Trees are part of the biosphere. They need water to survive. They take in water from the soil through their roots and release wa
dolphi86 [110]

Answer:

Explanation:

The hydrosphere represents the total amount of water on earth. Soil water is part of the hydrosphere.

The lithosphere represents the varieties of rocks present on the planet, including their weathered part which is the soil.

The atmosphere represents the different gas layers surrounding the earth.

The biosphere represents the portion of the earth that supports life.

<em>When soil water moves into the tree through the roots of the tree, the hydrosphere, the lithosphere and the biosphere are interacting all together. When the some of the water taken in is released to the atmosphere as vapor through evapotranspiration, it represents an interaction with the atmosphere.</em>

Calculate the acceleration of a bus whose speed changes from 7 m/s to 16 m/s over a period of 5 s.
Bezzdna [24]
Let’s do this together!

Okay so the acceleration formula is vf-vi over time .

So the initial velocity (vi) 7m/s final velocity (vf) is 16m/s so we’re going to subtract 16-7 which is 9
M/s

So the time is 5s so 9m/s divided into 5s is 1.8m/s/2

So the answer is 1.8m\s2

Question 20
fenix001 [56]

Answer:

  (b)  Water

Explanation:

The density of the liquid is found by dividing its mass by its volume.

__

<h3>mass</h3>

The mass of the liquid is the difference in mass between the full and empty graduated cylinder:

  liquid mass = (145 g) -(45 g) = 100 g

<h3>volume</h3>

The cylinder is said to contain 100 mL of the liquid, so that is the volume of interest.

<h3>density</h3>

The ratio of mass to volume is the liquid's density:

  ρ = (100 g)/(100 mL) = 1 g/mL

This density identifies the most likely liquid as water.

How do silicate materials form
Alisiya [41]
Silicates that are composed of infinite chains of tetrahedrons are called inosilicates; single chains have a unit composition of SiO 3 or Si 2 O 6, whereas double chains contain a silicon to oxygen ratio of 4:11. Phyllosilicates, or sheet silicates, are formed when three oxygen atoms are shared with adjoining tetrahedrons.

How is high temperature achieved by concave mirror?
tensa zangetsu [6.8K]

A concave mirror is used in the design of solar furnaces because they converge the parallel sunrays at a point. This helps to increase the temperature of the furnace.
