The correct answer is entropy.
In fact, second law of thermodynamics states that the total entropy of an isolated system can never decrease. It can remain constant if the system is in equilibrium or in case of a reversible process: however, perfectly reversible process do not exist in the real world, so the entropy of a system always increases whenever there is a process that involves energy changes.
The total energy produced by the generator is 3.45 kJ. Of this energy, 2.23 kJ are lost because friction and electrical resistance, so this amount of energy is converted into thermal energy. This means that the rest of the energy is available as electric energy, and it is equal to:
Answer:
The correct answer to the following question will be "41.87 m".
Explanation:
The given values are:
The speed of trooper = ![30.1 \ m/s](https://tex.z-dn.net/?f=30.1%20%5C%20m%2Fs)
The velocity of red car = ![45.4 \ m/s](https://tex.z-dn.net/?f=45.4%20%5C%20m%2Fs)
Now,
A red car goes as far as possible until the speed or velocity of the troops is the same as that of of the red car at
(∵
)
![t=5.56 \ sec](https://tex.z-dn.net/?f=t%3D5.56%20%5C%20sec)
then,
The distance covered by trooper,
![t1=30\times 5.56+\frac{1}{2}\times 2.7\times (5.56)^2](https://tex.z-dn.net/?f=t1%3D30%5Ctimes%205.56%2B%5Cfrac%7B1%7D%7B2%7D%5Ctimes%202.7%5Ctimes%20%285.56%29%5E2)
![=208.33 \ m](https://tex.z-dn.net/?f=%3D208.33%20%5C%20m)
The distance covered by red car,
= ![45\times 5.56](https://tex.z-dn.net/?f=45%5Ctimes%205.56)
= ![250.2 \ m](https://tex.z-dn.net/?f=250.2%20%5C%20m)
Maximum distance = ![250.2-208.33](https://tex.z-dn.net/?f=250.2-208.33)
=
Answer:
he same direction the magnitude of the resultant is equal to the scalar sum of the magnitude of the forces, but if they are applied in different directions the magnitude must be found using the Pythagorean theorem
Explanation:
When there are several applied forces, if they are all in the same direction the magnitude of the resultant is equal to the scalar sum of the magnitude of the forces, but if they are applied in different directions the magnitude must be found using the Pythagorean theorem, so which the resulting dowry is less than the sum of the magnitudes.
Let's carry out an example with two forces, F1 and F2 of equal magnitudes
if they are in the same direction
F_total = F₁ + F₂ = 2 F
if they are at 90º
F_total =
if they are at 180º
F_total = F₁ -F₂ = 0

is that a question or a statement lol
