Signs of Lyme disease include skin rash and painful inflammation of joints (particularly the knees), accompanied by flu-like symptoms. The symptoms of Lyme disease increase in severity as the disease spreads though the body. Early diagnosis and treatment are important to stop the progression of the disease. If untreated, the disease can result in neurological disorders such as peripheral neuropathy, including Bellâs palsy, as well as pain, numbness or weakness in the limbs.

In this case, the terminal velocity increases to about 320 km/h (200 mph or 89 m/s), which is also the maximum speed of the peregrine falcon diving down on its prey. An object falling will fall 9.81 meters per second faster every second (9.81 m/sÂ²). The reason an object reaches a terminal velocity is that the drag force resisting motion is directly proportional to the square of its speed. At low speeds the drag is much less than the gravitational force and so the object accelerates.
