Answer:
The capillary rise of the glycerin is most nearly 
Explanation:
From the question we are told that
The diameter of the glass tube is 
The density of glycerin is 
The surface tension of the glycerin is 
The capillary rise of the glycerin is mathematically represented as
substituting value
Therefore the height of the glass tube the glycerin was able to cover is
Answer:
The correct answer is - oxygen.
Explanation:
Cardiovascular endurance is the ability to do physical activity or exercise without affecting or being tired for a longer time period. Aerobic exercise or activity can help to increase cardiovascular endurance.

Remote sensing is used in numerous fields, including geography<span> and most Earth Science disciplines.</span><span> It also has military, intelligence, commercial, economic, planning, and humanitarian applications.</span>
Answer:
The time it takes light to cover 1.5 km was too short to be measured by Galileo's instruments.
Explanation:
The speed of light is 
, which means the time it takes to cover a distance of 1.5 km (or 1,500m) will be
which is 
of a second! This time delay could in no way be measured by Galileo considering the fact that he was using his heartbeat to measure time!
