The tank at right is moving uphill. We don't know if it's accelerating or decelerating but we do know the angle of the fluid inside the tank.

Find a$)$ the value of the acceleration $\text{'}$a$\text{'}$ and b$)$ whether this is accelerating uphill or decelerating and c$)$ the gage pressure at Pt A $($in Pascal$)$ if the fluid is Glycerin at $20$ deg C$.$
