The half-life of Carbon-14 is 5700 years. After 17,000 years, there are 7 g of 14C remaining in a fossil. Approximately how many grams of 14C were in the fossil initially?

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

b.false that your answer
