Ответ:

Кожен електрон має елементарний заряд, який дорівнює приблизно 1,6·10^(-19) Кл. Тому, кількість заряду, який перейшов з тіла А на тіло В, можна визначити наступним чином:

Q = ne,

де Q - заряд, який перейшов з тіла А на тіло В, n - кількість електронів, які перейшли, а e - елементарний заряд.

Підставляючи дані в формулу, отримуємо:

Q = (30·10^(13))·(1,6·10^(-19)) Кл ≈ 4,8·10^(-5) Кл.

Таким чином, тіло А має заряд -4,8·10^(-5) Кл.

Reading Task 1. Read the text about Kenneth.
Mark the sentences TRUE or FALSE according to the context. My dream job
My dream job would be becoming a professional baseball player. I grew up playing little league baseball. I was never the best player on the team; yet, playing baseball was something I would look forward to doing every day and just have fun doing it. I haven’t played baseball for the last four years. I really miss the times when I would just have that happy feeling when my dad would drive up to the park, when I would get a base hit, when I would catch a fly ball, or just the fact that I was a part of a team. So many baseball players these days take their jobs for granted. Many play baseball not just because they are good at it, but because of the money. Alex Rodriguez signed a $252 million contract for the Texas Rangers in 2000. Anybody in the entire world would love to be in his shoes. After all, what would you do with $252 million? For myself, I would love to be in Alex Rodriguez’s shoes, not because of the money, not because of the fame, but because if I were in his shoes, I would just treasure every moment of every second that I am on the field. I would feel like the luckiest person alive every time I am reminded that I am living the dream, a dream that many people like myself would die to get the chance to do. 50
