Your science teacher hands you a small container filled with an unknown liquid substance. he asks you to measure the mass of the liquid. what lab equipment will you use and how will you calculate the mass of just the liquid? be sure to describe the process you would follow step-by-step.

The laboratory equipment to be used are the balance and a beaker whose size depends on the volume of the unknown). First, the mass of the empty container then pour in all the liquid and read off the mass. Subtract the mass of the empty container from the total mass. 

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.
