A hydraulic system for a dentist's chair is designed to be able to lift 3,112 newtons. The surface area over which this force is applied is 707 cm2. What force must be applied to the activator end of the system if the button has a surface area of 3.14 cm2? 700,700 N 1.41 N 0.0724 N 13.8 N
Weegy: 3112 : 0.707 dm^2 = x : 0.00314 dm^2 x = 13.8 N area=58.8cm^2=.0058 m^2 pressure=20275 Pascals or 2 N/cm^2 So the units on your choices are incorrect. (More)

This statement is False.

At the freezing point of water, the temperature of the Kelvin scale reads 273 K.
0º is the freezing point of water in Celsius.

0 °C = 273.15 K.

This definition fixes the magnitude of both the degree Celsius and the kelvin as precisely 1 part in 273.16 (approximately 0.00366) of the difference between absolute zero and the triple point of water. Thus, it sets the magnitude of one degree Celsius and that of one kelvin as exactly the same. Additionally, it establishes the difference between the two scales' null points as being precisely 273.15 degrees Celsius (-273.15 °C = 0 K and 0 °C = 273.15 K).[3]

@kidcarbon- yes the equal each other but the question asks if they both read zero. They do not both read zero.
