Salt water spray blowing on it each day. This can quickly lead to rust because of all the salt.
Potential energy (PEI due to gravity = mgh
Where, m= mass of the billboard, g=gravitational acceleration (9.81 m/s^2), h = height
Therefore,
m= PE/(gh) = 175000/(9.81*30) = 594.63 kg
Answer:
A. The temperature and pressure above which a supercritical fluid exist.
Explanation:
The physical states of a substance under different temperature and pressure conditions is represented by a phase diagram. In this diagram, normally the pressure is represented on the y-axis while the temperature is present on the x-axis. There is a point on this diagram called the critical point, beyond this point the liquid and the gaseous phase become indistinguishable. When the substance surpasses the critical point, it is referred as a supercritical fluid.
From the above description, all the options other than A is false.
