1 A wellness exam is an overall general health assessment that may include blood tests, urinalysis, and parasite screening. 2  A wellness exam is recommended for most pets at least annually.
At the equator, the Earth's surface moves 40,000 kilometers in 24 hours. That is a speed of about 1040 miles/hr (1670 km/hr or 0.5 km/sec). This is calculated by dividing the circumference of the Earth at the equator (about 24,900 miles or 40,070 km) by the number of hours in a day (24). As you move toward either pole, this speed decreases to almost zero (since the circumference of the spinning circle at the extreme latitudes approaches zero).
Today we know that the circumference of the Earth is 24,901 miles. An easy way to remember is that the tangential velocity of Earth at the equator is about 1,000 miles per hour (this is why countries launch their rockets as close to the equator as possible and they always fly towards the east - the direction of rotation). A day takes 24 hours, so the Earth must be about 24,000 miles around.
