which Galileo failed to consider is friction. All of the experiments were conducted in air and the factor of friction was thus present in all of them. This friction slowed down the pendulum's faster movements and led to a decrease in the length of the arc through which it passed.
Of course, Galileo points out that in fact nothing about the speed of light can be deduced from this observation, except that light moves faster than sound. He then goes on to suggest a possible way to measure the speed of light. The idea is to have two people far away from each other, with covered lanterns. One uncovers his lantern, then the other immediately uncovers his on seeing the light from the first.
