Answer» energy is equivalent to 6.25×10¹⁸ EV (electron-volt) [Option.2]Some EXTRA Information:-• Energy is defined as the capacity to do work. More the energy in a body, more is the work the body can do.• Energy is a scalar quanity.• The S.I. UNIT of energy is Joule [J] The C.G.S unit of energy is erg.• Other units of energy are electron volt [eV], calorie [cal] , kilowatt-hour [kWh].• → 1 ev = 1.6×10-19 J → 1 cal = 4.186 J → 1 kWh = 3.6×10⁶ J• Some FORMS of energy, AVAILABLE naturally or created artifically are as follows :-1. Chemical Energy2. Heat Energy3. Light Energy4. Electrical Energy5. Nuclear Energy6. Mechanical Energy |
