Answer:
Explanation:
a = (vf - vi) / t
a = (50 - 90) / 10.0
a = -4 km/h/s(1000 m/km / 3600 s/h)
a = - 1.11 m/s²
Answer:
Liquid
Explanation:
Before anything evaporates, it is in a liquid state.
Answer:
Explanation:
Let establish a control volume in the industrial pressure cooker, which is a transient state system. From the First Law of Thermodynamics, the heating process is modelled:
The heat transfered to the cooker is:
Properties at each state are described below:
State 1
State 2
The heat transfered to the cooker is:
I don't get what you are trying to ask or what's the question?
Answer:
Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.
