# What's the acceleration?

An accelerometer is made using tubular sections, as shown below. The accelerometer is placed in a rocket that travels in the $$\vec{x}$$ direction, and the liquid levels are steady at $$\SI{20}{\centi\meter}$$ and $$\SI{10}{\centi\meter}.$$

Find the magnitude of the rocket’s acceleration (in $$\text{m/s}^2$$). Submit your answer to 3 decimal places.


Details and Assumptions:

• The diameter of the tube is much smaller than the heights of the liquid in the two arms.
• $$g = 10 \text{ m/s}^{2}.$$
