If the temperature in the tank is decreased this would imply that the kinetic energy of molecule decreases because of the ideal gas law:
PV= nRT (Since Pressure is directly proportional to Temperature).
So the answer is B.The air pressure in the rigid tank decreases.
Hope this helps you.
Weight = (mass) x (gravity)
so
Mass = (weight) / (gravity)
Mass = (3000N) / (9.8 m/s^2)
Mass = 306.1 kg

Answer:
The ion is now -1
Explanation:
the number of electrons is greater than the number of protons, therefore it has a negative charge
Answer:
D) the bending of a wave as it moves around an obstacle or passes through a narrow opening
Explanation:
Even though light travels in straight line, it will bend around objects if their size is comparative to its wavelength. This phenomenon is called diffraction.
Light will also bend if the light travels from one medium to another medium at an angle, but that is called refraction.
Diffraction occurs in one medium. Refraction occurs when light travels from one medium to another.
A.Salinity
The deeper you make your way the hotter it gets because it is getting closer to the inner core which is 4000-4700 Degrees Celsius so that definitely would not be the answer. It also gets more and more dense and the pressure changes and you can see this by the fact that some mantles are liquid but because of the pressure it forces it into a solid. Sorry for the terrible explanation, I am bad at explaining things. Hope this helps!
