A car is moving with speed 50 m/s and acceleration 4 m/s2 at a given instant. Using a second-degree Taylor polynomial, estimate how far the car moves in the next second. m Would it be reasonable to use this polynomial to estimate the distance traveled during the next minute

c. 195

explanation:

in the periodic table, platinum is the chemical element with atomic number 78. it means that it contains 78 protons in its nucleus, and 78 electrons in its orbitals.

there are several isotopes of the platinum, which determine its average mass number (and so its average atomic mass). the most abundant isotopes are:

platinum-194, platinum-195 and platinum-196, which have mass number of 194, 195 and 196, respectively.

considering all isotopes, the average mass number of platinum is 195, which means that on average platinum has 195 nucleons. since each nucleon has a mass of 1 u (1 atomic unit), the average atomic mass for platinum is 195.
