State the relation between the bigger unit of energy and the SI unit of energy |
|
Answer» Explanation:mark my answer as branliest[please]The SI unit of energy is the joule (J). The joule has BASE UNITS of kg·m²/s² = N·m. A joule is defined as the work done or energy required to EXERT a force of one newton for a distance of one metre.Since, we know that SI unit of energy is represented by Joule. We CONVERT all the different units in the form of Joules. HENCE, Option B is the largest unit of energy and hence it is practically used in everyday life of electric consumption |

If a man pushes a heavy box and the boxdoes not move, he does no work. Explain briefly. |
|
Answer» Work power and energyExplanation:Work = Force • Displacement Force and displacement both are VECTOR quantity.Work done is dot PRODUCT of Force and displacement So ; If a man applies force on BOX ,Box does not move then displacement is ZERO but force is not zero . So ; Force multiply by zero displacement the result would be zero . ANSWER :- Hence ; Work done by man on box would be zero. |
