Question text The diameter of a hydrogen atom is about \(5\times10^{-11}\) meter. Suppose \(8.4\times10^8\) hydrogen atoms were arranged side by side in a straight line. Multiply these numbers to find the length of this line of atoms. What is the length in scientific notation?
Answers
Answer: 4.2 x 10⁻⁴m
Step-by-step explanation: Scientific Notation is a method of writing a very large or very small number. It consists in any real number between 1 and 10 multiplied by any power of 10 (positive or negative).
The diameter of hydrogen is 5x10⁻¹¹m. There are 8.4x10⁸ atoms of hydrogen.
To determine the length of the line of atoms, you could add the diameter the number of atoms or multiply the diameter by the number of atoms:
L = 5x10⁻¹¹ * 8.4x10⁸
As it is multiplication, you can mutiply the numbers and then add the power of 10, since they are in the same base:
L = 42 x 10⁻³m
or moving comma to the left:
L = 4.2 x 10⁻⁴m
The length of the line of hydrogen atoms, in scientific notation is 4.2x10⁻⁴m

You now have 332lbs. of food.
What percentage of your starting
amount do you have left?
Answers
Answer:
Basically you would have to follow the rule of proportions to answer this.
Step-by-step explanation:
x/100 = 332/550
Cross multiply: 332 x 100 = 550x
Then divide: 33200 / 550 = x
X = 60. 36 % or approximately 60%

FIRST TO ANSWER GET BRAINLIST OR WHATEVER ITS CALLED Which transformation will map quadrilateral ABCD onto itself?
OT(x, y) - (-x, -y)
OT(x,y) - (x,-y)
0 T(x, y) (y,x)
T(x,y) - (-y, x)
Answers
Answer:
Option (1)
Step-by-step explanation:
Since, quadrilateral ABCD shown on the graph is a parallelogram,
It will overlap itself when rotated by 180° about the origin.
In other words, all vertices of the given parallelogram will overlap itself when they are rotated by 180° about the origin.
Rule for the rotation of a point about the origin is,
(x, y) → (-x, -y)
Therefore, Option (1) will be the answer.
