Explications étape par étape

A=15(10+2)

= 15 x 10 + 15 x 2

= 150 + 30

= 180C

B= 23(100-1)

= 23 x 100 + 23 x (-1)

=2300 - 21

= 2279

Atomic physicists usually ignore the effect of gravity within an atom. To see why, we may calculate and compare the magnitude of the ratio of the electrical force and gravitational force Fe Fg between an electron and a proton separated by a distance of 3 m. What is the magnitude of the electrical force? The Coulomb constant is 8.98755 × 109 N · m 2 /C 2 , the gravitational constant is 6.67259 × 10−11 m3 /kg · s 2 , the mass of a proton is 1.67262 × 10−27 kg, the mass of an electron is 9.10939 ×
