Webb26 juli 2024 · Learn about and revise energy and how it’s related to work, power and efficiency with GCSE Bitesize Physics. WebbPower = 60 + 60 = 120 watts Energy = Power x Time = 120 x 12 = 1.44 kWh (kilowatt-hour) Now for the next 12 hours only bulb A would remain ON hence, Power = 60 watts Energy = 60 x 12 = 0.72 kW h In this scenario, the power consumed during the whole day varies as one bulb is turned ON for only 12 hours, so we have to calculate average power,

WebbThe work we do on the rock also equals the rock’s gain in gravitational potential energy, PEe. W = P E e = m g d. Kinetic energy depends on the mass of an object and its velocity, v. K E = 1 2 m v 2. When we drop the rock the force of gravity causes the rock to fall, giving the rock kinetic energy. WebbPhysics Numerical विज्ञान के आंकिक सवालों के Calculation ...
