(a) calculate the absolute pressure at the bottom of a fresh-water lake at a depth of 28.6 m. assume the density of the water is 1.00 ✕ 103 kg/m3 and the air above is at a pressure of 101.3 kpa. (b) what force is exerted by the water on the window of an underwater vehicle at this depth if the window is circular and has a diameter of 30.0 cm?

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
