Question

przelicz jednostki a) 1200ws na J' b) 10,8MJ na kWh c) 0,2kWh na J d) 32,4 *10^9J na kWh e) 25kWh na MJ

Answer 1

a) 1200Ws=1200J (W*s=J)

b) 10,8MJ=10,8*1000000J=10800000J

10800000J*1/3600000kWh=3kWh

c) 0,2kWh=0,2*3600000J=720000J

d) 32,4*10⁹J=32,4*1000000000J=324000000000J

32400000000J*1/3600000kWh=9000kWh

e) 25kWh=25*3600000J=90000000J=90MJ
