Atank container has the dimensions listed below. the air pressure inside the top of the tank is 52kpa (gage). calculate the force (differential force) on the bottom of the container (answer in kn). note the tank top is sealed, not open to atmosphere, it is pressurized to 52kpa. the specific weight of water on earth at 5°c is 62.43 lbf/ft3 or 9.807 kn/m3

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?
