Answer:

The number of turns is 2.2 \times 10^{3}

Explanation:

The computation of the number of turns is shown below:

B = \mu o \frac{N}{L}I \\\\N = \frac{BL}{\mu oI}\\\\= \frac{0.030 T \times 0.42}{4\pi\times 10^{-7} (4.5)} \\\\= 2.2 \times 10^{3}

hence, the number of turns is 2.2 \times 10^{3}

A flow is isentropically expanded to supersonic speeds in a convergent-divergent nozzle. The reservoir and exit pressures are 1.
Kamila [148]

Answer:

Ae/A* = 1.115

Explanation:

Let the reservoir pressure be  p_0

Let the exit  pressure be p_e

Ratio of reservoir pressure and exit pressure

\frac{p_o}{p_e} = \frac{1}{0.3143}

  = 3.182

For the above value of pressure ratio

Obtain the area ratio from the isentropic flow table

Ae/A* = 1.115

The value of pressure ratio is Ae/A* = 1.115

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>

Three 10-cm-long rods form an equilateral triangle. Two of the rods are charged to + 19 nC, the third to - 19 nC.What is the ele
Sveta_85 [38]
<span>We calculate the electric field as follows:
r = </span>√<span>(3)/6 x 19 cm = .05484 m 
The angle for the triangle would be 30 on each side.
tan(30) = r/(L/2) 

E' = kQ/{r*sqrt[(L/2)^2 + r^2]} = (8.99e9 x 15e-9) / {.05484 * sqrt[(.19/2)^2 + .003]}
</span>E' <span>= 22413 N/C
The value above is the electric field strength for a single rod at the center. 

|E'| = 22413 N/C 
E = 2|E'|sin(30) + |E'| = 49000 N/C</span>
