Please help if can (>^ <)ゞ The Pioneer 10 space probe was launched in 1972 to explore the asteroid belt and Jupher. The probe continued traveling way from the Solar System and into deep space in 2003, when it was over seven billion miles from home, is power supply failed und a
contact was lost Just before the power falure, data from the spacecraft indicated a reduction in its velocity that was too rapid to be explained by the Sun's rational pull alone. Which of the following is the best scientific conduion based on the unexpected data?

A-The spacecraft was slowed by a force other than gravity

B-The instruments measuring Pioneer 10's velocity malfunctioned

C- The law of universal gravitation is incorrect and should be revised

D-The data collected regarding the Sun's gravitational force is incorrect

The answer is B the instrument measuring pioneer 10’s velocity malfunctioned

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
