1 electron has a mass of 9.1 X 10-31 kg. How many electrons n does it take to make 1 kg?
(1 e)/(9.1 X 10-31 kg) = n/(1 kg)
So, n = 1.10 X 1030 electrons
Each electron has a charge of 1.6 X 10-19 C, where C stands for Coulombs. So, the n electrons have a charge of q = ne = (1.10 X 1030 electrons) X (1.6 X 10-19 C/electron) = 1.76 X 1011 C.
Answer:
True.
Step-by-step explanation:
That is exactly what a perimeter is. Hope this helps
Step-by-step explanation:
Let base of triangle be x m.
Therefore, altitude =( x + 2)m
Therefore
Altitude = 10 m
Base = 8 m
That means she will start saving $44 a month instead of the $40 she was saving bafore
