Anato base in northern norway is warmed with a heat pump that uses 7.0 °c ocean water as the cold reservoir. heat extracted from the ocean water warms fluid to 80°c; this warmed fluid is used to heat the building. when the system is working at full capacity, 2,000 kw of heat is delivered to the building at the cost of 600 kw of electric energy. a. what is the actual coefficient of performance of the system? b. what is the theoretical maximum coefficient of performance of the system?

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.
