If electrical energy costs 12 cents, or $0.12, per kilowatt-hour, how much does it cost to operate an electric over for 5.0 h if it carries a current of 20.0 A at 220 V?

A particle moves through angular displacement ø on a circular path of radius r. The linear displacement will be

The avg moler heat capacities of ice and water are 37.8 and 75.6jmol-1 respectively and the enthalpy of fusion of ice is 6.012kjmol-1 the amount of heat required to change 10 gm of ice at -10°c to water at10°c would be

120 degrees

Why we multiply w.d with length of the incline
