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>

Compare the atmospheric pressure of two places 500m and 2 km respectively above sea-level. Give reason for your answer.
Lera25 [3.4K]

Answer:

Explanation:

The average pressure at mean sea-level (MSL) in the International Standard Atmosphere (ISA) is 1013.25 hPa, or 1 atmosphere (atm), or 29.92 inches of mercury. Pressure (p), mass (m), and the acceleration due to gravity (g), are related by P = F/A = (m*g)/A, where A is surface area.

A long wire is known to have a radius greater than 4.0 mm and to carry a current uniformly distributed over its cross section. i
ollegr [7]

Magnetic field outside it due to long wire is given by

B = \frac{u_o i}{2 \pi r}

Magnetic field due to long wire inside wire at any point

B = \frac{u_o i r}{2 \pi R^2}

Now the ratio of two magnetic field is given by

\frac{B_{in}}{B_{out}} = \frac{r_1/R^2}{1/r_2}

\frac{0.285}{0.200} = \frac{4*10}{R^2}

1.425 = \frac{40}{R^2}

R = 5.3 mm
