In a fusion reactor, the high temperature of the order of 108 k is required in order that what condition is met?

1 answer:

4 0

In order for a fusion reactor to function well, one of the important conditions to be met is a high temperature at 108 million Kelvin. This is six times hotter than the temperature of the sun's core. At this temperature, the element hydrogen's state is a plasma, not a gas, where the atoms are stripped of electrons and thus can move freely. This is an ideal condition to enable the reactor to function where it enables the hydrogen atoms to gather enough energy for the reaction which will occur in the later stages of the process. <span />

A 150kg person stands on a compression spring with spring constant 10, 000 N/m and norminal.Length of 0.50.What is the togal len

Eva8 [605]

Answer:

Total length of spring 0.647 m

Explanation:

We have given mass of the person m = 150 kg

Acceleration due to gravity $g=9.8m/sec^2$

Spring constant k = 10000 N/m

Nominal length of spring = 0.50

According to hook's law

$mg=kx$

$150\times 9.8=10000\times x$

x = 0.147 m

So total length of spring = 0.50+0.147 = 0.647 m

calculate the weight of an object of mass 100kg on the surface of a planet whose mass is 4.8×10^24 kg and diameter is 12000km.

notsponge [240]

Answer:

p= mv

where p is momentum

m is mass

v is velocity

so it's given p= 100kgm/sec

v= 4m/s

so putting in the formula

100= m × 4

m = 25kg

The maximum stress in a section of a circular tube subject to a torque is τmax = 27 MPa . If the inner diameter is Di = 3.75 cm

DIA [1.3K]

Answer:

$T_{max} = 4.735\,kN\cdot m$

Explanation:

The shear stress due to torque can be calculed by using the following model:

$\tau_{max} = \frac{T_{max}\cdot r_{ext}}{J_{tube}}$

The maximum torque on the section is:

$T_{max} = \frac{\tau_{max}\cdot J_{tube}}{r_{ext}}$

The Torsion Constant for the circular tube is:

$J_{tube} = \frac{\pi}{32}\cdot (D_{ext}^{4}-D_{int}^{4})$

$J_{tube} = \frac{\pi}{4}\cdot [(0.053\,m)^{4}-(0.038\,m)^{4}]$

$J_{tube} = 4.560\times 10^{-6}\,m^{4}$

Now, the require output is computed:

$T_{max} = \frac{(27\times 10^{3}\,kPa)\cdot (4.560\times 10^{-6}\,m^{4})}{0.026\,m}$

$T_{max} = 4.735\,kN\cdot m$

Who pays the income tax, the payroll tax, the estate and gift taxes? Who bears the burden of the gasoline and tobacco taxes? If Congress were to raise this tax rate, or lower that tax deduction, who would gain and who would lose? The outcomes of the political battles over changes in the tax system often hinge on the answers to such questions. This paper will discuss the economic consequences of taxation and the factors that influence where the burden of various taxes really falls. It will review some of the discussions in the economic literature. Finally, it will suggest that a shift to a markedly different type of tax system would benefit all players in the economy.
