Answer:
Because with Gibbs free energy we can determine the spuriousity of reaction occurrence
Explanation:
Gibbs energy: is a thermodynamic potential that has units of energy that gives the condition of equilibrium and spontaneity for a chemical reaction (at constant pressure and temperature).
In the chemical thermodynamics of reactions and in non-cyclic processes, there are four useful quantities called "thermodynamic potentials". These are internal energy, enthalpy, Helmholtz free energy and Gibbs free energy.
While Entropy is a thermodynamic function that is a measure of the unusable part of the energy contained in a system or matter. It serves to measure the degree of disorder within a process and allows us to distinguish useful energy, which is what becomes entirely work, of useless, which is lost in the environment.
The density is 81.4 g/m3. Before you start plugging numbers into the density formula (D=M/V), you should convert 104 kg to grams, which ends up being 104,000 grams. Then you can plug in the 104,000 grams and 1,278 m3 into the formula. When you divide the mass by the volume, you get a really long decimal, which you can round to 81.4 g/m3, or whatever place your teacher wants you to round to.
To develop this problem it is necessary to use the equations of description of the simple harmonic movement in which the acceleration and angular velocity are expressed as a function of the Amplitude.
Our values are given as
The angular velocity of a body can be described as a function of frequency as
PART A) The expression for the maximum angular velocity is given by the amplitude so that
PART B) The maximum acceleration on your part would be given by the expression
Refer to the diagram shown below.
The force, F, is applied at 5 cm from the elbow.
For dynamic equilibrium, the sum of moments about the elbow is zero.
Take moments about the elbow.
(5 cm)*(F N) - (30 cm)*(250 N) = 0
F = (30*250)/5 = 1500 N
Answer: 1500 N
