A helium atom would never explode and is non-reactive, whereas a hydrogen atom is.

A helium atom is not flammable because it is one of the Inert Gasses; In contrast, Hydrogen is flammable. It reacts explosively with Oxygen


I think I am correct, but comment if I'm wrong :-)

The other answer here says nothing about the structures
of a Hydrogen atom or a Helium atom.


In "classical terms" ... where we picture an atom something
like a tiny tiny solar system ...

-- The nucleus of a Hydrogen atom is a single proton,
whereas the nucleus of a Helium atom is a tightly bound
bundle of four particles ... 2 protons and 2 neutrons. 
This also means that every atom of Helium has 4 times
the mass of a Hydrogen atom.

-- In addition to the atomic nucleus, one electrically-neutral
atom of Hydrogen has an electron associated with the nucleus
and at some distance from it, whereas an electrically-neutral atom
of Helium has two electrons.

The sun

Explanation:

In this system the energy of the sun heats the water in the pipe, producing a high pressured steam, which is used for moving a turbine and producing electricity, is a transformation of energy from solar to thermal, then to mechanical to electrical.

Find the sum of the vectors: 40m/s2 Northeast, 10 m/s2 Northeast
podryga [215]

Answer:

Explanation:

Since both vectors are pointing on the same direction (Northeast), the sum of them will point in that same direction, and its magnitud will be the sum of the magnitudes of each vector (40m/s2+10m/s2). This problem is just a problem in one dimension. The sum of the vectors is then 50m/s2 Northeast.

A pitot tube indicates a pressure of 155 kPa when placed in an air stream in which the temperature is 15°C and the Mach number i
mel-nik [20]

To solve this problem we will start by defining the relationship of the pitot tube and the value indicated in the pressure. We will take advantage of this relationship to obtain a ratio between the defined pressures and proceed to calculate the total and static pressure of the system through the correlation of pressure in isotropic systems. Finally we will perform this same procedure for pressure. Pitot tube measure the total pressure minus static pressure, then

p_0 - p = 155kPa

\frac{p_0}{p} -1 = \frac{155}{p}

\frac{p_0}{p} = \frac{155}{p} +1

Express the total pressure and static pressure ratio

\frac{p_0}{p} = [1+\frac{\gamma-1}{2}M^2]^{\frac{\gamma}{\gamma-1}}

\frac{155}{p} +1 = [1+\frac{1.4-1}{2}(0.7)^2]^{\frac{1.4}{1.4-1}}

\frac{155}{p} +1=1.3871

p = 400.4kPa

Hence the static pressure is 400.4kPa

Express stagnation to static temperature ratio,

\frac{T_0}{T} = 1+\frac{\gamma-1}{2}M^2

\frac{T_0}{(15+273)K} = 1+\frac{1.4-1}{2}(0.7)^2

T_0 = 316.224K

Therefore the stagnation temperature is 316.224K
