Carbon-14 has a half-life of 5,730 years. if the age of an object older than 50,000 years cannot be determined by radiocarbon dating, then * carbon-14 levels in a sample are undetectable after approximately ten half-lives. * carbon-14 levels in a sample are undetectable after approximately nine half-lives. * the half-life of carbon-14 is too long to accurately date the object. * a radioisotope with a shorter half-life should be used to date the object.

Acompany manufactures large valves, packed in boxes. a shipment consists of 1500 valves packed in 75 boxes. each box has the outer dimensions 1.2 x 0.8 x 1.6 m and the inner dimensions 1.19 x 0.79 x 1.59 m. the boxes are loaded on a vehicle (truck + trailer). the available capacity in the vehicle combination is 140 m3. each valve has a volume of 0.06 m3. - calculate the load factor on the box level (%). - calculate the load factor on the vehicle level (%). - calculate the overall load factor (%).
