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>

The transformer supplying power to an artist's light sculpture provides 9600-V AC when supplied by 120-V AC. If there are 100 tu
jarptica [38.1K]

Answer:

1.25 turns

Explanation:

From Transformer equation,

Ns/Np = Vs/Vp............................ Equation 1

Where Ns = Secondary turns, Np = Primary turns, Vs = secondary Voltage, Vp = Primary Voltage.

make Ns the subject of the equation  1

Ns = NpVs/Vp.......................... Equation 2

Given: Np = 100 turns, Vp = 120 V, Vs = 9600 V

Substitute into equation 2

Ns = 100(120)/9600

Ns = 1.25  turns.

Hence the are 1.25 turns in the  secondary coil = 1.25 turns

A motorcycle accelerated from 10 metre per second to 30 metre per second in 6 seconds. How far did it travel in this time ?
Ber [7]
U=10 m/s
v=30 m/s
t=6 sec

therefore, a=(v-u)/t
                   =(30-10)/6
                   =(10/3) ms^-2

now, displacement=ut+0.5*a*t^2
                              =60+ 0.5*(10/3)*36
                              =120 m
And you can solve it in another way:

v^2=u^2+2as
or, s=(v^2-u^2)/2a
       =(900-100)/6.6666666.......
       =120 m
