What is an atom? and what is the difference of atom and molecule

Anettt [7]

Answer: An atom is the basic unit of matter and the defining structure of elements. The difference between an atom and a molecule is that molecules are formed when two or more atoms bond together. If molecules contain atoms of different elements, that substance is known as a compound. Atoms make up molecules.

Hurry please!!! Fast response

AlladinOne [14]

Answer:

$SA= \frac{2}{3} \pi rl+16 \pi r^2$

Step-by-step explanation:

Surface area of the original cone

$SA= \pi r l + \pi r^2... (1)$

When, radius is quadrupled and slant height is reduced to one sixth

$i. e. \: \:r = 4r\: \: \&\:\: l= \frac{1}{6}l$

Plug the above values of r and $l$ in equation (1), new surface area becomes:

$SA= \pi (4r)\times \frac{1}{6} l+ \pi (4r)^2$

$SA= \frac{4}{6} \pi rl+16 \pi r^2$

$\huge \purple {\boxed {SA= \frac{2}{3} \pi rl+16 \pi r^2}}$

Find the perimeter of the shape. (Answer choice In pic)

Lana71 [14]

Answer: 49.2 cm

Explanation: I don’t know how to explain it without a visual so I hope you end up figuring it out! All I can say is: use Pythagorean’s theorem for that triangle to the left (if you know what I mean) to find the hypotenuse and then add all the sides up!

Have a great day!

Use the recursive relationship to complete the next two rows of Pascal's triangle. Row 5: 1 _ _ _ _ 1 Row 6: 1 _ _ _ _ _ 1

frosja888 [35]

Answer:

1 5 10 10 5 1 Row 5

1 6 15 20 15 6 1 Row 6

Recursive relationship:

Each row has number of positions = row number + 1. The Row 0 is always 1.

The first and last number in each row is 1, the number in the second position and the penultimate corresponds to the number of the row. The middle numbers correspond to the sum of the two numbers in the top row. The resulting number from the addition is located in the middle of the numbers added in the next row.

Step-by-step explanation:

The pascal's triangle

* Row 0 = 1

* Row 1 = 1 1

1 Row 0

1 1 Row 1

Since there are only two positions, the first and last are 1.

*Row 2 = 1 _ 1

1 Row 0

1 1 Row 1

1 2 1 Row 2

2 is the sum of 1 + 1 and we place it in the next row between the added numbers 1 and 1.

* Row 3 = 1 _ _ 1

1 Row 0

1 1 Row 1

1 2 1 Row 2

1 3 3 1 Row 3

1 + 2 = 3 (the row number and the and adding the numbers from the previous row)

* Row 4 = 1 _ _ _ 1

1 Row 0

1 1 Row 1

1 2 1 Row 2

1 3 3 1 Row 3

1 4 6 4 1 Row 4

1 + 3 = 4 (the row number)

3 +3 = 6

* Row 5 = 1 _ _ _ _ 1

1 Row 0

1 1 Row 1

1 2 1 Row 2

1 3 3 1 Row 3

1 4 6 4 1 Row 4

1 5 10 10 5 1 Row 5

1 + 4 = 5

4 + 6 = 10

* Row 6 = 1 _ _ _ _ _ 1

1 Row 0

1 1 Row 1

1 2 1 Row 2

1 3 3 1 Row 3

1 4 6 4 1 Row 4

1 5 10 10 5 1 Row 5

1 6 15 20 15 6 1 Row 6

1 + 5 = 6

5 + 10 = 15

10 + 10 = 20
