The body reacts by giving out fluids to cool the body that is known as sweat
Answer:
In the given diagram Arrow Y indicates the second law of thermodynamics.
Explanation:
Second law of thermodynamics:
Total entropy of the system remains constant for an isolated system. If the amount of heat is converted into work there is loss of energy to the surrounding.
Arrow W:
It represent the work done by the piston for its movement. From second law of thermodynamic amount of heat is converted into work there is loss of energy to the surrounding.
This part doesn't represent the loss of heat to the surrounding. Thus, it do not indicate second law of thermodynamic.
Arrow Y:
It represent the heat added when work is done by the piston for its movement. From second law of thermodynamic amount of heat is converted into work there is loss of energy to the surrounding.
This part represents the absorption of heat to the surrounding. Thus, it indicates second law of thermodynamic.
Arrow Z:
It represent the work done by the piston for its movement. From second law of thermodynamic amount of heat is converted into work there is loss of energy to the surrounding.
This part doesn't represent the loss of heat to the surrounding. Thus, it do not indicate second law of thermodynamic.
Thus, only arrow Y indicates the second law of thermodynamics.
Answer:
Explanation:
Let m be the mass of a little car and m' be the mass of another car.
We know that,
Force = mass × acceleration
ATQ,
m × a = 2m × a'
a = 2 × a'
So, the acceleration of another little car is equal to .
Answer:
When Copernicus first systematically created his Sun-centered model of the universe, it did not lead to substantially better predictions of planetary positions than the Ptolemaic model because the Catholic Church, which was the power at the time, stated it was false, and anybody who believed Copernicus and spread the "myth" were excommunicated or even executed. This was because a sun centered universe would mean that everything the Catholic Church had been teaching about how the Earth was the center of the universe would be false. If people believed it, the church would no longer be seen as the infallible authority, so they needed to stop it from spreading.
Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gases, liquids, and solids including vibration, sound, ultrasound, and infrasound. Cheers.
