What could you do to change the volume of a gas?

Answers

Answer 1

Answer: People are going to tell you about heating or cooling the gas, but
there's only one way to change the volume of a gas: Put it into a
different container !

A gas always expands to fill whatever you keep it in ... doesn't matter
how warm or cold it is. So the only way to make it change its volume
is to put it into a larger or smaller jar.

Answer 2

Answer: Heat it up to make it expand, or cool it down to make it contract. When you heat a gas, the particles of the gas get farther apart, therefore making the gas expand. The opposite happens when you make it colder.

Id say B, only because atoms are everywhere.

A. the force of attraction between two objects

Because gravity is a universal law.

reflecting, spherical Christmas tree ornament has a diameter of 9.0 cm. A child looks at the ornament from a distance of 12 cm. Describe the image she sees.

Answers

The distance of the image observed by th girl is 2.77 cm.

Focal length of the lens

The focal length of the lens is calculated as follows;

F = R/2

where;

R is the radius of lens

R = 9 cm/2 = 4.5 cm

F = R/2

F = 4.5/2

F = 2.25 cm

Image distance

The distance of the image observed by th girl is caculated as follows;

1/f = 1/v + 1/u

1/v = 1/f - 1/u

1/v = 1/2.25 - 1/12

1/v = 0.3611

v = 2.77 cm

Thus, the distance of the image observed by th girl is 2.77 cm.

f = R/2

(9/2)/2 = 2.25 cm

i = 1/(1/f - 1/o)

1/(1/2.25 - 1/12) = 1/2.769 ⇒ 0.36

I believe the image would appear upright.

What is the total displacement of a bee that flies 2 meters east, 5 meters north, and 3 meters east? explain how you did it

Answers

The displacement covered by the bee that flies 2 meters east, 3 meters east, and 5 meters north is 7.05 meters.

What is Displacement?

Displacement of an object can be defined as the actual change in the position of an object. It is a vector quantity because it has both the direction and the magnitude.

The bee travels 2 meter east and 3 meters east. Therefore, the total distance covered in the east direction is (2+3) meters = 5 meters.

The bee travels 5 meters in the north direction. This makes a square of 5 meters dimension and in this condition, the displacement covered by the bee will be the diagonal of the square. Therefore, the total displacement of the bee can be calculated as:

Diagonal of square = $√(2)$ a

where, a = side of the square

Side of the square = 5 meters

Diagonal of the square = $√(2)$ × 5

$√(2)$ = 1.41

Therefore, diagonal = 1.41 × 5

Displacement of the bee = 7.05 meters

It flies 2+3meters east and 5 meters north so it flies 5 east and 5 north. Then the way of it would be diagonal of 5x5 square it equals 5√2 which is 7.07.
