Answer 1

2. zamień na kilowatogodziny

1 J = 1Ws=0,001kWs * 1/3600h = 0,00000028kWh

1 kJ =0,00028kWh

1 MJ =0,28Kwh

12 700 J =  12700J:3600000J= 0,00352Kwh

20 kJ =3600*20= 180Kwh

1,7 MJ =0,217 kWh

3. zamień na dżule

1 kWh =1000Wh=1000*3600Ws=3600000J

2 kWh =2000w*3600s= 7200000J

15,2 kWh =15200w*3600s= 54720000J

0,08 kWh =80w*3600s=288000J

153 kWh =153000*3600=550800000J

12,07 kWh =12070*3600=43452000J
