Answer:
2.62 years
Explanation:
The half life of a material is the time taken for half of the number of radioactive atoms in a radioactive material to remain.
If a radioactive material is cut into pieces, each piece has the same half life as the whole material.
Hence, if Strontium-147 is cut into pieces, each piece will have a half life of 2.62 years, just as the whole material.
The statement that your dog may live in "un immeuble residentiel" if you lived in a French city is false.
Answer:
Two measures that have been introduced by the US and local governments to reduce the consumption of gas are the introduction of light-rail and the use of carpool lanes.
Explanation:
The introduction of light-rail will reduce the consumption of gas from personal vehicles and also reduce personal vehicle carbon emissions. One example is the Dallas Area Rapid Transit (DART) and Los Angeles has a system that combines light rail and heavy rail called Metro Rail. The use of carpool lanes will reduce the use of gas and help to reduce traffic congestion because there will be less cars on the road in high traffic areas where there is a large percentage of the population who commutes to and from work on freeways. Carpool lanes or High Capacity Vehicle (HCV) lanes are found in metropolitan areas like Washington DC.
