Which device often is designed to have liquid enclosed in a glass tube?

Thermometers have liquids encased in a glass tube. In the past, liquid mercury was used. However, due to health concerns and environmental issues associated with mercury, many new thermometers use a red-dyed ethanol that will evaporate much more quickly and is much less toxic than mercury.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
