POCT in the ED â¢ Faster does not always lead to better outcome â¢ Lab tests are rarely the rate limiting factor in ED disposition â¢ Process analysis is the key understanding and improving patient throughput in the ED â¢ Test menu selection is a critical component of the potential application of POCT â¢ Match available tests to disposition decisions
Gravity decreases with altitude as one rises above the Earth's surface because greater altitude means greater distance from the Earth's centre. All other things being equal, an increase in altitude from sea level to 9,000 metres (30,000 ft) causes a weight decrease of about 0.29%.
If the planet changes its distance from the Sun as it orbits, then the force of gravity between them must change. If the force that the Sun exerts on the planet increases (as the planet moves closer), then the acceleration of the planet must increase, resulting in a higher orbital speed, and vice versa.fter deriving gravitational orbital motion from the laws of motion, law of gravity and quite a bit of calculus, Newton found that Kepler's 3rd Law should actually be this: p 2 (yrs) = a 3 (AU) / (M 1 + M 2); where the masses are measured in units of our Sun's mass.
