To save on heating costs, the owner of a greenhouse keeps 380 kg of water around in barrels. During a winter day, the water is heated by the sun to 19.5° C. During the night the water freezes into ice at 0.0° C in 6 hours. What is the minimum ampere rating of an electric heating system (120 V) that would provide the same heating effect as the water does?

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

its a 5.5 n

glad that
