The maximum amount of work that can be extracted is equal to the changein Gibbs free energy___________.
steposvetlana [31]

Answer:

The statement is true

Explanation:

The Gibbs free energy is defined as:

ΔG = ΔH - TΔS

     Where  ΔH : Change in the  enthalpy

                   T : The temperature

                  ΔS : Change in the entropy

And the Gibbs free energy is a thermodynamic potential that can be used to calculate the maximum of reversible work that may be performed by a thermodynamic system at a constant temperature and pressure.

If the thermodynamic process is isothermal and isobaric, then the statement is true.

Daniel [21]

Answer:

v_2=-133.17m/s, the minus meaning west.

Explanation:

We know that linear momentum must be conserved, so it will be the same before (p_i) and after (p_f) the explosion. We will take the east direction as positive.

Before the explosion we have p_i=m_iv_i=Mv_i.

After the explosion we have pieces 1 and 2, so p_f=m_1v_1+m_2v_2.

These equations must be vectorial but since we look at the instants before and after the explosions and the bomb fragments in only 2 pieces the problem can be simplified in one dimension with direction east-west.

Since we know momentum must be conserved we have:

Mv_i=m_1v_1+m_2v_2

Which means (since we want v_2 and M=m_1+m_2):

v_2=\frac{Mv_i-m_1v_1}{m_2}=\frac{Mv_i-m_1v_1}{M-m_1}

So for our values we have:

v_2=\frac{(145kg)(24m/s)-(115kg)(65m/s)}{(145kg-115kg)}=-133.17m/s

Kevin jumps straight up in the air to a height of 1 meter.At the top of his jump, he has potential energy of 1,000 joules.Answer
Llana [10]
Gravitational potential energy can be given by the equation
PE = mgh
where m is the mass,
g is the gravitational constant 9.81 or 10 depending on rounding
and h is the height

well weight is a force equiavlent to
W= m*g

so comparing that to the potential energy equation, divide the potential energy by the height and you will get weight in Newtons

yanalaym [24]

The spin quantum number is represented by the symbol m s a nd has the possible values  +1/2.-1/  corresponding to the two directions of the electron's magnetic field.

The magnetic quantum quantity tells us what number of orbitals there are in a subshell and the feasible orientations of those orbitals. Its value is dependent on the angular momentum quantum range.

The  magnetic discipline is an area in area close to a magnet or an electric contemporary wherein a physical area is produced from a shifting electric rate that creates force on some other shifting electric rate. An instance of a magnetic field is the Earth's magnetic

All magnets have north and south poles. contrary poles are drawn to every other, whilst the identical poles repel each different. when you rub a chunk of iron alongside a magnet, the north-in search of poles of the atoms in the iron line up inside the identical route. The force generated by using the aligned atoms creates a magnetic subject.
