The cern particle accelerator is circular with a circumference of 7.0 km.
(a) what is the acceleration of the protons (m = 1.67 × 10−27 kg) that move around the accelerator at 5% of the speed of light? (the speed of light is v = 3.00 × 108 m/s. )
(b) what is the force on the protons?

Amanometer is used to measure the air pressure in a tank. the fluid used has a specific gravity of 1.25, and the differential height between the two arms of the manometer is 34 in. if the local atmospheric pressure is 12.7 psia, determine the absolute pressure in the tank for the cases of the
