Work done = change in kinetic energy Final K.E -- Initial K.E = (½mv² - ½mu²) = ½m (v²-u²) =½ 1500 (100-400) =½ (1500×300) = 450,000÷2 = 225,000 🙂

[@Prashant_Sng7]

Potential energy 😂😂😂

[@x-sizzord4432]

Waah

[@vineetyadav4869]

Given : t=6 hrs P=0.06 kW Thus energy consumed per day is: E=Pt=0.06×6=0.36 kWh=0.36 units

[@ZxDON.]

Bhai seconds mai karna hoga 6hours ko

[@khushiverma7e547]

Nhi kyuki commercial unit of energy Kwh (Kilo watt Hour ) hoti h bro.... Since ( 1kwh=1unit ) 👀🤔

[@iqooneo6418]

Last question answer is... E=power × time E= 0.060×6 E= 0.0360kwh And then, Ikwh = 0.0360÷1000w 1kwh= 0.36 unit

[@user-kl7sx6ok5z]

Right bro 👊

[@07diptigupta61]

Right.. Tqq.

[@Priya-ss7lg]

Ok

[@P.R.A.S.H.A.N.T.]

Easy pesy

[@bhuneshwaripeter9669]

Is correct answer

[@Jahedkhan-p1d]

But sir that 2question you gave after the topic of work done the anwer will be 0 because that porter lift the lagguage on his head so force is perpendicular to displacement.

[@rohitchouhan4700]

Last question ka answer hai energy = power × time =0.6×6 = 0.36 KWh = 0.36 unit

[@prachianddherya7758]

U = 10m/s. V=20m/s mass =1500 Work done=change in kinetic energy = Final k.E- Initial K.E =½mv². -½mu² =½m(v²-u²) =½ 1500 (100-400) =½ (1500×300) =450,000÷2 =225,000 ans

Final K.E. - Initial K.E. =1/2 mv^2 - 1/2 mu^2 =1/2*1500*20^2 - 1/2*1500*10^2 =1/2*1500*400 - 1/2*1500*100 =300,000 - 75,000 =225,000 joule
