Answer:
11/4 1/10/3/4 -/-3
Step-by-step explanation:
This is an iteration method for finding the square root.
The ? is also your first initial guess.
? = 10.5
The iteration formula for the square root is actually.
√n = (x + n/x)÷2.
Where x is your guess.
Answer:
33
Step-by-step explanation:
What you do is you take 57 and since it is a right triangle you take 90 and add them together. You will get 147. You will then minus this from 180 to get 33.
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.
