Answer:

D. stratosphere

Explanation:

The atmosphere is formed by five layers: The troposphere, stratosphere, mesosphere, thermosphere and exosphere.

The troposphere is the lowest layer of the Earth's atmosphere. We live in the troposphere. Most clouds are in the troposphere.

The layer following the troposphere is the stratosphere in this layer is the so-called ozone layer and in it all meteorological phenomena that influence living beings, such as winds, rain and snow occur. In addition, it concentrates most of the oxygen and water vapor.

One mole of an unknown sample contains 120 g of carbon and 30.3 g of

barxatty [35]

atomic mass of carbon is C = 12 g/mol

atomic mass of hydrogen is H = 1 g/mol

now number of carbon atoms

$N_c = \frac{120}{12} = 10$

Similarly the number of hydrogen atoms are

$N_H = \frac{30.3}{1} = 30$

so Carbon atom and hydrogen atom must be in ratio of 10:30

so the ratio is 1:3

now the empirical formula is always in simplest form

Velocity answer. please explain steps

spin [16.1K]

As it is a position time graph

So, it's slope represents velocity

During last 15 seconds

it passes through (5,17) (20,2)

Slope = -15/15 = -1

So Velocity= -1 m/s

What class of solids is made up of regularly repeating subunits of tightly packed, orderly arrangements of atoms, ions, or molec

xxTIMURxx [149]

The answer is crystalline solid. Crystalline solids have a regular arrangement of particles, because of that, they possess definite geometry.
This means that if you take a look at the crystal under the microscope you would notice that there is a pattern that constantly repeats. This pattern is called a unit cell, and crystal is made up of stacked unit cells.

Henrietta is going off to her physics class, jogging down the sidewalk at a speed of 4.15 m/sm/s. Her husband Bruce suddenly rea

Darya [45]

Answer:

Explanation:

Distance travelled by Henrietta in 5.5 s = 4.15 x 5.5 = 22.825 m .

Time taken by lunch of bagels to fall vertically by 55.2 m . Let it be t .

s = ut + 1/2 g t²

55.2 = 0 + .5 x 9.8 x t²

t² = 11.26

t = 3.356 s

By the time the lunch of bagels touches the hand of Henrietta , she would have travelled further by distance

s = 3.356 x 4.15 = 13.9 m

She is now at distance of 22.825 + 13.9 = 36.725 m from window .

So lunch of bagels must travel a horizontal distance of 36.725 m in 3.356 s which the time of fall of bagel .

Speed of bagel = distance / time

= 36.725 / 3.356

= 10.94 m /s

b )

Henrietta is 36.725 m from window at the time when she catches the bangel.
