The volume of the shell that you described would be:
Now we can rewrite the given integral:
I have attached the picture explaining how we got the formula for the volume.
On the picture, I marked the rectangle. You can of this rectangle as the base, and the height would be the circumference of the cylinder.

Complete Question:
A.Compute no of electrons you expect to count if silicon detector is struck with a 1.04 Mev gamma ray produced in a decay of 136 Cs nucleus.
b.Explain counting of electrons is more precise as the detector is cooled well below room temperature
Answer:
a.
Gamma ray energy =
photon strikes the surface excite the electrons to move from valence band to conduction band where then counted by detector.
energy gap between valence band and conduction band in case of silicon = 1.1 eV
The minimum amount of energy required is 1.1 ev
minimum number of electron counted is = 
=
b.
In the case of semi conductors
forbidden energy gap in inversely proportional to temperature
with decrease in temperature forbidden energy gap increases,hence electrons jumping from valence band to conduction band decreases and hence counting by detector decreases
Answer:
Convective zone, chromosphere, corona
Explanation:
A star like the Sun is divided into different layers according to pressure, density, temperature, and the mechanics of energy transport (in the case of the convective zone and radiative zone) for each of those layers.
In stars, there is an equilibrium between two forces, the force of gravity in the inward direction due to their own mass and the radiation pressure in the upward direction as a consequence of the nuclear reaction in their core, that is known as hydrostatic equilibrium.
That leads to different layers according with the properties described above.
Near the core, in the Sun, there is a radiative zone since radiation is the best mechanism of energy transport in this area. Then, in the next layer, it can be found that convection becomes a more efficient way of energy transport that radiation due to the fact that the inner part of the convection zone is at a greater temperature than the outer one.
Finally, there is the atmosphere of the Sun (chromosphere, photosphere, and corona).
Key terms:
Convection: Transport of energy due to different in density and temperature of a material (liquid, gas).

Answer:
363000 J or 363 kJ
Explanation:
Because the car is not rotating, it has no rotational kinetic energy. Its kinetic energy is then simply
