I believe the scientific notation would be 1.8× 10^1
Scientific notation is a way of expressing numbers that are too big or too small to be conviniently written in decimal form.
For example, a number like 0.0000000005 is written as 5 ×10^10

Examine the image of a potassium atom. (Image is below)

Bess [88]

Answer:

The answer to your question is D.

Explanation:

Potassium has 4 energy levels in the first level (A) has only 2 electrons,

in the second energy (B) level has 8 electrons, in the third energy level (C) also has 8 electrons and in the fourth energy level has only one electron.

Valence electrons are located in the outermost shell so Potassium has only one electron located in the shell D.

Students in physics class are asked to find the relationship between the length of a pendulum (string with a weight at the botto

Goshia [24]

Answer:

1) $Time \ for \ pendulum \ swing \ left \ and \ right = 2 \times \pi \times \sqrt{\dfrac{Length \ of \ the \ pendulum \ string}{g} }$

2) The dependent variable = The time it takes for one pendulum swing

3) The independent variable = The length of the pendulum string with weight at the bottom

Explanation:

The relationship between the length of the pendulum string and the time it takes for one pendulum swing is giving as follows;

$T = 2 \cdot \pi \cdot \sqrt{\dfrac{L}{g} }$

Where;

T = The period of oscillation = The time to complete one oscillation =Two swings of the pendulum

L = The length of the pendulum

g = The acceleration due to gravity

Therefore, the time it takes for one pendulum swing is directly proportional to the square root of the length of the pendulum

The dependent variable = The time it takes for one pendulum swing

Th independent variable = The length of the pendulum string with weight at the bottom.
