Answer:All of the above
Explanation:
9.62 psi means 497.49 mm of Hg pressure
for (a)19.58 inches is equals to 497.49 mm of Hg 
(b)atmospheric pressure is 14.69 psi
vaccum gauge is 9.62psi
absolute pressure is=14.69-9.62=5.07
(c)vaccum means air is sucked and there is negative pressure so it tells about below atmospheric pressure.
thus all are correct

Answer:
   Engineers can design a train with a regenerative braking system
Explanation:
Assuming the point of the question is that the engineers want to focus on using energy efficiently when starting and stopping, they would likely want to consider a regenerative braking system. Such a system can store energy during braking so that it can be used during starting, reducing the amount of energy that must be supplied by an outside power source.
