The sofa is softer than the stool, and sitting on the sofa, the force area of the body is relatively large, and the pressure is small, so it is more comfortable. >>>More
Answer: C
What is considered is the pressure, the pressure is constant, the force area is large, P=F s, s is large, and the pressure is small. >>>More
Sitting on the sofa and the wooden bench, the pressure on the two is equal, equal to the magnitude of the gravitational force experienced by the person But the sofa is soft, and the contact area between the person sitting on it is larger than the contact area on the wooden bench From the formula p=F S, it can be seen that the pressure generated by the person on the sofa is small Therefore, the upward force generated by the sofa on the person per unit area is also small Therefore, the person sitting on the sofa is more comfortable than sitting on the wooden bench
This should be due to the fact that the thermal conductivity of the two substances is not the same. >>>More
The sofa is soft, will fit the curve of the human body and concave it, increase the contact area of the person sitting on it, because the gravity of the person is certain, so the pressure of the person on the sofa or chair is inversely proportional to the contact area, and the pressure of the sofa or chair on the person is less equal to the pressure of the person on the sofa or chair, so the pressure of the sofa on the human body is smaller, and it feels more comfortable.
