Calculate the pressure (in pascals and atmospheres) exerted by a mass of 1.0 kg pressing through the point of a pin of area 1.0 x 10-2 mrrr' at the surface of the Earth. Hint. The force exerted by a mass m due to gravity at the surface of the Earth is mg, where g is the acceleration of free fall (see endpaper 2 for its standard value).
It's not until death that the percentage of carbon-14 will begin to diminish from decay. Because radioactive decay is a first-order process, the integrated rate law for a first-order reaction can be rewritten asfraction remaining
